CAO Zhi-yang(Huaneng Pinliang Power Generation Co Ltd. CAUSE ANALYSIS OF HIGH-PRESSURE HEATER LEAKAGE FOR 300MW UNIT AND COUNTERMEASURES THEREOF[J]. Thermal power generation, 2007, (1): 54-57. DOI: 10.19666/j.rlfd.2007.01.016.
The operational performance and reliability of high-pressure heater directly affects the economic behavior and safety of unit.The leakage troubles have occurred many times on high-pressure heater no.3 of unit no.2 in Pinliang Power Plant
the tube-bundles being freguently replaced. Through analysis of the drain-regulating valve and the water-level in operation
the causes resulting in leakages of the high-pressure heater have been found out
and measures adopted for preventing tube-bundle leakage being presented.
