BEAN CURD REFUSE FUEL, BEAN CURD REFUSE FUEL PRODUCTION APPARATUS, AND BEAN CURD REFUSE COMBUSTION HEATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide bean curd refuse fuel, a bean curd refuse fuel production apparatus, and a bean curd refuse combustion heating device capable of efficiently burning bean curd refuse fuel and using thermal energy efficiently by a simple device.SOLUTION: A bean curd refuse combustion heating device has: a combustion furnace 26 that burns solid fuel having bean curd refuse as a main component; and a combustion chamber 24 that houses the combustion furnace 26 therein. The device comprises: an air blower 42 that sends air for combustion of the combustion furnace 26 and air for heating; an air supply main pipe 44 connected to the air blower 42; and an air supply pipe 40 which is branched from the air supply main pipe 44 and sends air to the combustion furnace 26. The device comprises: an air duct 46 to which the air supply main pipe 44 is connected; and a heat exchanger 28 which is connected to the air duct 46 and fixed above the combustion chamber 24. The device also comprises: a heat exchange pipe 52 which is provided in the heat exchanger 28 and communicated into the air duct 46; and a hot air pipe 54 communicated into the heat exchange pipe 52. Air sent from the air duct 46 exchanges heat with heat such as combustion gas by the heat exchange pipe 52 and is sent to the hot air pipe 54.
