天然气高效利用途径分析

比较分析了天然气分别作为民用燃料和锅炉燃料、直燃空调燃料、联合循环发电以及区域能源站燃料等几种利用途径的优缺点。其中着重介绍了电、热、冷三联产的节能原理，国外区域能源站迅速发展的有关情况，以及国内区域能源站和电、热、冷联产技术发展状况。结果认为，天然气联合循环以及天然气区域能源站是高效利用的最佳途径，并指出天然气区域能源站的顺利发展需要政策的支持。

ANALYSIS ON THE WAY OF EFFICIENT GAS UTILIZATIONL 1)

The advantages and disadvantages are analyzed for natural gas to be residential fuel, boiler fuel, air-conditioner fuel by direct combustion, joint cycle power generation, and fuel of regional energy stations. The energy-saving principle of joint power generating, heating and refrigerating operation is explained emphatically. Also it is introduced the situation of regional energy stations developing rapidly abroad, and the developing situation of regional energy stations and joint power generating, heating and refrigerating operation technology at home. It is thought the joint cycle and the regional energy stations are the best way to utilize gas efficiently. Also, it is pointed out policy support is needed for smooth development of regional energy stations.
