The wear of mills may reduce the possibility of controlling the PF particle size and lead in extreme cases to mechanical damage of the mill elements. Erosive wear of ducts and burner components may cause combustion problems. In terms of operation, erosivity is one of the coal crucial characteristics [16].

20. Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% ...

It can be said that coal as a solid fuel is far more benign as biomass. As a consequence, power stations have started to use modern online measurement and control systems to measure the two phase flow inside PF (pulverised fuel) piping to bring light to the darkness of these problems. There are three main areas to be looked at: The burners ...
