Pulverisers are one of the major auxiliaries in a coal fired thermal power station. They are used for grinding the precrushed raw coal, so that the pulverised product at desired PF fineness can be fed directly to the furnace of the steam generator.

50 g of air dried coal featuring a grain size in the range between and mm are filled into the sample mill and a weight is put on the mill's grinding stone. After 60 rounds the grinded coal is put on a sampling sieve. Factor D equals the fraction of the coal passing through the sieve of 74 μm corresponding to 200 mesh.

Petroleum coke has been used as a substitute for portions of the coal feed; although the use varies with the price of the coke. Petroleum coke has high concentrations of Ni and V, with up to 9463 ppm Ni and 1425 ppm V in the fourthrow ESP fly ash, and 26,440 ppm Ni and 3340 V in the 100 × 200mesh portion of the latter ash, at a western ...

In the process, a significant portion of the feed (~15% of volume) is converted into elemental carbon called petroleum coke. Refiners separate the coke from the other coker products and sell it as a product. The primary end use for pet coke is as a solid fuel, used as a substitute for coal in furnaces and boilers.

High grade petcoke which is low in sulphur and heavy metals can be used to make electrodes for the steel and aluminum industry. But the majority of petcoke manufactured globally, approximately 7580%, is of a much lower grade, containing higher levels of sulphur and heavy metals and is used solely as fuel. The majority of petcoke produced in ...

The analysis of individual mill design operation is complex; so, for simplicity we will consider a typical mill layout for one mill type only. As VSMs have come to represent the bulk of the power station mill fleet, the explanation of mill operations will be based on this mill type. Fig. illustrates the typical key components of a VSM.
