the pulverized coal firing system leads to incomplete combustion, thereby leading to higher specific thermal energy consumption and burning loss. The modified pulverized coal system provides a solution towards eradicating unburnt coal particles, there by leading to lower specific fuel consumption. Salient features, Investment Benefits
This practice of pulverized coal firing system is based on outdated concept and this has following limitations. Poor furnace design. Use of cold air for combustion (recuperator gets choked and removed). Size of pulverized coal is very coarse (90% above 200 mesh). Poor combustion efficiency. Simple pipe is used as a burner.
Coal is the favorite fuel for the electricity generation in countries like India and China. Abundant supply of coal locally and sustained high prices for imported natural gas and oil make coalfired generation of electricity more attractive economically. is approximately .
On average, the Indian power plants using India's coal supply consume about kg of coal to generate a kWh, whereas United States thermal power plants consume about kg of coal per kWh. This is because of the difference in the quality of the coal, as measured by the Gross Calorific Value (GCV).
Dec 30, 2018· There are mainly two methods of firing steam boiler with coal as fuel. One is solid fuel firing other is pulverized fuel firing. Let us discuss one by one. There are mainly two types of solid fuel firing system. Hand Firing; Mechanical Stroke Firing; Smaller size boiler can be operated by hand firing system. This system was commonly used to drive coal engine locomotive in past.
Coal clinkers form when noncombustible elements contained in coal such as iron, calcium, silicon, aluminum and sodium interact with sulfur and carbon at high temperatures. These elements melt together with clays and alkalis to form a glassy slag that eventually hardens into clinkers.

Coal fired power plant. Their use provides around 40% of the world's electricity and they are primarily used in developing countries. Countries such as South Africa use coal for 94% of their electricity and China and India use coal for 7075% of their electricity needs, however the amount of coal China uses dwarfs most other countries (see the data visualization below ).
