喷枪顶吹熔炼技术的进展传统熔炼有鼓风炉熔炼、反射炉熔炼、电炉熔炼等。传统熔炼流程技术成熟、可靠,简易灵活,设备结构简单。但传统熔炼流程的生产效率低;脱硫率低,硫的回收率低,烟气含SO2浓度很低,低浓度二氧化硫烟气处理费用高,环境污染严重,劳动强度大,生产条件差;燃料率 The progress of the gun top blowing smelting technology Traditional smelting blast furnace smelting, reflex furnace smelting, smelting and so on. Traditional melting process technology is mature, reliable, simple and flexible, simple equipment structure. However, the traditional smelting process has low production efficiency, low desulfurization rate, low sulfur recovery rate, low SO2 concentration in flue gas, high flue gas treatment cost for low concentration SO2, serious environmental pollution, heavy labor intensity and poor production conditions. The fuel ratio
