Fossil fuel power plants generate significant amounts of CO 2 emissions into the atmosphere, which are believed to be the main cause of climate change. Among CO 2 mitigation options, carbon capture and storage is considered the only technology that can significantly reduce the emissions of CO 2 from fossil fuel combustion sources. There are mainly three technological routes for CO 2 capture ...

Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.

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.

Coalfired power plants are the largest source of anthropogenic carbon dioxide (CO2) emissions into the atmosphere, with more than billion tonnes of CO2 emitted annually. In order to mitigate the emissions of CO2 from coalfired plants, several measures were proposed, such as increasing the efficiency of the plants, cofiring biomass with coal, and capturing and storing CO2 deep underground.

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.
