某燃机热电减温水喷嘴频繁堵塞原因分析及防治措施

某燃气轮机电站运行中制冷站减温水喷嘴频繁堵塞,喷嘴需经常人工清理,管道输送泵压力、频率和开度增大,电耗增加,严重影响制冷机系统正常运行状态。通过现场系统查定、减温水水质分析、堵塞物能谱分析等技术手段,分析发生异常现象的原因并得出初步结论,并针对性提出合理有效的防治措施。

Causes Analysis of Frequent Blocking at Desuperheating Water Nozzle and Prevention Measures in a Gas Cogeneration Power Plant

The desuperheating water nozzle of refrigeration station was frequently blocked during operation. The nozzle was needed cleaning manually. The pressure&frequency of the pipeline transmitting pump was forced to open largely, and the power consumption also increased, which seriously affected the normal operation state of the refrigerating machine system. In allusion to above problems, we took a series of technical means including on-site system verification, water quality analysis, energy spectrum analysis of blocking matter, then we drew a preliminary conclusion and put forward correspondingly reasonable and effective prevention measures.
