FIELD: recording adjustable magnitude proportional to combustion temperature. SUBSTANCE: descending waste gas exhaust passage is provided with infrared metering device made in form of infrared pyrometer for measuring the waste gas temperature. Such position of pyrometer excludes effect of radiation of hot combustion layer of flame. Adjustable magnitude which depends on temperature may be used for direct or indirect action on combustion process. In preferable version, adjustable magnitude is used for action on delivery of fuel and speed of motion of fire grate; amount of primary air is acted on by adjustable magnitude of steam mass flow. EFFECT: enhanced efficiency. 10 cl, 1 dwg
