12MW coal based power plant in India

Electricity is a critical input needed for the development of any country. As a country develops, the share of electricity in its primary energy mix increases. Since electricity is convenient and clean (from the perspective of local environmental impact), it is preferred as a substitute for other forms of energy. Coal based power plants in India are common for its rich and cheap coal fuel. While in coal fired power plant, boilers are necessary. For example a 12MW power plant at least needs a 75 t/h steam boiler.

75 ton circulating fluidized bed boiler in power plant

For power plants in India, our engineers recommend the coal fired CFB boilers. 75 ton CFB boiler is all right for a 12MW power station. A key advantage of CFB technology is that pollution control is built right into the combustion process. By adding low-cost limestone into the CFB, SOx is captured and removed right at the point where it is formed as the fuel burns. The CFB’s low combustion temperature (about 1,000 F less than a conventional PC peak temperature) minimizes NOx formulation. And by injecting ammonia into the CFB, NOx can be further reduced by half. CFB was promoted in the 1980s as a solution to deal with sulfur dioxide (SO2), nitrous oxides (NOx) and other pollutants produced by burning coal. But emission technology improvements in the PC plant sector, along with CFB’s relatively small plant size, limited units to sites where conditions were just right. That mainly meant the availability of difficult-to-use fuels (often called “opportunity fuels”) such as waste from bituminous coal mines (gob or boney), anthracite coal mine waste (culm) or petroleum coke (petcoke).
