Abstract To make coal more attractive for industrial users, the National Coal Board is collaborating with boiler manufacturers to improve conventional firing equipment and ancillaries and to develop new concepts, particularly fluidised bed combustion. Most stoker types are now available with automatic electrical ignition, load following and ash removal. The NCB has operated three fluidised bed packaged boilers at industrial sites since 1977/78 and the expertise and data gained have been applied in collaboration with manufacturers to design a range of fbc fire tube and water tube boilers, with outputs from 1 MW to 30 MW. Several commercial units, incorporating automatic start-up and load following are now in operation. Fbc units to produce hot combustion gases or clean heated air for drying kilns are also commercially available. An 85 MW pressurised fbc facility is being operated on behalf of the International Energy Agency. The NCB has encouraged the introduction of pneumatic coal conveying for handling coal on industrial sites. Two types are available, dense phase for any coal grade, including high content of wet fines, and dilute phase, a lower cost system for coals without fines. The use of pneumatic conveying of coal, and also of ash, together with coal and ash storage in closed bunkers or silos, ensures that coal firing offers a degree of cleanliness and reliability previously associated only with oil or gas firing.
