Optimization of the Drain Mode for No. 0 High Pressure Heater

The addition of No. 0 high-pressure heater is a new technology with energy saving and emission reduction benefits, the economic analysis of No. 0 high-pressure heater under different loads and drain modes is provided on a 680 MW unit based on the Equivalent enthalpy drop method principle and the comprehensive economic drain mode for No. 0 high-pressure heater is recommended.
