摘要
管道燃气轮机驱动压缩机组现场自带的防冰系统在运行过程中存在可靠性低,能耗大,燃机进气滤芯结霜、结冰等问题。为了对现有燃气轮机的压气机进口空气防冰装置进行改进与优化,结合理论计算与现场研究,设计出一种燃气轮机节能型进气防冰装置:通过做功后的燃气回流,加热燃气轮机进口空气实现防冰目的;通过引入手动阀门、引风机控制燃气回流量,代替原理较为复杂的自动阀门控温。改进后的经济性分析结果表明:与原装置相比,新设计防冰装置具有节能、控制系统简化、可靠性提高、防霜等优点,对提高管道压缩机组运行管理水平具有重要作用。
The anti-icing system attached to the gas turbine(GT) driven compressor set for pipeline on site has low reliability, high energy consumption, frosting and icing at the air inlet filter of the gas turbine, and other problems during operation. In order to improve and optimize the anti-icing system at the air inlet of existing GT-driven gas compressor set, a GT-driven energy-conservative air inlet anti-icing system is designed through theoretical calculation and field investigation. The system can work for anti-icing by heating the gas turbine through gas return after acting, with manual valve and induced draft fan to control the volume of gas return, instead of complicated temperature control process with automatic valve. The economic analysis of the improved system shows that, in contrast to original unit, the new anti-icing system is more advantageous for energy conservation, simplified control system, high reliability, and anti-frosting, and it is of great importance for upgrading the operation management of compressor sets for pipelines.
