Technology Brief |
The power plant in the Kymijaervi power plant area is based on the CFB gasification technology equipped with innovative gas cooling and cleaning system before combusting the product gas in a specially designed gas fired boiler. Valmet delivered the CFB gasification process, plus gas cooling and cleaning, steam boiler and flue gas cleaning system. The SRF is gasified at 850-900 °C in two CFB-gasifier units (2x80 MW) and converted into product gas, the gas is then purified and the resulting clean ecogas is combusted in an ordinary natural gas boiler. The raw material of the SRF is energy-containing waste.In the gasification of SRF, impurities, that cause boiler corrosion, are transferred to the product gas. The product gas is cooled from 900 degrees to about 400 degrees so that materials causing corrosion turn from gas into solid particles. Then, the solid particles can be filtered out so that the resulting gas is clean. The total fuel input of the plant is 160 MW; the power plant produces 50 MW of electricity and 90 MW of district heat for the city of Lahti.
