| Technology Brief |
The gasifier at Kymijärvi power station is an atmospheric 60 MW CFB gasifier supplied by Amec Foster Wheeler. The gasifier was commissioned in early 1998 and has since then been in commercial operation. The operating temperature in the reactor is typically 800-1000 °C depending on the fuel and the application. The fuel is fed into the lower part of the gasifier above a certain distance from the air distribution grid. The product gas for combustion is led directly from the gasifier through the air preheater to two burners, which are located below the coal burners in the boiler. The gas is combusted in the main boiler and it replaces hard coal in a 360 MWth boiler producing power and district heat. The annual gasifier availability has been over 95 % in each year and the Lahti plant has clearly demonstrated that the technology is technically proven and is able to reduce the emission of CO2, SO2, dust and NOx compared to coal-alone combustion.
