| Abstract: | 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. |
