INFRARED COMBUSTION DEVICE

摘要

PROBLEM TO BE SOLVED: To solve a problem of occurrence of back fire fundamentally at an infrared combustion device, stabilize combustion flame and eliminate ununiformity combustion when a flame hole part is arranged under high-density state.SOLUTION: An infrared combustion device 1 comprises an infrared radiation plate 10 with a flame hole segment 11 passing through its thickness direction and having a flame port 11A being opened at the front surface side and open hole 11B opened at the rear surface side; and a gas supply body 20 having a gas supply passage 21 for supplying fuel gas. The gas supply body 20 comprises a gas injection part 22 protruded into the open hole 11B to inject fuel gas passed through the gas supply passage 21 into the flame hole segment 11. An air flow passage Ga for supplying combustion air to the flame hole segment 11 is formed at a clearance between the gas supply body 20 and the rear surface side of the infrared radiation plate 10. The air flow passage Ga has a side air flow passage Gb formed along a side part of the gas supply body 20 and a crossing air flow passage formed at the surface of the gas supply body 20 and linearly crossing between the side segments of the gas supply body 20.
