    28/1/2015 · If the average coal consumption is 340 t/h for a 500 MW and assuming the coal price to be 2,000 Rs/tons of coal, plant load factor as 0.85, this leads to a saving of 26,329,056.00 Rs/year. However, the actual magnitude of cost benefits depend on the site specific conditions like unit size, operating condition, type of fuel being fired, emission level, and frequency of soot blowing operation.

  • Conventional Coal-Fired Power Plant - an overview | …

    A conventional coal-fired power plant with post-combustion 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 problem because the flue gases from the combustion process are largely carbon dioxide.
