The modern use of pulverized fuel in power stations

As a result of the experimental work carried out in the Birmingham electric power station, it has been demonstrated that the use of pulverized fuel gives a higher combustion heat efficiency in the boilers than is obtained with mechanical stokers. Boilers having a capacity far greater than those equipped in the past with mechanical stokers can be used, with a consequent reduction in the capital cost of boilers and boiler house; this is a set-off against the higher capital cost of the pulverized-fuel equipment compared with mechanical stokers. The evolution of pulverized-fuel installations is tending towards reduced equipment and greater simplicity in operation; this is effected by eliminating the coal driers and the conveying and storage of the pulverized fuel.
