M701F4型燃气轮机联合循环机组调试中的主要问题及解决方法

摘要

介绍了三菱M701F4改进型单轴燃气轮机联合循环机组在调试中遇到的主要问题，如透平冷却空气系统减温水流量低保护跳机、临时滤网堵塞、燃气管道泄漏等。针对发生的问题，在原因剖析的基础上，提出解决措施和预防建议，对同类型机组具有一定的借鉴意义。%This paper introduces the main problems in test of the improved Mitsubishi M701F4 single shaft gas turbine combined cycle units, such as turbine shutdown protection due to low cooling water flow of cool-ing air system, temporary filter clogging, gas pipeline leakage, etc. To solve the problems, this paper brings forward solutions and prevention advices on the basis of cause analysis, which can be used as reference for units of the same type.
