There is an empirical relationship between HGI value and the rank of the tested Coal; higher the rank of the coal, higher is the HGI value. HGI value is also influenced by the petrographic nature (types of macerals present) of the coal. HGI of bright coals, containing 8990% Carbon, can reach a maximum value of 105. But for anthracite, the HGI value has a low value of 35.

represented by coal. As the body of scientific knowledge on the physics and chemistry of coal combustion grew, it was used to direct the improvements to efficiency required and, later, the control of pollutants produced during the combustion of coal. This involves not only the control of emissions of particulates, SOx and oxides of nitrogen but also of trace elements, polycyclic aromatic ...

The average calorific value of product gas for types 1 and 2 is MJ/m 3 and MJ/m 3 respectively, while an increase of injection flow rate produces an improvement of the calorific value for both types of coal. Additionally, it is suggested that the reacted carbon and the product gas volume can be estimated with the volume of oxygen injected regardless of the coal quality if the ...

 · Coal Word Scramble Activity. In this activity, you will check your knowledge regarding the facts, current uses, and future of coal presented in the lesson.

Many coal blending theories have been proposed for producing coke of a specific targeted quality by blending various kinds of coals. For example, Jo (1965) considered that coal consists of two components, a fibrous component and a caking component, and that increasing the strength of fibrous component (coal rank) and the addition of a suitable amount of caking component (caking property) .

 · Coal washing The raw coal extracted out from the coal mine is processed through different techniques to achieve the desired qualities. These result in higher economic value of run ofmine (ROM) coal.

 · The coal is also egorized into different types as per their CVs (Calorific Value).There are mainly 4 types of coal and below mentioned are the coal types as per their CVs (Calorific Value)in an ascending order: Peat. Lignite. Bituminous. Anthracite. In most of the thermal power plants we use Bituminous coal, because it is having a good calorific value and it is present in a larger amount in ...

RPMGlobal's Underground Coal Solution (UGCS) allows engineers to focus on applying their skills to run more scenarios and deepen their analysis of multiple scenarios. Planners now have the right tools that help them to identify options that deliver greater value that would have otherwise been overlooked.

Bituminous coal appears shiny and smooth when you first see it, but look closer and you may see it has layers. Subbituminous: Subbituminous coal is black in color and dull (not shiny), and has a higher heating value than lignite. Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon.
