摘要
热悬挂是燃气轮机在启动过程中比较严重的一种故障,主要原因是由于燃气轮机在启动升速过程中,排烟温度上升过快,与机组升速率不协调而造成压气机严重失速,即使再增加燃料量,也不能使机组正常升速。本文分析了西门子SGT5-4000F(4+)型燃气轮机在启动过程中出现热悬挂的原因,并根据原因逐步排除,最终使热悬挂问题得以解决。
Thermal blockage is an important fault in the start-up process of gas turbine. The main reason is that exhaust temperature rises too fast in process of gas turbine starting up, and the unit rate is discordant causing severe stall of the compressor. Even if fuel quantity is increased, the unit can not normal raise speed. This paper analyzes the reasons of the thermal blockage of the Siemens SGTS-4000F （4＋） gas turbine during the start-up process, and finally the problem is solved.
