Vapor condensation system WSO3 The WSO3 vapor condensation system was commissioned in September 2018. Technologically, the design sets new standards. The picture shows a part of the 3D planning.
Main wastewater treatment plant Stuttgart Mühlhausen The main wastewater treatment plant in Mühlhausen processes the wastewater of more than 1,300,000 population equivalents. This makes the plant one of the largest in Germany. EfU is working on more than 8 projects simultaneously at this site. The operator of this plant, SES, is a technological leader in many areas. EfU provides support in many areas and contributes to maintaining the leading position long-term.
Wood combustion heat center We as a planning office prefer CO2-neutral technologies. The shown wood combustor of the company Burkhardt is one of them. Here, a synthesis gas is produced from wood in a fully automatic operation 7000 h/a, which is then converted into electricity in an engine. The electricity generated is fed into the grid and the heat produced is used to 100%. The customer is a local heating network. To enable the high running times of the combustor, EfU designed and commissioned a heat storage tank with 3,000,000 liters of water. The predicted operating times were already achieved in the second year of operation.
Sewage sludge incineration plant Munich Munich has been operating a modern and efficient sewage sludge incineration plant for about 25 years. Munich's municipal drainage system commissioned the planning consortium Wandschneider und Gutjahr, PFI and EfU to design a completely new incineration plant including dewatering and drying. With a throughput performance of approx. 35,000 to 40,000 t TS/a, the plant is one of the larger ones in Germany.
RDF Mannheim (municipal drainage system) The wastewater treatment plant in Mannheim treats the wastewater of 600,000 population equivalents. The resulting sludge is currently dried in a high-temperature drum dryer. A low-temperature belt dryer is now being installed. It is capable of drying the entire sludge with an inlet temperature of 80 °C. Hydraulically, this requirement is demanding with a capacity of 3 x 2.7 MW. EfU is developing process engineering solutions so that drying can be carried out purely with the waste heat from various units.
Heat transfer station Stuttgart EfU planned and implemented a redundant heat transfer station for the main wastewater treatment plant in Stuttgart Mühlhausen. Despite the transfer capacity of 7000 kW, the local conditions required a very compact design. The customer's requirement of good accessibility for maintenance and inspection work was also met by EfU's planning.
Emter sewage sludge incineration in Schongau Modernization and extension as well as operational optimization of a sewage sludge mono-incineration plant with 12 MW firing power incl. sewage sludge drying and flue gas cleaning according to the 17th Ordinance on the Implementation of the Federal Emission Control Act.
Heating center Waldmohr Heating center with heat connection and coupling to the existing system. Wood chips, shredded wood pallets, miscanthus and cherry stones are used as fuel. Power 100 kW.
Wood combustion Horb a.N. Integration of two wood combustors with a firing power of 950 kW into the heating network. This involves generating a synthesis gas from wood pellets and utilizing this in a gas engine. Each of the two gas engines generates 200 kW of electricity and 280 kW of heat.
Large-capacity heat storage tank In order to be able to operate the entire local heating network in Horb without fossil fuels, a large heat buffer is required. For this purpose, a heat storage tank with 3,000,000 liters is being built. This is capable of balancing out the disparities between energy generation and energy consumption. It can absorb or release power of up to 3,500 kW.
