Startup and operation of the Kauttua 200,000 lbs of steam per hour cogeneration Ahlstorm circulating fluidized bed combustion
The Startup and operation of a 200,000 lbs of steam per hour cogeneration system located in Kauttua, Finland, is described. The contract for this plant was let in September 1979. This is the world's largest commercial circulating fluidized bed combustion system installed and operating in an industrial plant. Wood, peat and coal are burned as fuel. Boiler components which are unique to the circulating bed system are the combustion chamber, hot cyclone and recirculating valve and feed system. All other systems and components are of conventional coal-fired boiler design and manufacture. The combustion chamber consists of a lower combustion section with an air distribution grid and a bottom ash removal system incorporated in the design. The hot gas including the entrained solids is exhausted to a hot cyclone collector which has a ceramic abrasion resistant liner and thermal insulation. Most of the unburned solids and the bed material (sand or limestone) is recirculated through the special design non-mechanical valve back into the combustion chamber.
