摘要
电厂循环冷却水中含有大量的低位热能,采用热泵技术,可以将这部分热能回收利用.结合实际,分析了热泵技术在热电厂余热利用中的实际应用,通过此项技术,可使电厂节能率达32.8%,年节省蒸汽折算效益达2580万元,静态成本回收期仅为2.4 a;同时每年冬季可节省标煤16360 t,大量减少了有害气体的排放,可以有效地实现电厂的经济效益与节能减排.
There is a large amount of low heat energy in circulating cooling water oftherrnal power plant. It can be recovered by the heat pump technology. This paper analyses the practical application of heat pump technology in thermal power plant waste heat utilization. The energy-saving rate of this power plant is up to 32.8%. The conversion cost of saving steam is 25.8 million yuan per year. The static payback period is only 2.4 years. The saving standard coal consumption is 16360t per year in winter days, which can reduce the emission of harmful gases at the same time. It can effectively realize the economic benefits and energy saving and emission reduction of thermal power plant with the technology.
