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.
WhatsApp: +86 18037808511As the grinding capacity of the coal mills lowers by 50% to 80%, there should be adequate coal grinding capacity after use of the petcoke. 3. If at a certain level of use of petcoke, system is not capable of its proper burning (as indicated by the CO contents higher than %), then its quantity cannot be increased further.

WhatsApp: +86 18037808511Petcoke is like coal, but dirtier. Petcoke looks and acts like coal, but it has even higher carbon emissions than already carbonintensive coal. On a perunit of energy basis petcoke emits 5 to 10 percent more carbon dioxide than coal. A ton of petcoke yields on average percent more CO2 than a ton of coal. The proven tar sands reserves of ...

WhatsApp: +86 18037808511Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...
WhatsApp: +86 18037808511The 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. ... Steel balls within the unit crush the ...

WhatsApp: +86 18037808511More than 50% of its weight is made up by carbon. Therefore it is classified as highrank coal. Other fossil fuels like subbituminous coals with high moisture contents as well as brown coal and lignite are lower ranked. Lignite, which is the lowest ranking fossil fuel, is defined between peat and hard coal. Petcoke is not a natural product.
WhatsApp: +86 18037808511Typical analysis of Pet coke verses other available coal is given in tableI Normally volatiles help for initial ignition. Therefore to burn low volatile fuel, it needs more surface area (Finer grinding). After some trial, it was decided to keep fineness of firing coal % retention on 90 micron. But existing coal mill was
