Essential site components disappear into the ground when fire departments build. It is easier for all parties involved in the construction when the equipment installed underground comes completely from a single source. This was the case in Dornstadt.

There had never been such a deployment order before: Relocation. From the old station to the new one. The new station is located in St. Florian Weg, but above all it is conveniently situated. With quick access to those sections of the A8 and B10 that belong to the operational area of the Dornstadt volunteer fire department.

Together with four other districts, Dornstadt forms a community association just a few kilometers north of Ulm. Each sub-community has its own fire department. The fire department in the core village of Dornstadt had moved into a temporary domicile in 1977, and the provisional arrangement lasted for more than 40 years. But now there is the new building. “On July 03, 2021, the time had finally come and we could move into our newly built fire station,” the 41 firefighters rejoice on their website.

In the new building, there are boxes for the five emergency vehicles and the rescue boat, as well as a wash hall and a workshop area. The members of the fire department have access to a recreation, fitness and training room, separate changing areas, offices and a control center for coordinating operations.

Heat in the new fire station comes from an environmentally friendly pellet heating system. It points to the site’s underground infrastructure, which deserves special attention. This is because all sorts of things lie beneath the pavement of the open spaces: the pellet bunker, of course, a firefighting water tank, and finally a light liquid separator with downstream sampling shaft. In addition, there is an infiltration trench for the rainwater that accumulates on the driving surfaces.

Getting all this from a single source – in addition to the individual components, also planning services, installation, leak testing, commissioning and instruction – was definitely a relief for the developer, planner and construction company. As a result, speedy processes around the relevant trades in all phases of the construction project can be booked as a profit, as can later the synergies in the maintenance of the installed systems by their manufacturer Mall (Donaueschingen).

For the environmentally safe pretreatment of the wash water from the vehicle cleaning, an ABKW separator of the NeutraCom type – System A with general approval and integrated warning device – as well as a NeutraCheck sampling shaft were installed. Especially for this project, Mall had taken over all services from dimensioning and planning to design drawings and execution. The task of the separator is to retain the light liquid components in the wastewater before the treated wastewater flow enters the sewer system.

The volume of 9.25 cubic meters of extinguishing water for operations and drills is stored in a reinforced concrete tank, which is cast in the same jointless manner as the tank structures of the separator and sampling shaft. The Mall ThermoPel pellet storage tank, which is accompanied by the CaviPro seepage shaft, is no different. The latter infiltrates the condensation water that accumulates in the neck of the shaft above the pellet store, which has a capacity of 15 cubic meters.

Not only the equipment, but also the properties of fire departments, rescue services and THW should correspond to the current state of the art. This necessarily includes standard-compliant drainage solutions for new buildings and conversions. For wastewater generated during vehicle maintenance, EN 858 in combination with DIN 1999-100 requires the mandatory installation of a light liquid separator. Extinguishing foam produced during exercises must not be allowed to enter the sewage system or waterways. This necessitates liquid-tight sealed surfaces and collection containers with sufficient retention volume. It’s convenient when all this and much more can come as a compact package from a competent partner with many years of experience.

Presentation of pioneering solutions for autonomous driving

Published

on

At this year’s IAA MOBILITY in Munich, Continental is presenting solutions for the future of global mobility that are as innovative as they are sustainable. Under the motto “Safe. Connected. Convenient. Driving the future of mobility for 150 years”, the technology company is focusing on the safe, sustainable and connected mobility of people and their goods, both in Hall B1 (Stand C20) and virtually. To this end, Continental will be showcasing its latest solutions from the innovation fields of assisted and automated driving, high-performance computing and software for server-based architectures, safety technologies, user experience and sustainability.

“The results of our mobility study prove how great the need for individual mobility continues to be worldwide – especially in times of pandemic. People enjoy the freedoms of individual mobility while at the same time focusing on sustainability and emission-free driving. We offer pioneering solutions for this.”

– Nikolai Setzer, Chairman of the Board of Management

Consistently on the road to sustainability

At the IAA MOBILITY, the company is presenting a study of a particularly sustainable tire as a world first: the Conti GreenConcept. Its integrated sustainability concept sets new standards. Continental’s development engineers and materials experts have worked on three levels of impact to achieve this: At more than 50 percent, the tire contains a particularly high proportion of traceable, renewable and recycled materials. The tire concept is based on innovative, resource-saving lightweight construction technology and provides for an extended service life thanks to a renewable tread.

