The coke oven by-product plant is an integral part of the by-product cokemaking process. In the process of converting coal into coke using the by-product coke oven, the volatile matter in the coal is vaporized and driven off. This volatile matter leaves the coke oven chambers as hot, raw coke oven gas. After leaving the
For a more detailed description of the coke production process and coke ovens, the reader is referred to the previous IARC Monograph (IARC (2010). In 1990, total worldwide coke production was about 378 million tonnes, a production volume that had remained essentially unchanged since 1970.

12.2 Coke Production 12.2.1 General Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygen-free atmosphere (–coked–) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke.
A coke oven battery is a group of ovens in which coal is heated to extremely high temperatures in the absence of air. This process concentrates the carbon in the coal to produce coke. Coal is processed into coke in large batteries of ovens before entering a blast furnace.
Jun 26, 2019· In the coke-making process, treated coal is placed in the coke oven. Due to the high temperature inside, coal gas, coal water, and tar are separated from the coal. The gas and water then fuse together with carbon and the remainders of ash. The hard residue that remains at the end of this process is commonly referred to as coke.

Brief process description. 1 The coke oven is designed for the destructive distillation of 'coking' coals in order to produce metallurgical coke, usable 'by-products', eg ammonia, coal tar, benzol, naphthalene and ammonium sulphate and coal gas.
Oct 18, 2015· PPT ON COKE PREPARATION 1. PRESENTATION ON PREPARATION OF COKE By:- SUKESH KUMAR B.TECH 4TH YEAR METALLURGICAL & MATERIALS ENGG. PREAPARATION OF COKE IN COKE OVENS BATTERIES 2. • The main function of Coke Ovens is to convert coal into coke which is used as a fuel and reducing agent in the Blast Furnace.
A coke oven battery is a series of 10 to 100 coke ovens operated together. Figure 12.2-1 illustrates a byproduct coke oven battery. Each oven holds between 9 to 32 megagrams (Mg) (10 to 35 tons) of coal. Offtake flues on either end remove gases produced. Process heat comes from the combustion of gases between the coke chambers.
The non-recovery process is a well-established, cost-effective, and environmentally friendly metallurgical coking process. The FDS Coke Plant's design incorporates an improved iteration of existing non-recovery coke plant technology that includes a number of technological advances.

Jul 16, 2014· In non-recovery or heat recovery coke making, ovens are stacked in a "beehive" form. The ovens are heated from the top, and air is fed through the bottom for combustion through chambers located in the oven wall. The waste gases are not sent to recovery plants, so this process is known as "non-recovery" coke making.
