GAS ANALYZER AND COMBUSTION CONTROLLER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To realize combustion control with a higher accuracy by continuously sampling an exhaust gas at an outlet of an incinerator or the like. SOLUTION: Heat resisting porous tubes 5 and 6 are provided at tip parts of sampling tubes 3 and 4 to analyze the exhaust gas introduced from the porous tubes 5 and 6 with an analyzer 11. The dusting operation at one porous tube 6 by the closing operation of a first exhaust gas solenoid valve 12 and the dusting operation at the other porous tube 6 by the closing operation of a second exhaust gas solenoid valve 13 are alternately performed at a fixed interval thereby accomplishing continuous gas analysis and dust removing operation.
