Comparison of Byproduct and Heat-Recovery Cokemaking Cokemaking flowsheet. oven, and coke is formed by the destructive distillation of coal at temperatures of approximately 1,100°C and higher. At the end of the coking cycle, the hot coke is pushed from the oven into a quench car, which trans- ports it to the quench tower to cool and stabilize the coke. Kress Indirect Dry Cooling System: Bethlehem Steel's Coke Coke Oven Batteries A typical by-product coke oven battery consists of 50 to 80 slot ovens. Each oven is charged from the top with coal specially blended for metallurgical coke production. This coal is pyrolyzed by heat- ing the sidewalls of these narrow ovens to about 1150 C for 16 to 48 hours. What is the difference between recovery and non-recovery Jun 13, 2016 · Answer Wiki. Short and simple answer to this question would be - a recovery coke oven recovers the other by-products (products other than coke) that are formed during the formation of coke from coal, while a non-recovery coke oven do not recover such by-products. Most coke ovens in India (those designed by the Chinese companies)...
Jul 16, 2014 ... In by-product coke making, impurities are driven off the coal in order to leave ... the coal at about 1800-3600 degrees Fahrenheit in large slot ovens which ... This type of coke making is then called "heat recovery" coke making.
Coke Oven By-Product Plant. The coke oven by-product plant is an integral part of the by-product coke making process. During the production of coke by coal carburization in a coke oven battery a large amount gas is generated due to the vaporization of volatile matter in the coal. Coke From Illinois Coals, an Experimental Slot-Type Oven ...

Excerpt from Coke From Illinois Coals, an Experimental Slot-Type Oven Midwestern by-product coke ovens require annually millions of tons of high volatile bituminous coals Which are shipped from the Appalachian coal fields in West Virginia Technical & Commercial Advantages of Accelerated Heatup of ... world. Rather than collecting the by-products of coke production as in the conventional slot oven design, heat recovery ovens incinerate the by products, and may (or may not) utilize the waste heat to generate steam which is then used, in many cases, to drive turbines and produce electricity. This type of coke battery typically consist of 20

1. Introduction. Coke oven gas (COG) is a by-product in the cokemaking process. In conventional cokemaking process (slot-type coke ovens), approximately 70 mass % of coal is converted into solid (coke) and 30 mass % into gas (COG) and liquid (tar), where tar accounts for a few mass %. COKE PRODUCTION - monographs.iarc.fr Coke-oven gas is a valuable heating fuel that is used mainly within steel plants, for example, to fire blast-furnace stoves, to soak furnaces for semi-finished steel, to anneal furnaces and lime kilns as well as to heat the coke ovens themselves (Kaegi et al., 1993). Coke is mostly produced from slot-type by-product coke ovens.

Larry-Car-Free Charging of Coke Ovens ----- V. LARRY-CAR-FREE CHARGING OF COKE OVENS The high-fluidity characteristics of preheated coal and the necessity of minimizing the loss of heat during transport from the heating units to the ovens have resulted in the development of two systems that are used to charge coke ovens without the use of larry cars. Additional Use of Coke Oven Gas | Industrial Efficiency ... Coke oven gas with a heating capacity of 6 to 8 GJ can be recovered for every ton of coke produced. (IEA, 2007) In China, the potential of recovering COG from stand-alone coke enterprises was estimated to be around 250 PJ in 2005. Coke Oven Machine for Factory Automation (FA) Plant System
