高炉喷吹不同煤粉时的效益比较

Comparison of benefit brought by different pulverized coal injected into the blast furnace

喷吹不同的煤粉对高炉冶炼经济效益的影响主要有2个方面,其一是煤粉本身费用(包括运输,加工费用在内 )的变化 ;其二是炼铁焦比 ,高炉产量的变化所产生的效益 本文提出了更换煤粉时对生铁成本、经济效益影响的计算方法及算式 。

The influence of different pulverized coal injected into the blast furnace on the economic benefit comes mainly from two aspects:First,the costs of pulverized coal(including expenses of transportation and processing);second,benefit brought by influence of different pulverized coal injection on coke ratio and blast furnace production.The calculation formula for benefit comparison of different PCI is given.It is of great use for choosing pulverized coal.
