1985年7月24日,我厂召开了“燃气蒸汽联合循环”的情况介绍会。燃气蒸汽联合循环是一种逐级利用热能的有效方式。采用这种方式以后,燃料的热能可以在几个不同的温度等级内,逐级得到利用,大大提高了热效率。目前,燃气蒸汽联合循环在美国、日本等发达国家得到推广应用。我国对这项技术的应用也已开始,例如北京市东郊电站已经使用燃气蒸汽联合循环机组(主要用于补充用电高峰期间的电 July 24, 1985, I plant held a “gas steam combined cycle” briefings. Gas-steam combined cycle is an effective way to use heat energy level by level. In this way, the thermal energy of the fuel can be used step by step in several different temperature grades, greatly improving the thermal efficiency. At present, gas steam combined cycle in the United States, Japan and other developed countries have been widely used. The application of this technology in China has also started. For example, the power plant in the east suburb of Beijing has already used gas-steam combined cycle unit (mainly used for supplementing electricity
