FIELD: power industry. ^ SUBSTANCE: automatic control and management device of gas burner includes gas line with two safety-shutoff valves in-series installed on it, bypass pipeline with pressurising and throttle valves installed on it, which are installed parallel to the first safety-shutoff valve; at that, pipeline of igniter with ignition valve and discharge pipeline with safety valve have common connecting point to gas line and bypass pipeline. Throttle valve is installed on gas line after the second safety-shutoff valve; igniter with spark discharging device is connected at ignition pipeline outlet through flexible hose, as well as air damper and control assembly the outputs of which are connected to control inputs and information outputs of all valves, throttle valve and damper, to input of igniter spark discharging device, gas pressure sensors in gas line and at burner nozzle inlet, air pressure sensors and sensors of available igniter flame and burner flame are introduced. ^ EFFECT: excluding the possibility of micro explosion formation at automatic burner lighting-up and providing automatic control of its heat power in operating range at constant maintenance of minimum content of hazardous substances in flue gases. ^ 1 dwg |
