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 ...

Most traditional power plants make energy by burning fuel to release heat. Thus, they are called thermal (heatbased) power plants. They burn fuel with oxygen to release heat energy, which boils water and drives a steam turbine. This is majorly the one used by coal and oil plants. Natural gas uses a different process.

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.

Stage 1 The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2 The second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam.
