How to Optimize Coal-Fired Power Plants

According to the U.S. Energy Information Administration Although coal at U.S. power plants has cost less than natural gas for coal to be competitive its delivered cost must be at least 30% lower to make up for the differences in efficiency between a typical coal-fired plant and a typical natural gas-fired plant. These differences are even ...

Exergy Analysis of a 600 MWe Oxy-combustion Pulverized ...

In an oxy-combustion pulverized-coal-fired power plant (PC) a high CO2 content flue gas could be obtained and this allows CO2 sequestration in an efficient and energy-saving way. To better understand the thermodynamic characteristics of the oxy-combustion process a detailed exergy analysis of a 600 MWe oxy-combustion PC was carried out. The whole oxy-combustion PC system was divided into ...
