Raw coke. Coke is a grey, hard, and porous coalbased fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the ...

Coal mill dust collectors have a substantial effect on productivity, yet have received relatively little attention as companies implement costsaving programs, like the use of petcoke as a fuel reduction measure. Petcoke is typically ground finer than coal, and it has a particularly sticky nature that makes it more difficult to clean from ...

Coal, lignite or petcoke are ground in the Pfeiffer vertical mill by using available hot process gases. The grinding plant can be inerted. The raw coal is dried while being ground in the mill even if feed moisture exceeds 25%. The feed size that can be handled is up to 100 mm, making twostep precrushing unnecessary.

Coke Data. Coalderived coke was the fuel used in most static kilns and so was the dominant fuel in the cement industry in the nineteenth century. Coal could not be used in static kilns in which the fuel is fed in with the raw material, mainly because, during the gradual heatup of the charge, the fuel's volatiles are lost without ignition, so ...

But existing coal mill was capable of giving 5% max on 90 micron (design was 15% on 90 micron for Indian coal which is softer). Pet coke is very hard to grind (Hard grove Index 3545) against 6065 HGI (Hardgrove Index) in normal coal. Therefore without any modification, it was not possible to get targeted value of fineness in pet coke.

Industry is concerned about the pending inventories of pet coke (which may vary from 15 days to one month or may be higher on case to case basis.) Another concern is of storage facility. Considering that calorific value of coal is much lower than pet coke, the quantity of coal required as a fuel to replace pet coke will be much higher.

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.

Petroleum Coke. Petroleum coke is a carbonaceous product obtained in the oil refining process. It is abbreviated as Coke or Petcoke, and is a carbonrich solid material derived from final cracking process — a thermobased chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains— that takes place in coker units.
