高炉碳排放量影响因素讲述.doc

毕业设计（论文） 题 目 高炉碳排放量的影响因素分析  摘 要 高炉炼铁流程所排放的CO2是钢铁企业中温室气体的主要来源，而高炉生产排放的CO2主要来源是焦炭和煤粉，因此，减少碳排放量，一方面对冶金行业来说具有降低燃料比的经济意义，另一方面，这也有利于环境保护，减缓当下全球环境变暖问题的脚步。 本文将高炉煤气中CO与CO2的总量作为高炉碳排放量，用冶炼1t铁水产生的CO和CO2总体积表示碳排放量，在一定原料条件和冶炼参数的基础上，借助物料平衡计算与热平衡的计算，主要绘制并分析了焦比与碳排放量，以及铁水w(si)与碳排放量的关系图，得出碳排放量与影响因素间的定量定性关系：焦比每增大10kg/t，高炉碳排放量大约上升16.3m3/t左右；铁水w(si)的百分数每上升0.1，碳排放量增多量在2.0左右，增幅较小。分析结果表明，在满足实际能力与生产要求的情况下，合理地减少焦比，降低铁水w(si)将有利于钢铁企业顺应当下的减缓全球气温上升的趋势。 关键词：高炉 碳排放 焦比  ABSTRACT CO2 emissions from blast furnace iron-making processes are the main sourcesof greenhouse gases in iron and steel enterprise .and The main source of CO2 emissions from the production of blast furnace coke and coal. therefore,to reduce carbon emissions,on the one hand,ithis have a lower fuel economy than the significance of the metallurgical industry.on the other hand,This will also be conducive to environmental protection, slow the currentpace of global warming . This total amount of CO and CO2 in blast furnace of blast furnace gas carbonemissions ,Useing 1T of smelting iron CO and CO2 of the total volume of carbon emissions,On the basis of certain raw materials and metallurgical parameters By calculation of material balance and thermal balance calculations ,And analyzes the main draw of the coke and carbon emissions,As well as hot metal silicon content with carbon emissions diagrams,and the qualitative relationship between them is obtained through mass balance and heat balance calculations，Focal ratio increases 10kg/t, blast around about rising carbon emissions16.3m3/t; w of molten silicon content increased by 0.1 percent each, and carbonemissions at about 2.0 per cent, an increase of smaller，Results indicate that, in the case of real capacity and productionrequirements are met, reasonably reduce the coke rate, lower hot metal w(si) will be conducive to the iron and steel
