Title: Simmering district heat storage system KW

To the Vienna continuously generated heat from household waste and hazardous waste burning, biomass power plants and cogeneration plants make optimal use, planning, Wien Energie GmbH, a district heating system memory set up. By a district can store a temporal decoupling between heat production and heat consumption can be achieved. By this measure, the use of natural gas or oil-fired peak boiler minimized to optimize the use of CHP and thus CO2 emissions are further reduced for Vienna (up to about 20,000 t / year). Furthermore, future days may peak during the summer months, which result from the use of district cooling purposes ("cold out of heat"), are covered by this project without the use of peak boilers.
