摘要: 介绍了一种炼焦煤性价比评价模型建立的新方法,该方法在焦化企业炼焦煤性价比常规测算的基础上, 增加了不同炼焦煤挥发分对煤气产生量的影响,同时还考虑了对高炉经济指标的影响。通过取一单种煤作为标 准煤种,将其对应的焦炭指标作为标准,将其他煤种所得焦炭质量指标与这一标准进行比较,用对高炉的影响 程度表征这一比较值。将对高炉的影响程度体现在焦炭成本上,最终用不同焦炭对应的焦炭成本表征出不同单 种煤的性价比。

Abstract: The method is based on common calculation of cost-performance of coking coal in conventional coking enterprises,adding the impact of volatiles of different coking coal on gas yield. And the influence on economic index of blast furnace is also taken into account. Take an individual kind of coal as the standard coal,and indicators of the corresponding coke as standard indicators, then compare the indicators of coke from other kinds of coal with the standard indicators,with the comparison value shown in terms of influencing degree on blast furnace. And the cost of coke is used to indicate the influencing degree on blast furnace. And coke cost of different kinds of coal is used to indicate the cost-performance of each individual kind of coal.

Key words: Coking coal, Cost-performance, Evaluating model
