Introduction of high quality coke to a blast furnace will. result in lower coke rate, higher productivity and lower hot metal cost. COKE PRODUCTION. The cokemaking process involves carbonization of coal to high temperatures (1100°C) in. an oxygen deficient atmosphere in order to concentrate the carbon.

Coal, of course, is the fuel mined directly from the ground, while coke is a form of coal that's been heated in the absence of air and is most frequently used in iron ore smelting. Fly ash, on the other hand, is the byproduct of burning coal – the particulate that used to go up the chimney with flue gases but is now trapped and collected, due to tougher air pollution regulations.

Oct 04, 2018· Coal is heated to about 1250 degrees Celsius in the coke ovens. This process is referred to as 'dry distillation' because these coke ovens are oxygen free, so the coal does not actually burn. This process takes around 18 hours to convert 35 tons of coal into 25 tons of coke. After heating up the coal into coke, the coke is then unloaded from the oven by a pusher machine.

Jul 16, 2014· Metallurgical coke, or met coke, is manufactured from blends of bituminous coal in a heated distillation process resulting in a nonmelting carbon. Coke is made by one of two processes: byproduct or nonrecovery, also known as heat recovery. In byproduct coke making, impurities are driven off the coal in order to leave nearly pure carbon.
