What is Coking Coal - Aspire Mining Limited

What is Coking Coal. Coking coal, also known as metallurgical coal, is used to create coke, one of the key irreplaceable inputs for the production of steel. There are many varieties of coal in the world, ranging from brown coal or lignite to anthracite. The property that really sets coking coals apart from other coals is its caking ability, which is the specific property required in order to ...

How is Steel Produced? World Coal Association

The coking process consists of heating coking coal to around 1000-1100ºC in the absence of oxygen to drive off the volatile compounds (pyrolysis). This process results in a hard porous material - coke. Coke is produced in a coke battery, which is composed of many coke ovens stacked in rows into which coal is loaded. The coking process takes place over long periods

Instead of being heated by vertical flues, the coal mass is heated from the bottom flues and the gas that is evolved is used to heat the coal mass from the top (see Figure 1‐3). The unique feature of heat recovery batteries is operation with a negative pressure and combustion of the waste gas to recover the waste heat to produce steam and electricity or both. Operation of the

Non Coking Coal for Iron Production – IspatGuru

Non-coking coal, which can be used in Corex/Finex process, is to meet certain physical, chemical and high temperature properties for stable process and to attain high performance levels. The coal used in the Corex/Finex processes is required to supply heat for the devolatilization of the coal, the gasification of the char, and the melting of the reduced iron from the reduction shaft

Coking - an overview ScienceDirect Topics

Delayed coking process is a thermal process which increases the molecular aggregation or association in petroleum-based residues or coal tar pitches leading to extended mesophase domains. This is achieved by holding them at an elevated temperature (usually 750 K–765 K) over a period of time (12 to 36 h). It is performed in a coking drum and is designed to ultimately
