For a 660 MW coalfired power plant, they reconciled operating data to reduce measurement errors for a heat balance analysis, but only around the deaerator and highpressure feedwater heaters (FWHs) [15]. A brief review of previous studies on data reconciliation in the power industry, including fossil energy applications, can be found in [15].

The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a predetermined size in order to increase the surface area of the coal. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.
