The calculation and analysis on influence of steam extraction pressure lose on thermo-economy of coal-fired units
It is ripe in technology and doable in practice that one old condensing turbine with proper parameter is remade to be postposition turbine of the back extraction pressure turbine.
The energy-saving results of these units can be further improved by widening the regulating range of the extraction pressure and by using tow-stage heating of district-heating return water.
