摘要
近年来,我国天然气管道迅速发展,PGT25+型燃气轮机获得广泛应用。这类机组冬季运行时进气系统会发生不同程度的结霜现象,对燃气轮机安全运行造成严重影响。由于存在设计缺陷,制造商自带的防霜装置不能完全解决结霜问题。对燃气轮机进气系统结霜热力学过程进行了深入研究,通过分析压降、相对湿度对结霜过程的影响,自主设计研制了抽气式进气加热装置,消除了燃气轮机进气系统的结霜现象。结果表明,该装置操作界面友好,抽气量小于2%,功率损失小于7%,取得了良好的应用效果。研究成果具有广阔的推广价值。
In recent years, the natural gas pipelines have been developed rapidly in our country, the PGT25 ＋ gas turbines have been widely applied. In winter, varying degrees of frosting phenomena may occur in the air intake system of such unit, and seriously affecting the safety operation of gas turbine. Due to the design defects, the anti-frost device provided by manufacturer is unable to fully solve the problem. Depth research of the thermodynamic processes of frosting of intake system in gas turbine is conducted, through analyzing the influences of temperature drop, relative humidity to the frosting process; the suction-type intake air heating system is designed to eliminate the frosting phenomena. The results indicate that the device is equipped with operation friendly interface, the suction capacity is less than 2% ; power loss is less than 7% , it possesses excellent applicable effect, and the achievement of research is worth to be popularized.
