In a coalfired steam station—much like a nuclear station—water is turned into steam, which in turn drives turbine generators to produce electricity. 1. Heat is created. Before the coal is burned, it is pulverized to the fineness of talcum powder. It is then mixed with hot air and blown into the firebox of the boiler.

Abstract The share of coal generation in the global electricity production remains stable and prevails over other primary energy sources. A decrease in the coalfired power generation in some EU countries and the United States is balanced by its stable growth in Asia (China, India, Indonesia, South Korea) and Africa (South Africa). In 2021, global coal generation increased by 9% to a new all ...

2. Description of the coal firing process. Coal firing is one of the main processes in a thermal power plant and it consists of several stages. The coal is transported from a bunker through dosers and feeders to recirculation channels and ultimately to mills. Partially dried coal that reaches the mills is additionally dried and then ground.

Paul Breeze, in CoalFired Generation, 2015. Coal combustion is a dirty process, releasing a range of pollutants including sulphur dioxide, nitrogen oxides, carbon dioxide, volatile organic compounds, ash and a range of heavy metals. If these are not controlled they can enter the atmosphere, causing damage to the environment and to human health.

Most traditional power plants make energy by burning fuel to release heat. Thus, they are called thermal (heatbased) power plants. They burn fuel with oxygen to release heat energy, which boils water and drives a steam turbine. This is majorly the one used by coal and oil plants. Natural gas uses a different process.

Coalpowered thermal plants are the primary source of energy production around the globe. More than half (%) of the Indian power plants use coal for power production. Coal burning in power plants results in coal combustion residuals, which contain coal fly ash (CFA) that is recognized as principle byproduct. CFA is difficult to characterize due to its broad compositional variation. Hence ...
