摘要:

介绍了低低温烟气换热器(LGGH)系统在火电厂的运用情况,为解决其目前存在的泄漏、腐蚀、堵塞等缺陷,在运行中需加强运行参数的监视、分析与调整。在机组检修时,需对降温器入口导流板进行优化,对换热器进行清理、检查、冲洗、查漏及测量评估,以提高低低温烟气换热装置的运行安全、可靠性。

Abstract:

It introduces the application of lowtemperature gasgas heater (LGGH) in thermal power plants. In order to solve the existing defects such as leakage, corrosion and blockage, it is necessary to improve the monitoring, analysis and adjustment during operation. During overhaul period, it is necessary to optimize the flow guide plate at the entrance of the cooler, to clean, check, flush, troubleshoot , measure and evaluate the heat exchanger, so as to improve the safety and reliability of the lowtemperature gasgas heater.
