Optimising fuel flow in pulverised coal-fired boilers

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

Coal-Fired Boiler - an overview | ScienceDirect Topics

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).
