More Information
Summary:PURPOSE: A powdered fuel combustion apparatus is provided to secure optimal combustion efficiency by control residence time of second powered fuel in a furnace. CONSTITUTION: A powdered fuel combustion apparatus comprises a furnace(10), a mixed coal feeder(100), first and second fuel supply sources(30, 40). The furnace burns powdered fuel. The mixed coal feeder comprises a first fuel supply member(110) of hollow pipe type and a multi-layered pipe type second fuel supply member(120). The fuel discharge port of the first fuel supply member is connected to the inner space of the furnace. First and second fuel feeders connect the first and second fuel supply sources and the furnace. The second fuel feeder is composed of a second fuel supply pipe and a cooling pipe. The cooling pipe comprises a cooling water inlet port and a cooling water outlet port and covers the exterior of the second fuel supply pipe.
