The coking process generates the following main volatiles as byproducts coke oven gas, tar, ammonium sulfate, benzol, toluol and naphtha. A coke battery is made up of multiple ovens. Coal is crushed and blended prior to being charged in a coke oven. A larry car charges the individual oven with the blended coal.
Coking Process an overview ScienceDirect Topics. On, in the coal handbook towards cleaner production coal utilisation, wall pressure and battery life during the plastic stage of the coking process swelling of the coal mass can arise due to the inability of volatile emissions to easily escape swelling can impart pressure to the refractory walls of the slottype ovens
production at large-scale integrated blast-furnace steel plant. Since the processes use only iron ore fines and non coking-coal, FASTMET and FASMELT are expected to be the iron making processes of the 21st century, especially with the current roaring prices for lump-ore and coking-coal. 3. ITmk3R process The ITmk3 separates nugget iron and slag
With this process, the type of coal is not critical as to whether it is low, medium, or high volatile, good heat-transfer contact between the heated walls and the coal is maintained, and provision is made by wall pressure to accommodate for the swelling of the coal during coking to prevent damage to the refractory coke oven structure.
Some of the coking coal may be burned during the coke-making process because of direct COG combustion in the oven 43. 3.1.2 COG combustion for electricity In the steel industry, different surplus combustible gases can serve as potential feed stocks to generate heat and electricity for combined heat and power plants CHP.
In the Corex process, all metallurgical work is carried out in two separate process reactors the reduction shaft and the melter gasifier. Since coking and sintering plants are not required for the Corex process, substantial cost savings of up to 20 can be achieved in the production of hot metal, of a grade similar to that of the blast furnace.

iii Production There are large reserves of iron ore and non-coking coal in our country and it appears that the annual production of sponge iron will boost to 1000 million kN by the turn of the 2020. iv Raw Material for Mini Steel Plants The shortage of steel scrap has been felt by the mini steel plants spread out in the whole country.
For producing the sponge iron through this process requires high grade of iron ore and non coking coal. Gas Based DRI HBI In this process route, iron oxides are converted to the DRI HBI by using natural gas in a vertical shaft furnace.
Sponge Iron or Directly Reduced Iron DRI is produced either by using Natural Gas in a vertical shaft furnace MIDREX and HYL Process or by using non-coking coal in a Rotary Kiln. Non-availability of Natural Gas and abundant availability of non-coking coal in the eastern region led to mushrooming of rotary kiln based DRI making using coal.

Since the reserves of good coking coals are being depleted, coal preparation is necessity for a modern coke-oven plant. In addition, with the development of large capacity units in coke-making and blast furnace technology, the better quality and uniformity of feed coals has been required. 2.1 The Coking Process of Coal in the Oven Chamber
Dec 20, 2014 delayed coking process was born. This was followed in 1935 by the development of the rotary kiln cal-cining process, which is the most commonly used technology in the Western world. CPC production has increased signicantly in China over the last 10 years, and shaft calcining is the dominant tech-nology used in this region. The aluminum industry

Mar 16, 2013 Major DRI production processes are either natural gas based or coal based. Feed material for the DR process is either sized iron ore of size ranging from 10 mm to 30 mm or iron ore pellets of size ranging from 8 mm to 20 mm produced in an iron ore pellet plant. The gas based process uses a shaft furnace for the reduction reaction.
