Tofu-lees combustion heater

Japanese Patent JP6132414

B2

PROBLEM TO BE SOLVED: To provide a bean curd refuse combustion heating device capable of efficiently burning bean curd refuse fuel and efficiently using thermal energy by a simple device.SOLUTION: A bean curd refuse combustion heating device has a combustion furnace 26 for burning solid fuel having bean curd refuse as a main component, and a combustion chamber 24 for housing the combustion furnace 26 in the inside. The device includes: an air blower 42 sending 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 branched from the air supply main pipe 44 and sending air to the combustion furnace 26. Furthermore, the device includes: an air duct 46 connected with the air supply main pipe 44; a heat exchanger 28 connected to the air duct 46 and fixed to above the combustion chamber 24; a heat exchange pipe 52 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 is heat-exchanged with heat such as combustion gas with the heat exchange pipe 52 and is sent to the hot air pipe 54.SELECTED DRAWING: Figure 1
