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...

Pulverization of coal is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.
In this study, basic co-firing characteristics of pulverized coal and ammonia were investigated using a bench-scale single burner test furnace. A schematic diagram of the single burner test furnace is shown in Fig. 1. The rated thermal input of the furnace is 760 kW, which corresponds to approximately 100 kg/h of coal for common bituminous coals.
Power generation in South Africa has historically and continues to depend on the use of pulverized coal combustion. The pulverized coal boilers are used by the majority of power stations around South Africa. Although other types of technologies, such as circulating fluidized bed (CFB) are available which are not used for this purpose in South Africa. CFB technology is versatile …

South Africa is the third largest coal producer in the world, and coal accounts for 64 % of South Africa's primary energy supply [2]. Electricity generation accounts for 61 % of the total coal consumption in South Africa and more than 90 % of the country's electricity requirements are provided for by coal-fired power plants [2].

A coal burner is composed of a pulverized coal machine, combustion machines like a combustion chamber and air supply system, and a control system. The coal is pulverized and mixed with air before being ignited. Coal burners are used to provide heat for boilers, furnaces, and kilns in industrial production and daily life.
Given South Africa's abundant coal resources, large quantities of CCPs are produced both in the generation of electricity (ESKOM) and the production of liquid fuel ().

Within the sub systems of a coal-fired power station, the task of a boiler is to produce the correct mass flow rate and temperature of steam which is passed to the steam turbines for the generation of electricity. For a drum-type boiler, steam generation starts with the combustion of pulverised coal and air in the furnace of the boiler arrangement.
