FAILURE ANALYSIS FOR HIGH-PRESSURE HEATER OF 200 MW STEAM-TURBINE UNITS IN ONE THERMAL POWER PLANT[J]. Thermal power generation, 2004, (3): 44-46. DOI: 10.19666/j.rlfd.2004.03.014.
某热电厂200MW汽轮机组高压加热器故障分析及对策
摘要
通过分析某热电厂 2台 2 0 0MW汽轮机组近年来高压加热器的运行状况及其发生故障的原因
提出相应的技术改造措施
以提高高压加热器投入率
从而提高整个机组的经济性。改造后
高压加热器投入率达 99%以上
经济效益显著。
Abstract
Through analysis of operation situation on two 200 MW steamturbine units at one thermal power plant
as well as causes leading to highpressure heater failures occurred in recent years
the corresponding technical retrofitting measures have been put forward
so as to increase the inservice ratio of highpressure heaters
thereby to enhance the economic aspects of the entire unit.
