Analysis and Improvement on the Lower Ratio of Putting into Operation of High-pressure Heater

The lower ratio of putting into operation of high-pressure heater is an important factor which affects the safe and economical operation of turbine-generator unit in a power plant.Based on the high-pressure heater of 300MW unit in a power plant,the reason for the lower ratio of putting into operation of high-pressure heater is analyzed,the thermo-economical performance is computed with the method of equivalent enthalpy drop,a lot of good ideas are put forward,and the improvement measures are taken.So far the regular service of high-pressure heater is kept,and a good economic effectiveness is gained.
