coalfired

Coalfired refers to a method of obtaining energy or heat by burning coal, most commonly in a furnace or boiler. The process of coalfired power generation involves the combustion of coal to produce steam, which then drives a turbine to generate electricity. Coal-fired power plants are one of the largest sources of electricity worldwide and have been in operation since the early 20th century.

The coalfired process generally begins with the preparation of coal, which is crushed into smaller pieces to increase its surface area. This is followed by ignition of the coal in a furnace or boiler, typically using a flame preventative system to ensure safe burning conditions. The heat generated by the combustion of coal is then used to boil water and produce steam.

As the steam expands, it drives a turbine connected to a generator, which converts the mechanical energy of the turbine into electrical energy. The steam is then condensed back to water and recirculated through the boiler to be reheated and expanded again. This process is known as the Rankine cycle and is the fundamental operating principle of coalfired power plants.

Coal-fired power generation is a significant source of greenhouse gas emissions due to the combustion of coal, which releases carbon dioxide (CO2), sulfur dioxide (SO2), and nitrogen oxides (NOx) into the atmosphere. As a result, many countries are adopting cleaner energy sources or implementing pollution-control measures to reduce the environmental impact of coalfired power generation.
