FIELD: analysis of gaseous atmosphere. SUBSTANCE: facility estimating concentration of combustible gases in oxygen- carrying atmosphere is intended, for instance, for production areas of petroleum and petroleum refining plants, of thermal power plants, of chemical plants and so on to prevent potential explosion-risky situations. Technical result of invention lies in increased accuracy of determination of concentration of combustible gases in oxygencontaining atmosphere by maintaining value of current pulse of generator in specified limits, in securing possibility of supply of pulses of different configuration to thermal catalytic element and in estimation of concentration of individual substances with different physical-chemical properties by that. Facility estimating concentration of combustible gases in oxygen-containing atmosphere includes thermal catalytic element which output is connected to first input of controller which first output is connected to information display and which second output is connected to input of generator whose output is connected to input of thermal catalytic element. Output of generator is connected to input of thermal catalytic element through resistor which resistance Rel lies in limits from 0.5 to 1000 Ohm and to second input controller. EFFECT: increased accuracy of determination of concentration of combustible gases in oxygencontaining atmosphere. 1 dwg
