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 fireboxAdvanced Pulverized Coal Injection Technology and Blast ,In order to reduce the cost of running blast furnaces (BFs), injected pulverized coal is used rather than coke to fire BFs As a result of this, unburned fine materials are blown with the gas into the bosh and dead man areas with possible detrimental effects on gas flow and permeability of the coke columnNumerical Simulations of Pulverized Coal Combustion,1 Numerical Simulations of Pulverized Coal Combustion Ryoichi Kurose* Department of Mechanical Engineering and Science, and Advanced Research Institute of Fluid
