摘要
西气东输天然气管道沿线经历了不同的地理环境和气候条件。冬季的早上,在西北地区燃气轮机的进气滤芯表面常常出现严重的结霜,进气阻力增大,严重影响了燃气轮机的正常运行。通过对燃气轮机随机配套的防结冰系统进行了研究和改造,并在西气东输管道燃气轮机上进行试验,取得了良好的效果,解决了燃气轮机进气滤芯表面结霜的问题。经过近5年来的推广应用,取得了可观的效益。
The geographical and climate conditions are different along the West-East natural gas pipelines. In winter morning, a lot of frost adhered to the surface of inlet filters of gas turbine in the north-western China. It caused the differential pressure of filters to in- crease greatly, which seriously affected the normal operation of gas turbine. We carried out a research on anti-ice system of gas tur- bine, and upgraded the anti-ice system. Operation showed that the upgrade was successful and got our previous intention. The frost problem got solved completely. After 5 years＇ application, a considerable benefit has been gained.
