Optimising fuel flow in pulverised coal

Jan 25 2016 0183 32 Poor pulverised fuel PF distribution to the burners in a coal-fired boiler reduces combustion efficiency increases wear of equipment and emissions and so is bad for the economics of a plant In her new report for the IEA Clean Coal Centre Optimising fuel flow in pulverised coal and biomass-fired boilers Dr Maggie Wiatros-Motyka explains that...

PULVERIZED COAL FURNACES

Pulverized coal pulverized fuel-pf has been fired in rotary cement kilns see Kilns and boiler furnaces see Boilers The latter are basically boxes lined with tubes in which water is evaporated and contain a water/steam mixture The coal is pulverized to a fine powder usually so that 70 is less than about 75 μm in size before being carried by part of the combustion air stream to the...

Pulverized Coal

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...
