摘要

根据厦门燃气电厂实际情况，提出了一种LNG热电冷三联产节能方案。在假设条件下，分析并计算了该方案下的系统能源利用率、运行经济性及节能潜力。结果表明：该节能方案冷电、热电系统能源利用率分别可达89.2%和82.8%，联产系统总能利用率超过80%;而且供冷系统的运行费用较低，投资回收期小于5年，具有明显的经济效益和较大的节能潜力。

Abstract

An energy saving project for the LNG-CCHP system in Xiamen natural gas power plant is put forward according to the basic data of this power plant.The system primary energy ratio，operation economics and energy saving potential are analyzed and calculated under some assumptions.The results show that the system total energy efficiency of this project is higher than 80%，with the energy efficiency of cooling-power system and heating-power system up to 89.2% and 82.8% respectively.Moreover，the operation costs for cooling system are fewer and the investment recovery period is less than 5 years.Therefore，the proposed LNG-CCHP system has great economic benefits and energy saving potentialities.
