Pulverization of coal is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.
The work of the coal power plant begins with the arrival of coal from the coal mines via trains. This coal is then transported to the power plant to be converted into a powder form. The main reason behind converting it into powders is to increase the efficiency of burning by increasing its contact area exposed to fire in the burner as compared ...

Coal electrical generation (black line), compared to other sources, Coal power generation in 2011 by state.. Coal generated about % of the electricity at utilityscale facilities in the United States in 2022, down from % in 2014 and 51% in 2001.
Brown and black coal are mostly used as a source of fuel for power stations. Burning the coal produces heat which is used to make steam, so the the coal is sometimes called thermal or steam coal. The steam spins turbines to generate electricity. In Australia in 2017 coal was used to produce about 60% of the nation's electricity requirements.

Nearly 130,000 homes in the still burn coal for heat. Despite decades of decline and concerns about climate change, companies in the coal homeheating business are optimistic about the future.
Pulverized Coal Fired Steam Boilers is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. The basic idea of a firing system using pulverized fuel is to use the whole volume of the furnace for the combustion of solid fuels.
The electric power sector has accounted for the majority of coal consumption since 1961. coal consumption by consuming sector and by amount—in million short tons (MMst) —and percentage share of total coal consumption in 2022 was: 1. Electric power— MMst—%; Industrial total— MMst—%
Coal dust is a fine powdered form of coal which is created by the crushing, grinding, or pulverization of coal rock. Because of the brittle nature of coal, coal dust can be created by mining, transporting, or mechanically handling it.
