| Abstract: | Turbine exhaust steam pressure(back pressure) affects thermal economy greatly in power plant practical operation.In the paper,based on the variable condition theories of steam turbine and condenser,combined EEDM equation,and used MATLAB to program,a slight increased relationship between condensing steam exhaust pressure change and thermal economy is concluded exactly and fast.It is significant for unit operation and energy-saving analysis. |
