带补燃联合循环机组性能试验方法研究

Performance Test Procedure of Combined Cycle Unit with Supplementary Firing

海外带补燃联合循环机组项目越来越多,性能试验如何执行成为难题。结合带补燃联合循环系统的设计及运行特点,并依据ASMEPTC46标准,分析带补燃联合循环机组性能试验边界、修正曲线绘制方法、性能试验流程等,得到不同试验方法的优缺点,最终提出适用于带补燃的同期或分期建设联合循环系统的性能试验方法。

Nowadays, more and more combined cycle units with supplementary firing are applied in oversea market, but it is difficult to carry out performance test for these units. Combined with the design and operation features of combined cycle units with supplementary firing, the boundary of performance test, drawing method of correction curve and procedure of test for this type of unit were analyzed based on ASME PTC46,and then the advantages and disadvantages of different performance test methods were gained. Finally, the performance test procedure was proposed for combined cycle system with supplementary firing built at the same time or by stages.
