北京四大燃气中心新型联合循环机组性能参数研究

Study of Performance Parameters of New Combined Cycle Units in Beijing's Four Gas Turbine Centers

对近期北京投产以及在建的联合循环电厂的新型燃气轮机进行了详尽的研究,分析并对比了主要性能指标的变化情况以及各家机组的新技术特点。并且对已经长期稳定运行的典型联合循环机组的经济性进行了计算。结果表明,北京近几年投产的联合循环机组设计制造技术已经接近国际先进水平。燃气-蒸汽联合循环机组对于降低煤耗;提高能源利用效率;减少二氧化碳、硫化物排放有突出作用。

The research was carried out on new steam-gas combined cycle plants of Beijing. The changes of parameters and technology improvements was listed out. And the calculations on the typical combined cycle units which has already been used to generate electricity for long time was carried out. The results show that the combined cycle unit＇s design and manufacturing technologies are close to the international advanced level. The gas-steam combined cycle unit has the exeellences on saving energy and increasing energy utilization ratio.
