Abstract

PURPOSE:To enable simultaneous detection of the density of oxygen and the combustible gas which is the cause of black smoke in exhaust gas by providing an oxygen concentration detector and a combustible gas detector in a flow dividing pipe through which the exhaust gas absorbed to an air ejector is returned again to the main flow pipe. CONSTITUTION:The exhaust gas discharged from a combustion furnace is absorbed by the air ejector 1 and flows through the main flow pipe 2. By the action of the thermal convection accompanying heating of the oxygen concentration detector 7 provided in the flow dividing pipe 4 and of the differential pressure due to a flow dividing pipe 11 the exhaust gas flows into the flow dividing pipe 4. In the flow dividing pipe 11 are provided a filter 15 composed of ceramic, fibers and the like removing dust etc. in the exhaust gas and the combustible gas detector 12. By this constitution, simultaneous and continuous detection of the concentration of oxygen and that of combustible gas in the exhaust gas is made possible, thereby the generation of black smoke causing air pollution is controlled in automatic combustion control of boilers of a heat power plant and various combustion furnaces and thus stable combustion of low oxygen concentration can be performed.
