COMBINED HEAT AND POWER SYSTEM WITH HEAT RECOVERY STEAM GENERATOR FOR GREENHOUSE CARBON DIOXIDE ENRICHMENT

摘要

PURPOSE: A cogeneration system with a heat recovery system for the carbon dioxide enrichment of a greenhouse is provided to enable additional power generation when the heating of a greenhouse is not required by powering a steam turbine generator. CONSTITUTION: A cogeneration system with a heat recovery system for the carbon dioxide enrichment of a greenhouse comprises a combustion generator(110), an exhaust gas shift switch(130), first and second exhaust gas supply lines(L11,L12), first and second heat exchangers(130,135), a heating line(L21), a heat recovery line, a steam turbine generator(136), and first and second electrical lines(L31,L32). The combustion generator produces electricity using the combustion of a combustor. The exhaust gas shift switch switches the route of exhaust gas exhausted from the combustion generator. The first heat exchanger is coupled to the first exhaust gas supply line and heats heating water using the heat of the exhaust gas.
