INCREASING EFFICIENCY AND REDUCING EMISSIONS OF

2009-10-27  Improving efficiency of existing power plants, and newly build generation (approximately 140,000 MW by 2030) remains the first logical, inexpensive and necessary step. Also, efficiency of a coal-fired power plant will have a strong effect on the cost of carbon capture. With higher efficiency, the flow rate of flue gas that has to be

Increasing the Efficiency of Existing Coal-Fired Power Plants

Increasing efficiency of coal plants may help to address these concerns by reducing emissions without reducing output. Additionally, Congress may want to consider whether such efficiency improvements could be accelerated if these were implemented in a program focused on increasing the efficiency of the coal-fired power plant sector.

Efficiency improvement of coal-fired power stations

2017-3-15  Increasing the efficiency of CFPP by 1% reduces CO 2 emissions by between 2 and 3%. In addition to CO 2 abatement, and probably more important for economic expansion, comes the reduction in use of coal/kWh and hence reduction in running costs, plus overall reduction in the use of coal and extension of the lifetime of coal
