Due to the extreme use of fossil fuels and increasing environmental problems, the steel industries have been always seeking solutions to decrease energy consumption. These efforts will not only reduce greenhouse gases (GHGs) but also decrease the costs of these industries. In this study, we investigated the effects of burners’ heating load distribution in a hot-rolling preheating furnace, by numerical modeling. This study incorporates a three-dimensional model for preheating furnaces with a given geometry and various heating loads’ distribution. Following the determination of boundary conditions, the simulation process will be carried out. This research will be evaluated in four different cases. In one case, the burners’ load distribution is uniform and in the other three cases the burners’ load distribution decreases exponentially along with the furnace. The results of this study indicate that the best scenario from a performance perspective is true, the exponential expression X−0.8 in which the energy consumption decreases up to 44 %, and the slab temperature will be reached to the given desired temperature in the furnace.

预热炉中不均匀的板坯加热模式以降低燃料消耗：通过离散纵坐标的热辐射和 k-ε 湍流模型通过半透明介质对燃烧器的负载分布影响

由于化石燃料的过度使用和日益严重的环境问题，钢铁行业一直在寻求降低能源消耗的解决方案。这些努力不仅会减少温室气体 (GHG)，还会降低这些行业的成本。在这项研究中，我们通过数值模拟研究了热轧预热炉中燃烧器加热负荷分布的影响。本研究结合了具有给定几何形状和各种热负荷分布的预热炉的三维模型。在确定边界条件之后，将进行模拟过程。这项研究将在四种不同的情况下进行评估。在一种情况下，燃烧器的负荷分布是均匀的，其他三种情况下，燃烧器的负荷分布随炉子呈指数下降。这项研究的结果表明，从性能角度来看，最佳方案是正确的，即指数表达式 X-0.8，其中能耗降低高达 44%，并且板坯温度将达到给定的炉内所需温度。
