装炉煤挥发分装炉煤挥发分volatile matter of coal chargezhuanglumei hujfafen装炉煤挥发分(volatile mette:of coal。恤rge)装炉煤质量控制指标之一。指在规定条件下隔绝空气加热装炉煤时，挥发性有机物质的产率。挥发性有机物质是煤加热分解的产物，而不是煤中固有的成分。它对焦炭的质量以及焦炉煤气和炼焦化学产品的产率有直接影响。装炉煤般是由两种以上结焦性不同的炼焦用煤配合而成的。(见配煤)各种炼焦用煤的热解产物能够相互发生化学反应，所以，装炉煤挥发分理论上并不等于各原料煤挥发分的简单加和，但挥发分的测定是在隔绝空气下快速加热进行的，煤样在350一550℃温度区间内停留的时间很短，而热解产物间的化学反应均属有机化学反应，反应速度较慢，致使各原料煤挥发分之间的交互作用不显著。因此，装炉煤的干燥无灰基挥发分不谧‘与各原料煤的干燥无灰基挥发分I一daf之间存在以下关系:「*一二X.(「瓜，)式中X、为原料煤!的配比。控制目标在装炉煤粘结性指标保持一定的条件下改变各原料煤的配比，可导致挥发分变化。装炉煤挥发分高，则焦炭机械强度和块度减小，焦炭气孔率和比表面积增大;而焦炉煤气和炼焦化学产品的产率提高。煤焦油产率I、粗苯产率I一和焦炉煤气产率z，与装炉煤干燥无灰基挥发分fdaf间的关系可用下列经验公式表示:X一18.36+1.531袖一0.261、af Y~一1 .6+0.144V‘一0.0016V益z一。寸元;式中。为系数，对气煤a一3，对焦煤a~3.3。上述经验公式适用于I，da吏一20一30%的装炉煤。从兼顾焦炭质量以及焦炉煤气和炼焦化学产品产率出发，各国通常将装炉煤挥发分控制在28一32%范围内。生产大型高炉用焦炭时，装炉煤挥发分控制为V‘~26一28%。调节措施主要是调整炼焦煤的品种和各种煤的配比。调整品种和调节配比时，要保证装炉煤灰分、硫分和粘结性指标处于控制范围内。(刘述棋)
