Abstract

Additional air is added to the flow in quantity and temperature adequate to accomplish complete combustion of the carbon monoxide. Temperature difference before the air addition and after complete combustion is measured. The device comprises a probe with the above channel; means for supply of a quantity of air sufficient for the carbon monoxide complete combustion, and at least two temperature sensitive detectors, placed up and downstream from the air addition point. The detectors (thermocouples) are connected to a temperature difference measuring circuit.
