Characterisation of Carbons Formed in Coal-injected Blast Furnaces : 9783639163841 : 04 Jun 2009 : Blast furnace is the dominant route for iron-makingworldwide. Coal injection into blast furnaces tosubstitute for some of the metallurgical coke becomeswidely practiced because of the increasing price ofmetallurgical coke and need to reduce theenvironmental impact of the coke-making process.However, coal injection at rates higher than 200 kgcoal/tonne of hot metal, which are still less thanthe theoretical limit, has been often found to causefurnace operational problems. Whilst many researchefforts have already been made , the fate ofinjectant coal in the furnace is still not fullyunderstood. The extent of coal consumption cannot beregularly measured either at present. This bookintroduces our research work to gain a betterunderstanding of coal consumption in blast furnacesand to develop analytical methods for fasterestimation of the consumption extent. In particular,a quantitative method b
