The Kempten waste-to-energy plant consists of two incineration plants with combined heat and power in the Ursulasried industrial park in the city of Kempten . The complete waste processing plant consists of two plants, a wood and a waste incineration plant. The association for waste management (ZAK) is the owner and operator. The combined heat and power plant with district heating network supplies the city center with heat. According to its own information, the energy network supplies 18,000 households with electrical energy and 8,600 households with heat.
Waste incineration plant (MHKW)
The waste incineration plant was built between 1974 and 1976. At that time it consisted of two ovens and could burn 4-5 tons of garbage per hour. An expansion took place in the years 1980 to 1983. The entire system was comprehensively modernized from 1994 to 1996 for almost 85 million euros. Filters, turbines and other technical components were replaced. Household, bulky and commercial waste from the district of Lindau, the Oberallgäu, the city of Kempten and currently also parts of the waste from the districts of Ravensburg and Ostallgäu is recycled. The catchment area has about 257,000 inhabitants. The bunker for waste storage has a capacity of 1,500 tons. The electric generator converts the energy into 7.2 megawatts of electrical output, which at 8,000 hours per year produces 57.6 million kWh of energy (electricity for around 16,000 four-person households). The waste heat is used in the district heating network, as with the wood-fired power station. Every year around 10,000 to 15,000 tons of slag are issued as waste. This residue is disposed of at the Ravensburg landfill. The legal exhaust gas standards according to the 17th Federal Immission Control Ordinance are undercut by an average of 97%.
Wood-fired thermal power station (HHKW)
The wood-fired thermal power station is supplied with wood residues from forestry and industry. The waste wood is stored on 6000 m², the outdoor storage has a share of 5000 m² and a capacity of 10,000 m³. The garbage bunker has an area of 1000 m² and a volume of 2400 m³. The furnace has a throughput of 7 t / h, is 8 meters high, has a volume of 120 m³ and a combustion temperature of 850 to 1100 ° C. The steam has a temperature of 380 ° C and a pressure of 25 bar. The turbine has a speed of 12,500 rpm and an output of 2,600 kW. The 60 meter high chimney gives off exhaust air at 140 ° C. After burning out, around 10 kg of ash remain from one ton of wood. The plant was put into operation in 1998.
District heating
The pipeline network extends 36 km below the city and conducts heat from the industrial and commercial area to the city center of Kempten. Mainly public buildings such as the Kempten University of Applied Sciences or the Kempten Vocational School Center are supplied , but also private houses. According to the operator, 29,000 tons of carbon dioxide are saved annually compared to heating with heating oil or natural gas . If the thermal energy of the waste incineration plant is insufficient, especially in winter, the "peak load heating center", a block heating unit , is switched on. This burns heating oil and has a thermal output of 45 megawatts. On average, this system is used 1,800 hours a year.
