Despite these problems, cement kilns have been run on pure petcoke, and a 50:50 coal:petcoke mix is a fairly normal fuel mix nowadays. The increase in the use of petcoke has of course been due to the fact that "green" coke with metals contents too high for electrochemical use became a low-cost waste by-product.

The heart of a lime plant is the kiln. The prevalent type of kiln is the rotary kiln which accounts to about 90 percent of all lime production in the world ( Ellis 1960 ). The kiln is a long, cylindrical, slightly inclined, refractory- lined furnace, through which the limestone and hot combustion gases pass counter currently.

the plant to burning only coal in Kiln #2, but DNR's Title V permit for the plant omits that requirement and, instead, provides that petroleum coke ("pet coke") can be burned. Pet coke is a much dirtier fuel than coal, which is, itself, an extremely dirty fuel itself.

Pet coke can also be used as a green and efficient fuel for combustion and power generation processes by using CaO as a sorbent of CO 2 and SO 2 …

kilns are generally preferred in terms of environmental performance. While s haft kilns are still in operation, they are generally only economically viable for small plants and are being phased out with the renewal of installations. For lime manufacture, there are 4 basic types of kilns used to

re Troubles in using petcoke. Hello Sidhant, I suspect your dusty conditions and kiln inlet ring are the result of very high sulphur recirculation as a consequence of using petcoke. Even though you may have no CO in the kiln inlet, the large amount of SO3 introduced by the petcoke may not be properly balanced by alkalis in the kiln feed.

are well known. High lime causes meal to be burned harder and refractory ITlife drops. High alkalines may cause cyclone blockage and restrict the use of the cement produced. Moisture content rises and so does energy consumption. And of course, oversize meal brings low reactivity and burnability. As leaders in kiln control and optimization using

At those temperatures, the lime is reduced by carbon to calcium carbide and carbon monoxide (CO), according to the following reaction: CaO+3C→CaC2 +CO Lime for the reaction is usually made by calcining limestone in a kiln at the plant site. The sources of carbon for the reaction are petroleum coke, metallurgical coke, and anthracite coal.
