Abstract

This paper describes the performance of electrostatic meters for measuring and controlling pulverised fuel on coal-fired power plant. Typical data obtained from on-line measurements of pulverised fuel (PF) flow in a large-scale power plant demonstrate how the system can be used to measure the fuel velocity and distribution (split) to indicate the conveying conditions in each individual conveyor. Results from laboratory tests carried out on a bifurcating system show that the split between two conveyors can be balanced by controlling the back pressure with PF meters providing on-line feedback of mass flow measurements. Based on the results, some of the immediate benefits of continuous PF metering are discussed showing the potential to increase plant efficiency by optimising the fuel distribution to the burners.
