火法炼锌厂的煤耗主要有两大部分,即用作加热炉料和供反应吸热用与作还原剂用。煤气燃烧后的高温烟气间接加热炉料,并供给还原反应所需的能量。由于碳化硅质炉体及陶土质炼罐的传热系数很低,被吸收的热量是极少部分,大量的热能则随着烟气 Fire method smelter coal consumption has two major parts, namely for heating the charge and for the reaction with endothermic and for reducing agent. Gas fired high temperature flue gas indirect heating charge, and supply the energy required for the reduction reaction. Due to the low heat transfer coefficient of the silicon carbide furnace and the clay refining tank, a small amount of heat is absorbed and a large amount of heat energy is dissipated along with the flue gas
