摘要:现阶段,燃气轮机广泛应用在工业、船舶以及电力等机组系统中,并发挥着良好的应用效果。但是对于燃气轮机的起动过程来说,常常会受到各类因素影响,导致燃气轮机在起动环节出现各种故障,如果不能及时的排查和处理燃气轮机故障,就会影响整个机组运行,从而引发更大的故障,不利于企业的发展。为此,文章基于燃气轮机起动过程中常见的故障类型进行分析,并针对这些故障提出有效的排除对策,保障燃气轮机的平稳运行。
Abstract: At this stage, gas turbines are widely used in industrial, shipbuilding, and electric power generation systems, and they are exerting good application effects. However, for the starting process of a gas turbine, it is often affected by various factors, resulting in various failures of the gas turbine during the starting process. If the failure of the gas turbine cannot be checked and dealt with in time, it will affect the operation of the entire unit and cause greater failures. , Is not conducive to the development of enterprises. For this reason, the article analyzes the common fault types during the starting process of the gas turbine, and proposes effective troubleshooting countermeasures for these faults to ensure the smooth operation of the gas turbine.

受到经济全面发展的影响,人们对能源系统引发的环境问题也越来越重视。随着燃气轮机的不断推广与应用,有效降低了企业投资成本,提高灵活度,同时凭借高效的运行和环保特点,得到了广泛推广与运用。燃气轮机起动系统主要包括启动马达、燃油系统、控制器、点火系统等几个部分。当燃气轮机起动开关开启时,首先由启动系统根据控制指令进行逐步提高系统压力,当液压的压力升高到一定值后,马达运转,通过棘轮离合系统带动汽轮机开始运行,当汽轮机转数达到供油转数后,控制系统接收燃油系统传输的指令,并根据指令进行共有操作,当高压压气机的转数符合点火转数时,点火系统便开始工作,然后燃气轮机转数逐渐平稳,从而燃气轮机顺利起动。但是在燃气轮机的长时间运行中,难免会出现各类故障问题,而起动故障属于燃气轮机的典型故障,只有做好燃气轮机起动过程中的故障分析与排查,才能保障燃气轮机的可靠运行,促进企业的健康发展。……
