Coke Dry Quenching Industrial Efficiency Technology

Coke Dry Quenching Industrial Efficiency Technology

Coke Dry Quenching (CDQ) is an alternative to the traditional wet quenching of the coke. Coke is cooled using an inert gas in dry cooling plant, instead of cooling by sprayed water which results in high CO 2 emissions and thermal energy loss. This process allows the recovery of the thermal energy in the quenching gas which can then be used for the production of steam and electricity, for ...

AIST 2018 AISTech Conference Proceedings

Abstract Coke Dry Quenching (CDQ) technology helps not only in recovering almost 80% of the sensible heat of the red-hot coke post the coke-making process, but also contributes in improving coke quality, thereby enhancing BF productivity. The G blast furnace at Tata Steel uses 100 percent dry quenched coke in the burden.

How a Coke Plant Works GASP

How a Coke Plant Works GASP

Oct 04, 2018 How a Coke Plant Works. Coal is the main ingredient used to make coke. Iron is produced by inputting coal into a blast furnace. However, coal cannot be put directly into a blast furnace because of all the harmful by-products that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first.

Abstract. A comparison of DQ-coke (dry quenched coke) with WQ-coke (wet quenched coke) for blast furnace operation was made. The results were as follows a decrease in coke moisture caused a sharp rise in the top gas temperature a decrease in coke moisture fluctuation was confirmed, and it is estimated that DQ-coke contributes to reducing furnace heat fluctuation coke size distribution on ...
