Improvement of power plant efficiency due to higher steam condition is frequently foreseen to outbalance the carbon capture penalty. This work focuses on the conceptual design of two coal-fired power plants using CO 2 as working fluid: one with post- combustion MEA-based CO 2 capture and one with oxy-combustion CO 2 capture with …

1.. IntroductionThe use of coal for electricity generation is increasing rapidly since coal is a relatively inexpensive energy source. Its energy price is estimated to be about US$ 1.89/MMBtu (million British thermal units) whereas natural gas and oil are US$ 11/MMBtu and US$ 21/MMBtu (EIA, 2008a, Pew Center, 2008), respectively.This leads …

Producing electricity in coal power plants can take place in a number of ways with varying degrees of efficiency. In conventional coal-fired plants coal is first pulverised into a fine powder and then combusted at temperatures of between 1300 and 1700 o C. This process heats water in tubes in the boiler so that it becomes steam at a pressure of around 180 …
