Nov 10, 2000· In order to reduce the cost of running blast furnaces (BFs), injected pulverized coal is used rather than coke to fire BFs. As a result of this, unburned fine materials are blown with the gas into the bosh and dead man areas with possible detrimental effects on gas flow and permeability of the coke column. The capacity of the furnace to consume these particles by solution loss is probably one ...

The Blast Furnace is a membersonly minigame situated in Keldagrim for smelting bars. The furnace here only requires half as much coal when smelting usually, so it can be useful when smelting the ores that require more coal.

Also by producing less coke, more time would be available for repair and rebuilding of existing batteries. Coal injection started at Taranto blast furnaces Nos. 4, 2, 5 and 1 in September, October, November, 1991 and January, 1992 respectively. A central grinding and injection station supplies coal to the blast furnaces.

Pulverized Coal Injection (PCI) System for Blast Furnaces. In the past, reactions within the blast furnace were stimulated by injecting heavy oil, as auxiliary fuel, along with the blasts and oxygen. The heavy oil was replaced by pulverized coal after the oil crisis. This made it possible to use cheap coal, such as noncoking coal.
