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.
energy demands at turndown is not significantly applicable due to the intermittent operation of the coal handling equipment. Although VFDs provide more precise control of the operating equipment, which can be considered an efficiency improvement, the reduction in overall plant heat rate is not substantial.
