Internal Circulation Fluidized Bed Boiler “ICFB”, which has been developed by KAWASAKI, is capable of firing various types of fuels, such as refuse derived fuel and wastes including corrosive components. The fluidized bed of ICFB is divided into “Combustion Cell” and “Heat Recovery Cell” by using “Double Partition Wall” and the bed material circulates internally by the differential air flow of each cell. The ICFB which has been supplied to Jeonju Paper Corporation (Jeonju City in Korea) is 131 t/h of steam generation by waste wood firing, that is the maximum capacity of ICFB, and electric power generation of 33 MW has been verified. The ICFB can substantially make a contribution to the effective utilization of renewable energy (woody biomass) and CO2 reduction.
