Jul 01, 2014· This study presents a methodology to estimate the instantaneous pulverised coal flow rate of the E-type vertical spindle coal mills. Modifications over a six-segment coal mill model have been proposed, and particle swarm optimisation technique with Kalman correction has been used to optimise the unknown parameters of the modified model by using real plant data.
