摘要

当煤用作燃料时,较高的热值(HHV)对煤的质量非常重要。它通常用于估计处理和其他选矿方法的效率,并用于研究目的。尽管这是一个成本高昂的过程,需要特殊的设备和专家来操作。然而,使用普通马弗炉可以很容易地获得近似分析数据。因此,为了简化任务并降低分析成本,开发了许多相关性,用于从煤的近似分析中确定HHV。在目前的工作中,已经努力开发一种基于近似分析数据的相关性,用于计算煤的HHV(风干基)。本文提出的模型是通过对50个本地煤样本的分析建立的,其重要性在于影响HHV的所有主要变量的作用。所开发的模型似乎比现有模型更好,并具有以下特性:模型1:HHV(Mj/kg)=15.788“0.215M%”0.148A%+0.036V.m%+6.680 F.c%模型2:HHV(Mj/kg)=8.804““用经验公式测定和计算了0.061M%+0.187V.m%+0.231F.c%的基本煤种的热值,并对其结果进行了比较。分析的50个样品的热值存在显著差异。认为进一步研究这些类型的煤种有利于更好、更经济地利用煤。”在接近煤含量的热值之间也观察到显著的相关性。

Development of correlation between GCV and proximate analysis of indigenous coals
Higher heating value (HHV) is very important for quality of coal when used as a fuel. It is often used for estimating the efficiency of treatment and other beneficiation methods and for research purpose. Although it is a costly process and requires special equipment and experts to operate. Whereas proximate analysis data can be obtained easily using an ordinary muffle furnace Therefore, to simplify the task and to reduce the cost of analysis many correlations were developed for determining HHV from proximate analysis of coal. In the present work, an effort has been made to develop a correlation based on proximate analyses data for calculating HHV of coal (air-dried basis). The models presented here is established using analyses of 50 samples of indigenous coal and its importance lies in role of all the major variables affecting the HHV. The developed models appear to be better than the existing models and have the following: Model 1: HHV (Mj/kg) = 15.788– 0.215M% – 0.148A% + 0.036V.m% + 6.680 F.c% Model 2: HHV (Mj/kg) = 8.804 – 0.061M% + 0.187V.m% + 0.231F.c% Heating values of basic types of indigenous coal samples were measured and calculated using empirical formulae and results were compared. Remarkable differences were observed in heating value of fifty samples of indigenous coal analyzed. It is determined that further study of these other types is merited for better and more economical utilization of the coal. A significant correlation was also observed between the Heating values proximate contents of the coal.
