Aug 01, 2006 · The air/coke mix is metered through the manifolds to various firing zones on top of the kiln. In a tunnel kiln firing clay brick, petroleum coke can typically be used beginning at about 1400°F (760°C), with a resulting overall kiln fuel mix of about 70% coke and 30% natural gas. Two variations of the coke firing system exist.Get Price
Petroleum Coke as fuel Fouling has been seen with boilers firing petcoke −However, Anthony and his co-workers have unequivocally shown this is a low ash and not a V problem −V is always associated with Ni at a constant V:Ni ratio and always present as Ca vanadates[PDF]Get Price

The petroleum green coke is fed into a refractory lined rotary kiln where the volatiles are driven off during the calcining process in an oxygen deficient atmosphere. Air can be injected through the kiln shell to burn a portion of the volatile matter in the kiln providing usable heat to the kiln.Get Price
Eight commercial fly ash samples including two from petroleum coke/coal co-firing were characterized to determine the origin, structure, and properties of the unburned carbon. Because of its relevance to ash utilization, the characterization included measurements of adsorptivity toward concrete surfactants, and its dependence on carbon form, particle size, and contact time.[PDF]Get Price
Co-firing petroleum coke and coal in circulating fluidized bed (CFB) is an ideal solution for those problems. Emission characteristic of gaseous pollutants from co-firing petroleum coke and coal is investigated in the paper. Experiments were carried out in a 0.6 MWt pilot-scale CFB combustor with the total height of 12m from the air distributor ...Get Price
Aug 01, 2006 · Firing with Petroleum Coke About 85 heavy clay manufacturing plants are currently operating worldwide using petroleum coke as the primary fuel in tunnel kilns. Spain has been the pioneer with an advanced firing system* using this waste product. Aside from being a proven technology, the firing system is simple, reliable and clean.Get Price
May 03, 2001 · Petroleum coke utilization for cement kiln firing Abstract: Pulverized delayed petroleum coke imported from the USA is the prime energy source for both 5000 MTPD modern dry process clinker lines operating in the Nesher Israel Cement Enterprises' Ramla plant.
May 03, 2001 · Both the first line-RDL-1-operating since 1995 and the second one-RDL-2-operating since 1999, were designed and guaranteed for firing of eighty percent of energy as petroleum coke, the rest being bunker C heavy fuel oil.Get Price

- Unique Fuel feeding system to prevent back firing - Compact & user Friendly - Very Low Running Cost. The Petroleum Coke also known as Petcoke, has several remarkable features from the usage point of view that are: Petcoke can be a good replacement of coal/lignite. It can be used in blend form along with coal/lignite or in AFBC/CFBC boilers.Get Price
Petroleum coke firing in a circulating fluidized bed boiler has sometimes been reported to be associated with cyclone deposit problems and return leg plugging. In this paper, we present data which indicate that some of these problems may be due to the calcium-rich bed material used during the firing.

The constraints on PC cofiring of petroleum coke are more significant than in the case of cyclone firing. For all pulverized coal units, the Hardgrove grindability index (HGI) becomes critical because pulverizing petroleum coke to an appropriate size (e.g., 80% < 200 mesh [74 μm]) may be uneconomical for certain petroleum cokes with low HGI values.Get Price
However, petcoke can be used concurrently with coal in many power plants, a practice known as co-firing. Some technical challenges associated with co-firing exist (from petcoke's high sulfur content, for example), but the very low price of petcoke could be an important factor to keep coal plants open in an economically competitive energy environment.Get Price
