Exergy Analysis and Efficiency Improvement of a Coal

2013-4-16 · 2. Process description of a coal-fired power plant A coal-fired power plant burns coal to produce electricity. In a typical coal-fired plant, there are pulverisers to mill the coal to a fine powder for burning in a combustion chamber of the boiler. The heat produced from the burning of the coal generates steam at high temperature and pressure.

Coal-Fired Power Plants: Additional Hazards Require

Coal Dust Hazards. For a fire to occur, the fire triangle needs to be present - oxygen, fuel, and heat. An explosion happens when two other elements are added to the equation - dispersion of dust and confinement of dust, as shown in diagram A. Oxygen and fuel cannot be avoided in a PRB coal-fired power plant, but the heat source can originate from several different sources.

Pulverized coal-fired boiler - Wikipedia

2019-9-27 · A pulverized coal-fired boiler 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 pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
