FUEL TRANSFER DEVICE OF A CFBC BOILER FOR BURNING RDF AND RPF CAPABLE OF PREVENTING THE CONGLOMERATION OF RDF AND RPF

摘要

PURPOSE: A fuel transfer device of a CFBC(Circulating Fluidized Bed Combustion) boiler for burning RDF(Refuse Derived Fuel) and RPF(Refuse Plastic Fuel) is provided to easily convert waste fuel into energy.;CONSTITUTION: A fuel transfer device of a CFBC boiler for burning RDF and RPF comprises a fuel storage tank, a transfer screw, a raw material expanding pipe, and an air supply pipe(400). A stirrer(102) of the fuel storage tank consecutively moves RDF and RPF(101). The transfer screw comprises a forward screw(203) and a reverse screw(204) and transfers the RDF and RPF to the raw material expanding pipe. The raw material expanding pipe eliminate the compressive force of the RDF and RPF compressed by a fuel expanding duct(301) and discharges the RDF and RPF through a fuel discharge pipe(302). The air supply pipe prevents the RDF and RPF from being stopped in the raw material expanding pipe.;COPYRIGHT KIPO 2012
