Abstract

In the paper results of analysis for 900 MW supercritical coal-fired power plant integrated with absorption CO2 separation installation and gas turbine unit are presented. In this unit the gas turbine with evaporator is the heat source for desorption process, which is realized in CO2 separation installation. The aim of the analysis was to determine the thermodynamic, ecological and economic evaluation indicators, which are defined in the paper. Analysis were carried out for variable heat demand required for desorption process. Additionally, the influence of change of emission allowances price on chosen economic evaluation indicator was analyzed.
