Abstract: In order to study the influence of the position of extraction port of No.0 high pressure heater on the heat consumption
rate of steam turbine, this paper used EBSILON software platform to model, and used enumeration method to get the simulation
data of the heat consumption rate of steam turbine when the position of extraction port of 0 section extraction port position was
different(8-20 MPa) and the temperature of boiler feed water changed under different loads, and analyzesd them to get the change
law of the heat consumption rate of steam turbine under different load conditions, and the range of extraction port position of 0
section with reduction of heat consumption rate of steam turbine was between 8 MPa and 17.9 MPa.

 Key words: No.0 high pressure heater; 0 section extraction port position; heat consumption rate of steam turbine; boiler feed
