对AE94.3A型燃气轮机燃气-蒸气联合循环热力系统平衡进行研究发现，与同类型、同等级不同型号机组比较，AE94.3A型联合循环机组余热锅炉的排烟温度较高，排烟余热仍有进一步利用的空间。通过设计优化扩大省煤器受热面，回收烟气余热加热给水，驱动热水型溴化锂制冷机制冷，用于机组满负荷调峰时的压气机进气冷却或厂房及办公区域空调供冷，可起到改善燃气轮机联合循环的运行性能，实现能源梯级利用，提高能源利用率和机组运行经济性的作用。

AE94.3A gas turbine for gas - steam combined cycle thermal power system balancing study found that compared with the same types, different types of units, the higher exhaust temperature of Hrsg for combined cycle units, Exhaust heat there is still room for further improvement. By designing optimized expansion of economizer heating surface, flue gas heat recovery water, drive-hot water-lithium bromide chiller refrigeration, for turbine full load cycling of compressor inlet air cooling or plant and Office air conditioning and cooling, can serve to improve the performance of gas turbine combined cycle, energy cascading utilization, Role in improving energy efficiency and economic operation of the unit.
