FIELD: heating, burning. ^ SUBSTANCE: invention relates to heating engineering and can be used to purify gases of heat power plants, heating installations, industrial boiler houses and to utilise heat of these gases. An exhaust gas flue of a boiler furnace is equipped with an open-end metal casing of a low-temperature heater connected through a cyclone and filter purification system, a catalyst for carbon monoxide removal and through large-diameter heating manifold pipes with suction tubes of air inlet filters of internal combustion engine which provide for the necessary pressure difference and draught in the flue. The large-diameter pipes are laid in the heated ground under greenhouses and are selectively heat insulated leaving an air pocket over the pipes which is protected by perforated covers and closing hatches for dust removal. The low-temperature heater is connected to the high-temperature heater through the main closed pipe loop and to the manifold pipes for heating greenhouse rooms through an additional closed loop parallel to the main one, the high-temperature heater is made as a water jacket of a cooling system of an internal combustion engine. The flue gases are finally purified from harmful chemical compounds in combustion chambers of internal combustion engines by thermal incineration. ^ EFFECT: complete flue gas purification, increasing efficiency of heating installations due to the utilisation of flue gas heat. ^ 2 cl, 1 dwg |
