FIELD: farming; greenhouses. SUBSTANCE: burner includes gas cock, electromagnetic valve with air temperature sensor, gas nozzle with adjustable plate for feeding the air to mixing chamber and fire tip which is made in form of pipe with holes located on one straight line; pipe is provided with bottom at its end. Ignition burner is mounted at the beginning of pipe; one end of thermocouple is located in zone of ignition burner; other end of thermocouple is connected with gas cock control mechanism. During operation, thermocouple opens gas cock admitting gas through holes-microjet burners; thus, gas is ignited. When gas is cut out, gas cock is closed.
