熔炼炉燃烧参数控制

Combustion Parameter Control in Smelting Furnace

铝和铝合金熔炼是铝加工企业生产中的第一道重要工序,而铝熔炼炉是铝熔炼的关键设备,也是工厂中主要能耗设备,在生产能耗中占有很大比例,一些企业铸轧板材生产中其燃料消耗达到总能耗的50%左右。本文从铝及铝合金熔炼炉燃烧控制参数——天然气流量、助燃风流量、天然气和助燃风比例、炉压、排烟温度——等方面对能耗的影响及之间的相互影响和我厂在各参数控制方面的经验进行综合论述,望能够供同行参考。

Aluminum and aluminum alloy smelting is the first important procedure in fabricating factories. Moreover ,aluminum melting furnace is the key equipment in the smelting and the main energy consumption facilities. Aluminum smelting furnace occupies high proportion of energy consumption. For example ,the fuel consumed in a furnace is about 50% of general energy consumption in some enterprises who produce cast--rolling plate. This paper expatiates on the aluminum and aluminum alloy combustion control parameter-- the gas flow, the combustion air flow, air - gas delivery ration, furnace pressure, exhaust temperature on the influence and the energy consumption of the interaction between various parameters.
