FIELD: production plant equipment.
SUBSTANCE: according to proposed method of ventilation of industrial plant, contaminated air is sucked in by local suction devices and directed into assembly air duct of exhaust system, is passed into underground no-pressure system wherefrom it is delivered into suction air duct of boiler plant blow fan. Invention provides reduction of power, capital outlays and service expenses for ventilation of industrial plant owing to dispensing with special fans for evacuation of exhaust air from production shops into atmosphere, thermal neutralization of harmful organic compounds in contaminated air in boiler furnaces and recovery of excess liberated heat from production equipment of ventilated shops.
EFFECT: reduced power losses.
