process of decommissioning a coalfired power plant is not always clear and may overlap with remediation and redevelopment. Once the owner decides to close the plant, the owner should develop . a strategy for managing the decommissioning process that serves his or her business needs. A wide range of management strategies may be
It offers a radically different approach to the problem. A conventional coalfired power plant with postcombustion capture has to separate carbon dioxide from a flue gas mixture in which there is a large amount of nitrogen. The oxyfuel process, by removing the nitrogen at the start, so that coal burns in oxygen instead of air, sidesteps this ...

How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over. Here's a real ...