The proportion of renewable raw materials used in the Conti GreenConcept is 35 percent. The biomaterials used include natural rubber from dandelions, silicate from the ash of rice husks, and various vegetable oils and resins, which significantly reduces the proportion of crude oil-based materials. In addition, 17 percent recycled materials are used in the Conti GreenConcept. In addition to recycled steel and carbon black, Continental is using polyester from recycled PET bottles in the carcass of a tire for the first time.

Through a consistent lightweight design, the developers have significantly reduced the weight and rolling resistance of the concept tire. All the individual improvements together result in significantly lower rolling resistance for the Conti GreenConcept. According to internal measurements, it is around 25 percent below that of a tire with rolling resistance class A in the EU tire label, the best value in this area. This means that the Conti GreenConcept has a measurably positive effect on the environment. Lower rolling resistance means lower energy consumption by the vehicle. In electric vehicles, the range is extended accordingly by up to 6 percent.

Another plus point of the tire is its renewable tread. The concept means that it can be replaced several times at little cost in terms of time and material. This makes a significant contribution to conserving resources, because renewing the tread three times would ensure that the amount of material used for the carcass is halved in relation to its total mileage. Further information on the Conti GreenConcept concept tire is available in a separate press release.

Rolling into the green future on green tires

“The cars of the future will continue to need tires. We are making them more sustainable step by step, as our concept study proves. The Conti GreenConcept shows how Continental will completely switch its global tire production to the use of sustainable materials by 2050 at the latest. This underscores our goal of being the most progressive tire company along the entire value chain in terms of social need as well as eco and economic balance by 2030,” said Setzer, adding, “Step by step, we are putting sustainability on the road and climate protection on the road by the millions with our solutions and technologies.”

Sustainable and responsible business practices have been an integral part of Continental’s corporate strategy for many years. It is producing tangible results, as evidenced by a number of other innovations for sustainable and smart electric vehicles. Therefore, Setzer confirmed, “As early as 2022, we will make business with zero-emission vehicles completely CO2-neutral – worldwide. For 2040, we are aiming for zero CO2 emissions at all our plants worldwide. And we have set ourselves the major goal’ of operating in a completely climate-neutral manner along the entire value chain’ by 2050 at the latest.”

Ahead of the autonomous driving megatrend

Another focus of Continental’s presence at the trade show is dedicated to the megatrend of autonomous driving. Continental has already been driving developments for automated and autonomous mobility for many years and offers solutions. These include radar sensors and camera technologies, LiDAR sensors, automated driving high-performance computers and the complete software stack for assisted and automated driving as well as in-cabin monitoring. Increasingly, Continental is augmenting the functions of these technologies with artificial intelligence, such as deep learning methods, as well as know-how gained from handling large amounts of data.

“Global technology leadership in assisted and automated driving is and remains our goal. That is why we are not only presenting groundbreaking products and solutions for the mobility of tomorrow here at the IAA MOBILITY, but are also setting targeted industry standards with them at the same time,” said Setzer.

At the show, the company will demonstrate to visitors how the innovations help them in their everyday driving. They will experience greater safety and comfort when parking independently and how the system performs automated service functions such as washing the vehicles or even charging the vehicle batteries in the parking garage.

High-performance computers and software are at the heart of modern vehicles

The hearts of Continental’s developers are beating particularly fast as they drive the quiet revolution in electronic vehicle architecture. This is because modern vehicles are increasingly becoming part of the Internet of Everything. To this end, they will always be networked, rolling computers, defined by software and wireless data exchange. Instead of a complex network of numerous microcontrollers, a handful of high-performance computers and zone controllers will take over central control of all vehicle functions in such vehicles: in the cockpit, for chassis systems and automated driving.

“The software is what counts here. It is among the top expertise of our approximately 20,000 software and IT specialists with their many years of experience in the application of information technology in all areas of the vehicle,” explained Setzer, referring to the successful production launches in this area. “In 2020, we became the first automotive supplier in the world to put a high-performance computer for the car into series production. One such centerpiece has grown into many more to date, which we are showing here at the trade fair,” he added.

