Abstract:
The analysis of a 600 MW supercritical power plant with parameters of life steam at 30 MPa/
/650o C and of reheated steam 6 MPa/670o C was made. Power plant is equipped with the
following units: oxy type pulverized fuel boiler, ‘four-end’ high temperature membrane air
separator and carbon dioxide capture system which were modeled. With the assumption of a
constant gross power of the analyzed power plant, the thermal efficiency of the boiler and the
steam cycle efficiency were calculated. These parameters were designated as a function of the
recovery rate of oxygen in the air separation unit. This allowed to determine gross and net
efficiency of electricity generation.
