The Impact of Using the Post-Combustion CCS on the Coal-Fired TPP Internal Consumptions

CO2 Capture and Storage (CCS) is a way to limit the impact of the power plants on the environment. Using the numerical modeling, the paper analyzes the impact of the post-combustion CCS on the coal-fired Thermal Power Plants (TPP) internal consumptions. The steam turbine power is decreased by the steam flow rate requested by the CO2 capture process. The power consumed by the cooling pumps decreases. The CO2 compressor unit requests about 9.4 % from the power at the generator clamps (Pgc). The Pgc decreases with 15.3 % and the net power decreases with 24.4 % if the CCS is used. The net efficiency of the TPP is reduced by 9.8 percentage points if the CCS is used. The paper compares the internal consumptions of the TPP with and without CCS.
