Optimisation of coal fineness in pulverised

Nov 15, 2017An additional problem is a prolongation of the residence time of coal in the mill with increasing fineness, which influences the output of the mills and the boiler. The loss due to unburned combustibles (UBC) in slag and fly ash (S UBC ) depends almost entirely on the contribution of coarse fractions in the PF, while the energy consumption for

IMPROVE YOUR PULVERIZER PERFORMANCE

4. Lower air flow results in better fineness less erosion. 5. Lower air flow can result in more pyrites, but fewer burner eyebrows. 6. Lower air flow means and a greater tendency to plug with wet coal. 7. Lower air flow leaves more reserve fines in the pulverizer. 8. Also note that lower air flow leaves a deeper bed depth of coal, and thus a

Pulverized Coal Pipe Testing and Balancing

Collecting coal samples using an isokinetic probe provides the best data describing actual operating conditions inside the coal pipe. Source: Storm Technologies Inc. The isokinetic coal sampling method, although more difficult, is the best option for determining the true mill coal fineness produced and to calculate pulverizer performance.
