【正文】 ion pressure steam turbine unit of allowable maximum output. Plant high add in actual operation of the main problems existing in the below. water supply auto bypass device sealing design not beautiful Import represent valves casing bypass sleeve clearance place leakage. Found in operation, 15 high temperature with its exports than the original export ℃ temperature low around 6. After the overhaul into water temperature obviously increase, shortly after, but running back to the original relatively low value. Overhaul its seal, found by plugging material was washed run, and certainly some pits scouring by water into inner seriously. So according to the original design of the seal clearance will lose its practical significance, and now will manufacturers in the overhaul of the original ~ mm to mm, and gap with highpressure airproof material change, the effect is good.High add entrances water room clapboard leakage. A power plant in operation of water supply temperature unit obviously low (℃ for 240 ℃) design value. Found in VSD repair gateway water board is very big, and impact, gap between inner cavity with clapboard leave, make water to shortcircuit, after the flood water temperature, obviously rises, can reach 230 ℃. scanty water system automatically puttinginservice proactively adverse We plant of the 8th high add, hydrophobic automatic can39。 TouRuLv。In the operation of high pressure heater problems and countermeasuresabstract: coalfired power plants in highpressure heater due to work under high temperature and high pressure, so easily damaged, damage could not invest in operation with high water temperature will drop, power, this paper points out the existing high pressure heater leakage pipes and bilge mouth water distribution automatic bypass seal not beautiful, scanty water system automatically into bad and so on some mon problems, analyses the causes of these problems, and puts forward corresponding countermeasures. Keywords: high pressure heater。 Leak。 countermeasures1. preface Steam turbine thermal heating system is adopted to improve the unit operation of the important means of economic. Back to heat heating system operation reliability and performance directly affected the height, plete unit operation of economy TouRuLv is economic indicators heater in important evaluation indexes. As coalfired power plants to the large capacity, high parameter unit development, high press
