FBCCOMPACT WATERTUBE FLUIDIZED BED BOILER

Hamada Boiler continues to develop small and medium size of Fluidized Bed Boiler to meet requirement of many industries in the region. DF series use the most popular model "D" boiler body as a main pressure vessel so that the common spare parts with widely distributed D model will make maintenance easy. Moreover, all D-model already operating in many countries whether fixed grate type or chain travelling grate type can be converted to DF model by constructing fluidized bed combustion chamber just below the main D model boiler body and connect the two components by up going tube and down commer tube. In fact, to date, many chain grate D model boilers have been converted to fluidized bed system in Indonesia.
