Why Is Coal Pulverized Before Combustion. Before analyzing why coal is pulverized before combustion we need to understand what is pulverization of coal. The carbon and other combustible matter in the fine coal is burned leaving the. It is predominantly adopted in large coal-fired utility boilers. The air used to spray the coal into the combustion chamber must get dry before entering the chamber.
The finer the grinding of coal the more efficient its combustion. Anthracite Bituminous Coke Pictures Formation Uses. It is predominantly adopted in large coal-fired utility boilers. The heat generated is used to produce high-pressure steam driving a steam turbine to generate electrical power. In the electricity generation process is cooled before reuse or release to the environment. In this method coal is finely ground so that 70 to 80 percent by weight passes through a 200-mesh screen.
Coal is a biological sedimentary rock that forms from plant debris.
Before analyzing why coal is pulverized before combustion we need to understand what is pulverization of coal. Coal is pulverized so as to give a greater surface to volume ratio and thus burn more readilyIndeed powdered. We refer the process of making the fuel powder as pulverization. Chemistry of coal combustion grew it was used to direct the improvements to efficiency required and later the control of pollutants produced during the combustion of coal. In this technology pulverized coal is injected to combust in a furnace in the presence of a controlled level of air. It is predominantly adopted in large coal-fired utility boilers.
