Pulverizer Fire and Explosions

The presence of combustible materials in the pulverizer is usually the largest contributor to pulverizer fires. In most cases, pulverizer fires begin in the under bowl area of the pulverizer that is a very hot environment with an abundance of air. Accumulations of debris or coal anywhere in the pulverizer will increase the chance of a mill fire.Pulverized coal-fired boiler - Wikipedia,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.Fire and Explosion Prevention in Coal Pulverizing Systems,tration of coal in air below which an explosion does not occur), but do not have an upper explosive limit as long as the coal/ air mixture can be considered a cloud. In practice, a fire occurring during normal pulverizer operation does not result in an explosion. The rich coal…
