High-performance regenerative burner by four-way switching valve and regenerative combustion method using the same

摘要

A high efficient heat storage burner by a four-way switching valve, and a heat storage combustion method using the burner are provided to make the temperature of a furnace uniform through alternate combustion of burners, to maximize heat recovery through direct heat exchange of exhaust gas and combustion air by switched combustion, to downsize equipment, and to enable reduction of a heating furnace through improvement of heat transfer efficiency. In a high efficient heat storage burner by a four-way switching valve(5), and a heat storage combustion method using the burner, a heat storage body is installed in burner equipment, two burners(1,2) are formed in pairs, and the four-way switching valve is installed in the middle of the burner equipment to execute repeated combustion work. One of the burners stores heat by the heat storage body while the other of the burners supplies a heat source through combustion for predetermined time, and opposite working is executed by the four-way switching valve after predetermined time.
