摘要

熔炼还原容器(SRV)在熔炼过程中烟气温度高，而铁水温度低。因此，SRV上下区域之间的换热效率需要进一步提高。研究了SRV内部的流体流动和换热特性，得出了SRV内部的质量分数、温度分布和气体运动。模拟值与实测值的误差稳定在5%以内。SRV中心的气体呈现高速涡旋流动。燃烧反应主要发生在炉膛中央。由于炉内传热主要受气流影响，因此高温区呈u型分布，主要分布在区域中心、氧枪出口和炉壁附近。

Simulation of the flow, temperature, and concentration fields in the reactor of the HIsmelt process

ABSTRACT The flue gas temperature of the Smelting Reduction Vessel (SRV) in the HIsmelt process is high while the temperature of the molten iron is low. Therefore, the heat transfer efficiency between the upper and lower regions in the SRV needs to be further improved. The fluid flow and heat transfer characteristics inside the SRV were studied to derive the mass fraction, temperature distribution, and gas motion. The error between the simulated and measured values remained stable within 5%. The gas in the centre of the SRV shows a high-speed vortex flow. The combustion reaction mainly occurs in the centre of the furnace. Since the heat transfer in the furnace is mainly influenced by the gas flow, the high-temperature zone shows a U-shaped distribution and is mainly around the centre of the region, the oxygen lance outlet, and the furnace wall.
