Valmet's circulating fluidized bed boilers for a flexibl

The more challenging the fuel, the more flexibility Valmet's circulating fluidized bed (CFB) boiler shows. It has evolved from a coal-only boiler to combusting biomass and anything in between. One of the component design highlights is the first water-cooled cyclone built in 1985, and since 1995 a membrane cyclone has been included in

Heat transfer in a large-scale circulating fluidized be

Abstract. Heat transfer of a furnace in a large-scale circulating fluidized bed (CFB) boiler was studied based on the analysis of available heat transfer coefficient data from typical industrial CFB boilers and measured data from a 12 MW e, a 50 MW e and a 135 MW e CFB boiler. The heat transfer of heat exchanger surfaces in a furnace, in a steam/water cooled cyclone, in an external heat
