Coal Boiler Types Environmental

Coal-fired power station - Wikipedia

As a type of thermal power station, a coal-fired power station converts chemical energy stored in coal successively into thermal energy, mechanical energy and, finally, electrical energy.The coal is usually pulverized and then burned in a pulverized coal-fired boiler.The heat from the burning pulverised coal converts boiler water to steam, which is then used to spin turbines that turn generators.

Using Wood and Coal for Home Heating - Environmental

Using coal and other mineral solid fuels for home heating will usually result in higher emissions of both local air pollutants (such as particles and sulphur dioxide) and carbon dioxide (the greenhouse gas) than an equivalent natural gas fired system, and therefore coal fired heating will normally have a higher environmental impact than gas.
