REGENERATIVE COMBUSTION DEVICE AND PYROLYSIS PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a regenerative combustion device and a pyrolysis processing method capable of preventing a heat storage body from erosion by curbing consumption of auxiliary fuel through means which can be easily installed to an existing facility without requiring a huge amount of facility investment and reservation of an installation place for an additional facility.SOLUTION: A regenerative combustion device comprises: a combustion chamber 4 which burns processing object gas; an auxiliary fuel supply path 16 which introduces auxiliary fuel into the combustion chamber 4; at least a pair of heat storage chambers 3 which store heat storage bodies 12 and are communicated with the combustion chamber 4; a fan 7 which transfers the processing object gas to the combustion chamber 3; a rotary type selector valve 18 which switches transfer directions of the processing object gas to the heat storage chambers 3; an auxiliary fuel flowmeter 17 which detects consumption of auxiliary fuel in the combustion chamber 4; a discharge port thermometer 20 which detects a temperature of the processing object gas discharged from the heat storage chambers 3; and control means 21 which controls a gas transfer amount with the fan 7 on the basis of detection results of the auxiliary fuel flowmeter 17 and the discharge port thermometer 20.
