Coke production

GIPROKOKS executes complex designing of coke oven plant facilities: coke oven batteries for production of blast furnace and foundry coke; ovens for production of special kinds of coke; pushing emission control systems; coke dry cooling plants; coke wet quenching complexes; coke transportation, handling, screening, uploading and storage facilities; coal towers; garages for repair of coke oven machines; hangars for erection of coke oven batteries brickwork; refractories, materials and equipment storage.

Details
Coke dry cooling plant

GIPROKOKS is the founder of state-of-the-art technology of coke dry cooling. The widespread tightening of environmental standards and the need to introduce energy-saving technologies of high quality coke production alongside the deterioration of coking coal feedstock base predetermine the priority of coke dry cooling for the near future.

Coke oven batteries for carbonization of stamped coal blend

GIPROKOKS has successfully implemented the technology of preliminary stamping (coal blend stamping) which is increasingly used to produce coke from coal blends with an increased content of lean-caking  coals up to 65% (conventional technology provides up to 35%). The essence of the process is the compaction of coal grains during stamping. This assists to improve coking of coal during carbonization and to produce coke of high mechanical strength.
