妈湾电厂对前海深港合作区蒸汽制冷供汽研究

Research on Steam Refrigeration Supply for Qianhai Shenzhen Hong Kong Cooperation Zone by Mawan Power Plant

本文以前海深港合作区项目为例,通过对该区域热负荷情况进行分析,研究出经济合理、切实可行的蒸汽制冷供汽方案。研究结果表明:采用蒸汽溴化锂制冷,运行费用低,可节约0.2055元/k Wh,同时在该制冷方式下,将电厂生产中产生的大量热能资源用于溴化锂机组制冷用蒸汽,形成热(冷)电联供系统,不仅能提高热效率、改善区域环境,还能实现能源梯级利用以及节能减排,经济、节能环保以及社会效益显著。

This article takes the previous Haishen Hong Kong Cooperation Zone project as an example and analyzes the heat load situation in the area to study an economically reasonable and feasible steam refrigeration and supply scheme.The research results show that the use of steam Lithium bromide refrigeration can save 0.2055 yuan/kWh with low operating costs.At the same time,under this refrigeration mode,a large amount of thermal energy resources generated in the production of the power plant will be used for the refrigeration steam of the Lithium bromide unit to form a heat(cooling)power supply system,which can not only improve the thermal efficiency,improve the regional environment,but also achieve energy cascade utilization,energy conservation and emission reduction,and achieve significant economic,energy conservation,environmental protection and social benefits.
