美国内布拉斯加州林科电力系统对通用电气公司的MS7001B型燃气轮机执行了一个改进计划——改进进口冷却系统并改进其进口导叶。在电力高峰时,让通过冰箱的冷却水在压气机进口的盘管内循环流动冷却进气并降低其湿度,从而增加空气密度,使通过发动机的空气质量流量增加。结果在38℃环境温度下,可使燃气轮机的输出功率从53MW净增到67MW,相当于输出功率增加25%,热耗率降低4%,附加装置(贮冰箱、制冰设备、热交换盘管等)的费用约为165美元/千瓦。
Lincoln Power Systems, Nebraska, USA, implemented an improvement plan for General Electric’s MS7001B gas turbine - improving the inlet cooling system and improving its inlet guide vanes. During peak power, the cooling water passing through the refrigerator circulates through the coil of the compressor inlet to cool the intake air and reduce its humidity, thereby increasing the air density and increasing the air mass flow through the engine. The result was a net increase of gas turbine output from 53 MW to 67 MW at 38 ° C ambient temperature, equivalent to a 25% increase in output power and a 4% reduction in heat rate, with additional equipment (storage fridges, ice makers, heat exchange coils Etc.) costs about $ 165 / kW.
