| Abstract: | Through the calculation of dynamic numerical simulation of high-pressure feed water heater, the affection of the leakage of high-pressure feed water heater to its operation parameters such as the outlet temperature of feed water, drop pressure of pipeline of steam extraction, temperature of drainage water and drainage water level and so on are analyzed, and based on it the characteristic parameters of leakage fault of high-pressure feed water heater are extracted, which settle a foundation on establishing fault characteristic library and early diagnosing of leakage fault of high-pressure feed water heater. |
