摘要
提出了立式烟道环式炉的动态两维数学模型。侧重分析了主要的热平衡要素。对于热源(燃料、挥发分、填充料焦)、热耗(气体、砖、焦炭、阳极以及通过炉盖、侧墙和炉底的热损失)都与气体渗透和气体质量流一起加以考虑。对于一套给定的运行及设计参数,确定了热平衡、温度分布、渗透程度、气体成分及燃烧消耗。讨论了模型特点和性能。在标准炉子火焰周期下得到的结果与澳大利亚Boyon熔炉有限公司(BSL)现场测量值进行了对比。
A transient two-dimentional model of a vertical flue ring furnace is presented. Emphasis is laid on the main heat balance elements. Heat sources (fuel, volatiles, packing coke) and heat sinks (gas, brick, coke, anode and losses through cover, sidewall and foundation) are all considered together with air infiltration and gass mass flow. Heat balance, temperature distributions, gass composition, infiltration levels, fuel comsumption are determined for a given set of operation and design parameters. Model characteristics and capabilities are discussed. Results obtained for a standard furnace fire cycle are compared with on site measurements made at Boyne Smelters Limited (BSL), Queensland, Australia.
