近20年来,燃气轮机和蒸汽燃气联合循环装置在主要的资本主义国家以及石油和天然气为燃料主要成分的发展中国家的动力工程中,已占据稳固地位.美国居首位,燃气轮机的装机容量为60000MW以上.沙特阿拉伯居第二位,装机容量近20000MW.全世界运行中的动力燃气轮机装置有13000台以上.总功率约200000MW.除少数例外,目前生产的所有动力燃气轮机装置都采用简单热力循环.一些主要公司批量生产专门用于动力工程的单轴燃气轮机,其功率为35—150MW,燃气初温为1100℃.其中功率较大的燃气轮机的技术指标列于表1.60MW以下的功率是通过减速齿轮箱由燃气轮机
For nearly 20 years, gas turbines and steam gas combined cycle units have enjoyed a solid position in power engineering in major capitalist countries and in developing countries where oil and natural gas are the major constituents of fuel. The United States ranks first with gas turbine installations of 60,000 MW Saudi Arabia ranks second with installed capacity of nearly 20000 MW. There are over 13,000 powered gas turbine installations operating worldwide, with a total power of about 200 000 MW. With a few exceptions, all current utility gas turbine installations are equipped with simple thermodynamic cycles. Some Major companies mass-produce single-shaft gas turbines specifically for power engineering with a power of 35-150 MW and a gas initial temperature of 1100 ° C. The technical specifications of the more powerful gas turbines are listed in Table 1. The power below 60 MW is transmitted through a reduction gear box By the gas turbine