AMBIENC3 effortlessly combines driving, working and relaxing in one interior space

Seamless, barrier-free and intuitive: what applies to modern communication via the Internet also applies to the coming mobility experience. “The vehicle interior of the future will be trendier and multifunctional. It will merge cockpit, living and working space. It will become a third living space that can be used in a variety of ways. For this, users want the use of sustainable materials, bright designs and, of course, convenient, digital solutions,” said Setzer, summarizing the key mobility trends for the company, adding, “With our AMBIENC3 concept vehicle based on a T2 Bulli, we are demonstrating the strengths of our technologies and innovations, our sustainability and our design in an emotional way here at the trade show. True to the motto: retro meets future.”

With the AMBIENC3 – the name is a combination of the two English words “Ambience” and “3rd Space” – visitors to the trade fair will experience the future of the interior designed by Continental. The concept of the so-called third space refers to a shared space that differs from the home (first space) and the workplace (second space) or combines both. In this way, the AMBIENC3 combines worlds and conveys the trend themes of design, functionality, sustainability and individualization. Everything in and on the concept vehicle is new and innovative: the design language, the appearance, the handling, the lighting concept.

Smart surface solutions play a central role here, for example when they are enhanced by functional printing or combine greater comfort with passive climate control through breathability. Added to this are Ac2ated Sound, a complete sound experience without loudspeakers, and the ProViu360 driver assistance system, which gives the driver significantly better situational awareness through a camera surround system. Another element is the intelligent glazing with controllable blackout and heat functions. It saves energy and ensures a unique feeling of well-being.

The built-in solar archer uses photovoltaics for environmentally friendly energy generation. And the “eTravel.Companion” is a software-programmed travel companion that provides interactive and personalized support to the driver during the journey with tips and recommendations on the route, refueling or the condition of the vehicle.

The special feature of the innovative technology: The eTravel.Companion is linked to the smartphone and thus to the user, not to a single automobile. This means that all service benefits can also be used in different vehicles – a major advantage when car sharing or booking a rental car, for example. Thanks to artificially intelligent algorithms, the system is constantly learning and can offer individually tailored support for many facets of travel, including networked and smart solutions for greater climate and accident protection.

More and more innovations relating to mobility are helping to promote climate protection. Networking and the Internet are essential. In the future, almost everything that turns and moves will be networked and controlled via computer programs. This is the only way to fulfill the EU’s Green Deal, achieve the necessary efficiency gains and sustainably reduce greenhouse gases. Smart solutions are therefore an integral part of the mobile future.

They protect against accidents, avoid traffic congestion and reduce fuel consumption and pollutant emissions. The seamless smart mobility solutions show what is already possible today: from smart tires to vehicle sensors and actuators to networking and cloud services. The systems developed by Continental cover the entire effective chain, including the next generation of driver assistance, braking and restraint systems. In addition to climate protection, such technologies contribute to “Vision Zero”: a traffic world without accidents and victims that is no longer a utopia.

Construction of the first offshore wind farm on the high seas

Published

on

The first ship with foundations for the new Hollandse Kust Zuid offshore wind farm set off yesterday. Over the next two years, the world’s largest and the first offshore wind farm to be built without subsidies will be built off the Dutch coast. The fossil-free electricity generated at the wind farm will benefit households, businesses and industrial partners alike.

“With the construction of the world’s first offshore wind farm built without subsidies, we are opening a new chapter and showing that this market is increasingly developing. I am very proud and pleased that together with our industry partners we are taking a big step towards our goal – life without fossil fuels.”

– Martijn Hagens, CEO Vattenfall Netherlands

The company wants to enable a fossil-free life within a generation. Wind power plays an important role in this. It currently operates more than 1,200 wind turbines, and eight wind farms are under construction, both onshore and offshore.

Construction work for Hollandse Kust Zuid will begin with the installation of the monopile foundations. Each of these foundations is specially designed for the particular site. The heaviest and largest monopile weighs 955 tons and is 75 meters high, while the lightest and shortest still weighs 735 tons and is 62 meters high. The monopiles are installed in water depths ranging from 17 to 28 meters.

The installation vessel transports the foundations to their offshore location and positions itself at the exact spot. The ship’s crane then lifts the monopile into the water and lowers it until it reaches the seabed at a depth of 17 to 28 meters. It is then driven to the desired depth with a hydraulic hammer.

