摘要
高压给水加热器是汽轮机发电机组回热系统中的重要设备,运行高压给水加热器可以提高锅炉给水温度,降低机组热耗。其能否安全运行对整个回热系统有着重要的影响,而正常疏水管道振动是高压给水加热器常见的问题之一。本文主要对高压加热器正常疏水管道振动的原因进行了分析,并提出了详细的应对策略,对高压加热器的设计、制造及电厂运行具有借鉴意义。
High pressure feedwater heater is the key auxiliary equipment in an extraction steam sys- tem of steam turbine generation unit, which can raise the temperature of feedwater and reduce the energy loss. The safety of high pressure feedwater heater has a great influence on the whole extrac- tion steam system. Normal drain p：ipe vibration is one of the common problems of high pressure feed- water heater. The causes of normal drain pipe vibration have been analyzed and detailed counter- measrues have been put forward in this article, which is useful to the design, fabrication and opera- tion of HP heaters.
