FIELD: ventilation.
SUBSTANCE: invention is meant for ventilation and may be used in the service equipment of buildings in production facilities. The ventilation system comprising local exhaust of air with contaminants, an air duct connecting the local exhausts with a suction intake of a boiler forced-draft fan; the system is equipped with a temperature sensor connected to a buzzer, with a boiler forced-draft fan and with an actuator for operating a final control element. The ventilation system air duct is provided with a gas burner used for periodical cleaning of stained organic deposits of contaminants from the air duct by annealing the air duct walls made of heat-resistant steel.
EFFECT: improving the reliability and economical efficiency of a production facility ventilation system.
