炼锌因工艺方法不同而耗能各异,详见表1。我国由于设备陈旧,管理不细,炼锌能耗比较高,净耗指标相当于先进国家的1.3倍以上,浪费多,节能潜力很大,降低能耗已是当务之急。本文主要讨论竖罐炼锌能耗现状、节能途径和潜力。 1.竖罐炼锌工艺和耗能特点 Smelting due to different processes and energy consumption, see Table 1. Due to obsolete equipment and poor management, China’s energy consumption is relatively high. The net consumption index is equivalent to more than 1.3 times that of the advanced countries, resulting in a great waste of energy and great potential for energy saving. It is imperative to reduce energy consumption. This paper mainly discusses the energy consumption of vertical tank zinc smelter, energy-saving ways and potential. 1. Vertical tank zinc smelting process and energy consumption characteristics
