Coal gasification is the process of producing syngas–a mixture consisting primarily of carbon monoxide, hydrogen, carbon dioxide, natural gas, and water vapour (H2O)–from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas". Coal gas is combustible and was used for municipal lighting, and heating, before the advent of large scale production of .

Mining Hardgrove Grindability Index (HGI) The Hardgrove Grindability Index (HGI) is a measure of coal's resistance to crushing. Grinding studies, and the resulting HGI, allow many different types of coal users to evaluate how coals will perform in their mills, allowing them to estimate grinding power requirements and throughput capacities. SGS...

Oct 21, 2011 · In the case of coal-grinding or storage (as one might find in a cement plant) it is not possible to remove the fuel (coal) or ignition source (grinding energy, heat, static charges) and so one has to concentrate on removing the third necessary component - O 2. This fact has given rise to inerting systems that rely on the use of inert gases.
