Mar 17, 2013· Hi ! I want to know the defination of HARDGROVE GRINDABILITY INDEX of coal and what is the effect of HGI on coal pulverisation. Please come into a discussion. We are now facing PF leak problem in our power plant as well as excessive mill wear. _____
Hardgrove Grindability Index (short HGI) is a measure for the grindability of coal. Grindability is an index, therefore it has no unit. The smaller the HGI, the harder is coal texture and less grindable is the coal. Grindability is an important factor for the design a coal mill. As grindability depends on many unknown factors, HGI is determined ...

PETCOKE. Also know as petroleum cokepetcoke is produced through the refining of petroleum and contains a high proportion of carbon.It is a form of solid carbon produced by means of heat decomposition and polymerization of heavy liquid hydrocarbons derived from the refining of crude.
Production costs associated with petcoke are minimal because it is a byproduct of the refining process, and prices are generally determined by the competitive steam coal price. Pricing is also generally discounted to compensate for sulfur, HGI and the extra difficulties of the end user managing both coal …
The Hardgrove Grindability Index Standard Reference Sample (HGI-SRS) is a sample of coal used to calibrate instruments that are designed to determine the ease with which coal can be pulverized. The HGI value provides information for determining grinding power consumption and pulverizer capacities.

We can provide high-quality Petroleum Coke and other refinery products from our reliable sources. Petroleum Coke is a by-product of the oil refining process. Refineries worldwide seek to operate more efficiently and extract more gasoline and other high-value fuels from each barrel of crude oil, a solid carbon material known as petcoke is produced.
Coke is what remains when the impurities in coal, such as coal-tar and coal-gas, are removed by high temperatures in an oxygen-free furnace. The absence of oxygen during the process prevents the coal from burning. Unlike coal, coke can be burned with little or no smoke.
Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes.Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units ...

in coal increases the HGI value, whereas the micronite and liptinite macerals decrease the grindability (Hsieh, 1976; Hower, 1987). On the basis of research of black coal from Kentucky Hower and Wild (1988) have derived that part of the HGI change can be explained by maceral composition, mainly by liptinite contents, which is the most
