摘要
某型船用燃气轮机由冷态起动至慢车工况,经历电机起动、空气压缩、点火燃烧、涡轮升速等过程。起动过程由静态到动态,由电能和燃油的化学能转化为涡轮的机械能,是一个发生急剧物理化学变化的过程,同时也是发动机最容易发生故障的过程。在分析该型燃气轮机起动过程特点的基础上,重点分析了起动过程中可能产生的故障类型和原因。通过典型故障分析,提出了实际操纵运行中的注意事项和建议。
The Gas turbine starting procedure includes motor drive, air compression, ignition and burning, turbine acceleration, etc. In the starting procedure that from static condition to dynamic condition, the electric energy and the fuel chemical energy convert to the mechanical energy, and it is a sharp physieochemical change and an easily failing process. Based on analysis the gas turbine starting characteristics, the probability fault types and reasons during starting is analysed. To analyse typical fault, the precautions and recom- mendation in real manipulation and operation are given in this paper.
