摘要:

为进一步提高燃气-蒸汽联合循环机组的能源利用率、满足更高的供热需求,对机组原供热方案进行改造。以某电厂9F级燃气-蒸汽联合循环机组为例,描述了机组实际运行情况,分析了3种供热改造方案的优缺点,并对改造后机组的参数进行了分析计算。计算结果说明改造提高了机组供热性能、热电比,并降低了发电气耗,可为同类型机组改造提供参考。

Abstract:

In order to further improve the energy utilization rate of the gassteam combined cycle units and meet a higher heating demand, the original heatsupply scheme for units need to be modified. Taking 9F gassteam combined cycle units in a power plant as an example, the actual operation of the unit after modification was briefly described. The advantages and disadvantages of three heating modification schemes were analyzed in detail. The parameters after modification were analyzedand the results show that the modification has improved the performance of heat supply and ratio of heattoelectricity, and reduced gas consumption for power generationwhich provides reference of the modification for units of the same type.
