天然气冷热电联产运行模式的探讨

Discussion on Running Mode of Combined Cooling Heating and Power System with Natural Gas as Fuel

介绍了一种具有很高一次能源利用率的天然气冷热电三联产系统及其在国内外的应用情况;阐述了几种天然气冷热电联产系统的运行方式与特点,包括基于燃气机、燃气轮机、联合循环、斯特林发动机和燃料电池的冷热电三联产系统;分析了冰蓄冷技术在冷热电联产系统中的意义与作用;对近年来各运行方式的主要研究成果进行了总结与评述;根据国内外天然气冷热电联产系统的研究与应用现状,对未来的主要研究方向作了一些有益的探讨。

Introduced the combined cooling heating application status at home and abroad. Several nature and power （CCHP） system with natural gas as fuel and its gas fired CCHPs were introduced in running mode and peculiarity. They had the modes based on gas machine, gas engine, combined cycle, striling generator and fuel cell. The signification and function of ice storage technology in CCHP system were also analyzed. Based on these discussions and the research and utilization of nature gas fired CCHP in homeland and other countries, some advices were given on future research direction.
