GREENHOUSE HEATING APPARATUS Russian patent published in 2001 - IPC

FIELD: heat engineering. SUBSTANCE: apparatus has boiler, hipped roof greenhouse heating system connected to boiler, contact-type combustion product heat recovery unit, subsurface heating system, accumulating tank, air decarbonizer with evaporated product discharge branch pipe connected via pipeline to suction box of boiler blowing fan, two air heaters. Outlet branch pipe of one air heater is connected via pipeline through exhaust fan to channel for discharging exit combustion products into atmosphere and of other air heater to air decarbonizer. Apparatus is further provided with greenhouse gas distribution system connected via filter through pipeline to channel for discharging combustion products into atmosphere and is further connected via pipeline to carbon dioxide generator. Employment of air heaters allows economy to be increased by supplying heated air to decarbonizer to improve water degassing quality and increase blowing air temperature, as well as to slightly dry exit combustion product by mixing in hot air. EFFECT: increased efficiency by increased amounts of combustion products discharged through recovery unit, reduced productional costs and enhanced reliability in operation. 3 cl, 1 dwg
