The small-scale kiln (Figs. 1 & 2) used is a scaled-down version of the larger Experimental Lime Kiln, located at Charlestown in Fife, Scotland, details of which are given elsewhere (Hughes et al. 2002) The smaller kiln is located at the same site. The large kiln has an internal shaft of 4.8m height and 1.8m in diameter and can hold
natural gas and fuel oil used in lime kilns. Due to the high vanadium and sulfur contents in petcoke, there had been concerns over the impact of burning petcoke on kiln and chemical recovery operations. Laboratory studies were performed to examine the fate of vanadium and sulfur in lime kilns and chemical recovery cycle.

"Import of pet coke is allowed for only cement, lime kiln, calcium carbide and gasification industries when used as feed stock or in the manufacturing process on actual user condition", said ...
Two other lime kiln concerns that have been expressed are ring formation and reduced refractory life due to the vanadium content of the pet coke. Burning pet coke will aggravate ring and ball formation. The sulphur is oxidized to SO2 and reacts with lime and residual sodium (which readily converts to Na2O in the kiln) to form CaSO4 and Na2SO4.
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...

High Sulphur pet coke is used as a fuel for burning in various or different kinds of furnaces, kilns, and boilers. It is also used as a fuel in the metal, brick industries, refractory, cements, textiles, plywood manufacturing units, hard coke calcinations units, lime stones, chemical plants, glass manufacturers, silk mills, rolling plants ...
QUANTITIES OF BURNT LIME. A PFR kiln (parallel flow regenerative shaft kiln) con-sists of two vertical shafts and a connecting cross-over channel. Both shafts work with each other. While one calcines the product, the other preheats the stone. In the burning shaft the lime is calcined in parallel flow. The hot combustion gases are then
* An important factor influencing the rate of combustion is the specific surface area of the fired pet-coke. So, the fineness of pet-coke is increased to improve its burning behaviour. * Based on the experience of other plants, pet-coke fired in cement kiln and calciner is …
