Abstract A numerical model has been developed for the dispersal of aerosols downwind from a coal-fired power plant The main goals were to evaluate with a mathematical simulation the evolution of the spatial extent and particle size distribution of the aerosol material and to predict settling rates affecting the surface environment in the downwind path

The direct cost of coal grinding is a function of the wear and tear of the powdered coal mill which in turn is influenced by the expected particle size spectrum of the coal dust and thus of the

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