“Over the next few months, we will install dozens of foundations,” says project manager Ian Bremner. “There will be a break in the winter, as the weather is too bad and the sea too rough to work safely. In spring 2022, construction will resume and we will install the remaining foundations, followed by interconnecting cables and the wind turbines. According to current plans, the first turbines will be commissioned in spring 2022, and all turbines should be connected to the grid by summer 2023.”

Vattenfall is building Hollandse Kust Zuid together with its partner BASF. The wind farm will be located about 18 kilometers off the coasts of The Hague and Zandvoort, with the furthest wind turbines located 36 kilometers offshore. The 140 wind turbines will have a combined installed capacity of 1.5 gigawatts, making Hollandse Kust Zuid the largest offshore wind farm in the world.

The company will provide a significant portion of the fossil-free electricity generated by the wind farm to Dutch households and small businesses. BASF will use its share of the production to introduce innovative, low-emission technologies at several of its production sites in Europe.

New diode laser spectrometer with optimum combustion control

Published

on

Yokogawa Electric Corporation plans to launch its newly developed TDLS8200 tunable diode laser spectrometer as part of its OpreX™ Analyzers product family on May 6, 2021. The new product features the same low installation cost, high measurement stability and high reliability as its predecessor, the TDLS8100, and can simultaneously measure oxygen, carbon monoxide and methane gas concentrations directly and at high speed.

Development background

Excess air supplied during combustion control in heating furnaces absorbs heat in the furnace before exiting through the exhaust stack. This not only leads to heat loss, but can also generate large amounts of nitrogen oxides and sulfur oxides, which are a major cause of air pollution. On the other hand, if there is insufficient air supply, complete combustion does not occur, resulting in energy losses, emission of carbon monoxide and black smoke, and residual methane. Carbon monoxide and methane are flammable gases that can easily form an explosive mixture with air if they accumulate in a furnace. Therefore, in oil and gas, electric power, iron and steel, petrochemical, and ceramic plants, the concentrations of oxygen, carbon monoxide, and methane in furnaces must be monitored to ensure an efficient, environmentally friendly, and safe combustion process.

Features

1. Efficient combustion and high safety through stable, simultaneous measurement of oxygen, carbon monoxide and methane.

The main feature is the dual laser light source and optics, which enables simultaneous measurement of oxygen, carbon monoxide and methane concentrations for efficient combustion control. The direct measurement system is based on the use of lasers, which are easier to maintain than conventional sampling systems and more robust than catalyst-based sensors. This provides stable, simultaneous and lossless measurement of oxygen and carbon monoxide concentrations.

 

2. Easy replacement of sampling systems

The new product is an easy-to-install diode laser spectrometer with in-situ probe. Existing sampling systems can be quickly and easily replaced, which can be installed at the same port as the previous instrument. Since sample collection or preparation systems are unnecessary, little floor space is required.

 

3. Planned second version for measurements in environments with temperatures up to 850°C.

Available May 6, 2021, the spectrometer is designed for high temperatures of 600°C, making it ideal for use in boilers and exhaust ducts. A second version of the TDLS8200 for measurements at temperatures up to 850℃, such as when used in heating furnaces, is scheduled for release later this year.

Laser-based gas analyzers from Yokogawa

Yokogawa’s laser-based gas analyzers operate on the principle of tunable diode laser spectroscopy (TDLS) for concentration determination in gases. They offer best-in-class real-time performance because they are installed on channels and do not require a sampling system, so they can measure concentrations directly and at high speed. They use a spectral domain method that calculates gas concentration from the area in a light absorption distribution pattern – enabling accurate and stable concentration measurement even in an environment with temperature and/or pressure variations or in the presence of other types of gases or large amounts of dust.

Since their launch in 2008, Yokogawa’s laser gas analyzers have gained worldwide acceptance for their high reliability and performance in even the most challenging environments. Previously, Yokogawa had two models in its lineup: the TDLS8000 and the TDLS8100. The former is equipped with a separate laser light source and detector and is suitable for concentration measurement in high-temperature and high-pressure gases, even with high dust levels. The TDLS8100 is capable of measuring the concentration of gases whose flow rate ranges from 1 to 30 meters per second. With the addition of a third model to this series, simultaneous measurement of multiple gas types is now possible.
