FLUIDIZED BED WATER PIPE BOILER DIVIDED TYPE

摘要

FLUIDIZED BED WATER PIPE BOILER DIVIDED TYPE A fluidized bed water tube boiler comprising a fluidized bed combustion section including a fluidized bed formed from a continuous water tube wall, a free-board section for burning volatile components produced in the fluidized bed combustion section, and a convective heat transfer section comprised of a steam drum and a water drum connected to the downstream side of the freeboard section through water tubes for recovering heat from combustion exhaust gas; wherein the fluidized bed combustion section and the freeboard section are formed as separable modules which are connected to each other, and circulation of a boiler water between the fluidized bed combustion section and the convective heat transfer section is separated from that between the freeboard section and the convective heat transfer section.
