  • Optimising Fuel Flow In Pulverised Coalfired Boilers

    Optimising Fuel Flow In Pulverised Coalfired Boilers

    Jan 25, 2016 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...

    PF boilers deliver often the most competitive biomass based electricity with respect to power generation efficiency, capital investment cost and generations costs [1]. A key issue when the pulverized fuel boiler technology uses biomass as fuel instead of the traditionally use of coal is the large change in ash composition and ash properties.

    Pulverized fuel (pf) combustion in a boiler for power generation is by far the most common approach for the utilization of low rank coals. The properties of low rank coals (in particular, moisture and alkali content) mean that such an approach is often very inefficient, leading to very high CO 2 emissions. Low rank coals, however, are inexpensive, and in some regions represent a significant energy resource.
