چکیده انگلیسی
Three generally considered CCS technologies were modelled - oxyfuel combustion and ammonia scrubbing based post-combustion (subcritical power plant with fuel drying) and pre-combustion (IGCC with Rectisol method for CO2 separation), for which the WHR options have been analyzed. Systems with WHR improve plant efficiency, but also flexibility due to decoupling waste heat streams from the main steam cycle. Results are presented for scenarios of 250 MWe coal fired power plants, applied to central European conditions. The efficiency increase in the case of an IGCC-CCS plant is up to 4.2 percentage points, followed by oxyfuel with 1.3 percentage points while effectiveness in post-combustion is minimal, 0.1Â percentage points. The economic effect is positive in all CCS plants, allowing for improvements in the LCOE by up to 6.3%.
