BLAST FURNACE MODELING An implementation of Rist and Meysson (1967) blast furnace process model was used to investigate the impact of PCI coal quality on the operation of a blast furnace. This model examines: The fuel rate which closely relates to the heat balance in the lower part of the furnace and gas (indirect) reduction rate at the shaft.
This gas is used for the furnace mills, in gas engines and for electricity and steam generation. Often, in the steel industry, blast furnace gas is used as an accessional to natural gas (Bojic and Mourdoukountas, 2000). Blast furnace gas deposits adhere firmly therefore, boilers using these type of fuel should be frequently cleaned.
Coke ovens, Blower house, Blast furnace, EAF, and the BOF are on 4'' long slabs, the rolling mill is on a 8'' long slab. Total length amounts to about 28'' and then a transfer yard of TBD length, although to be functional it would probably be 20'' long.
Jan 29, 2016 · Air Blast System for Blast Furnace. A blast furnace (BF) produces liquid iron (hot metal) by the reduction of ore burden with reducing gases.
