ENERGY SAVING TYPE COGENERATION SYSTEM

摘要

A cogeneration system capable of saving energy is provided to improve heat exchange efficiency and to improve heat storage efficiency by using a heat collecting pipe lines. A cogeneration system capable of saving energy comprises a cogeneration unit(10), distributors(14,15), a circulation pump, a cooling tower(20), a hot water storage tank(40), and an auxiliary boiler(30). The distributors supply and re-circulate hot circulating water. The circulation pump circulates hot water forcedly. The cooling tower supplies cooling water for an engine to the cogeneration unit. The distributor, the circulation pump and the cooling tower are consecutively connected and forms a hot water circulating fundamental pipe. The hot water storage tank is installed between the distributors. A hot water supply pipe is extended to pass through the hot water storage tank. A hot water circulating pipe is additionally formed to share heat with the hot water supply pipe. A hot water heat supplementing pipe which is passing through the circulation pump and the auxiliary boiler, is formed at the hot water re-circulate distributor. A heat supplementing hot water circulation pipe heats up the hot water storage tank and supplies cooling water to the cogeneration unit, and supplements insufficient heat to the auxiliary boiler.
