| Abstract: | Through statistics, the failures frequently occurred in heater system, especially in the high -pressure heater system, to be secondery only after tube - burst of the boiler, taking the second place of troubles in the power plant. Among statistics of various heater troubles, leakage of tubulature occupies the max. proportion. Taking units in Xuzhou Power Plant as example, various leakage phenomena of high-pressure heaters have been presented, and causes leading to said leakages being analysed. In order to ensure decreasing the leakage accidents and protecting safety of the unit, preventive measures for ensuring safe operation of high - pressure heaters have been put forward. |
