滨海电厂水电联产的技术经济分析

Technical and Economic Analysis of Hydropower Generation in the Coastal Power Plant

采用国产低温多效海水淡化设备替代电厂冷凝器的方式,使汽轮机与海水淡化设备进行耦合,从而实现水电联产。通过对汽轮机参数变化引起发电量的减少和造水产生效益的比较分析,从技术上探讨了水电联产方案的可行性。该方案具有一定的经济优势,并为沿海地区淡水资源的匮乏提出了一个解决思路。

The coupling of steam turbine and the seawater desalination device by using the domestic low-temperature multi--effects desalination equipment is applied instead of the power plant condenser, and so water and electricity cogeneration is realized. By comparing the reduced power caused by the change of the steam turbine parameters with the benefit from water production, the paper discussed the feasibility of the water and electricity e^generation. The scheme has a certain economic advantage, and presents a solution for coastal region where being suffered from freshwater shortage.
