ABSTRACT

The waste combustion plant at Duiven was put into operation in 1975. In 1986 one of three furnaces was equipped with a boiler instalation for the production of hot water, to be used in a district heating system. At the moment, a new energy recovery project is nearing completion. In April 1990 a steam boiler will be put into service, which utilizes the heat from one of the other furnaces. At the same time, an Integrated Energy System (IES) will be made. In this congeneration system the maximum heat from both boilers is utilized directly for heat supply to the district heating system. The heat that can not be used for this purpose is converted into electricity by means of a HP/LP turbine-generator unit. In order to minimize the emission of potentially harmful flue gas substances all 3 furnaces will be provided with a wet flue gas cleaning system.
