the coal/ air mixture velocity has slowed and is equal to the flame speed. From this we see the importance of maintaining burner operating velocities above the minimum specified by the manufacturer. In practice, the more dangerous condition is an ignition source,, a fire, within the coal pulverizing or conveying equipment.
Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

dries coal in the grinding zone and carries pulverized coal particles upward into a classifier. Fine pulverized coal exits the outlet section through multiple discharge coal pipes leading to the burners, while oversized coal particles are rejected and returned to the grinding zone for further grinding.
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.
Feb 09, 2018· Pulverized coal is the most widely used fuel in the steel sector. Watch how its selection, pulverization and quality check using a bomb calorimeter is key to an energy efficient system.
A pulverized coalfired 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.
burners that we have developed by using CFT to reduce the slagging caused by subbituminous coal and other types of coal, and also the ultra low A/C (Air/Coal ratio, the weight flow ratio of primary air to pulverized coal) burners designed for the combustion of dried lignite coal. We have already reported on our burners for single firing of semi
