Gray Coal Fried Steam Boiler

A coal-fired steam boiler is a type of boiler that uses coal as its fuel to generate steam. It is one of the oldest and most common methods of producing steam power. Coal is burned in the boiler's combustion chamber, and the heat energy released during the combustion process is used to convert water into steam.

Fuel Supply: Coal is stored in a coal bunker and fed into the boiler through a conveyor system. The amount of coal fed into the boiler is controlled based on the steam demand.

Combustion: The coal is ignited in the boiler's combustion chamber, where it combines with oxygen from the air to produce heat. The combustion process releases various combustion gases, including carbon dioxide, sulfur dioxide, and nitrogen oxides.

Heat Transfer: The heat generated from the combustion process is transferred to the water circulating in the boiler's tubes. The boiler has a network of tubes through which water flows, absorbing heat and converting it into steam.
