高效低氮低动能全氧燃烧器在玻璃行业的应用研究

Research on Application of Oxyfuel Combustion Burner with High Efficiency, Low Nitrogen and Low Kinetic Energy in Glass Industry

针对常见全氧燃烧器火焰覆盖面积小、火焰局部温度过高,对玻璃、耐火物冲刷严重、燃烧产生的NO_(X)含量偏高等问题,通过对烧枪及烧嘴砖的结构再设计,达到火焰更柔和、覆盖面积更大、对玻璃冲击及耐火物的冲刷更小、NO_(X)初始排放值更低的目的。该系列烧枪经过在杭州三星工艺玻璃有限公司实际应用,综合性能达到设计能力要求,同时在节能及排放方面也有相应的改善。

In view of the following flame disadvantages of the common oxyfuel combustion burner, such as small coverage area, too high local temperature, serious erosion to glass and refractory, slightly high content of NO_(x) from combustion, the burner is transformed. After structure redesign of the burner and the nozzle block, the flame is softer, its coverage area is broader, erosion to glass and refractory is reduced,initial discharge value of NO_(x) is lower. After practical application in Hangzhou Samsung art glass Co., Ltd.,the comprehensive performance of the burners meet the requirements of design capacity, and there are corresponding improvements in energy saving and emission.
