| Abstract: | 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. |
