新型蓄热式烧嘴在轧钢加热炉上的应用及改进

新型蓄热式烧嘴增大了蓄热体换热面积,采用了多孔射流板技术并在烧嘴入口增设了导流板,石横特钢加热炉应用这种烧嘴,主要技术经济指标大幅度提升,加热能力提高27%～33%,燃料消耗降低13%～14%。通过对烧嘴结构的进一步优化改进,实现了射流板的炉外更换和蓄热体的在线更换,可延长烧嘴的使用寿命至10a。

Application and Improvement of New Type Regenerative Burner in Rolling Heating Furnaces

New type regenerative burner increased the heat exchange area of the regenerator, adopted multiorifice fluid plate technology and added guide plate in the burner entrance. Shiheng Special Steel applied this burner in the heating furnaces. Then main technical and economic indexes improved significantly： the heating ability increased by 27% or 33% and the fuel consumption reduced by 13% or 14% . Through optimizing and improving the structure of the burner, the multiorifice fluid plate realized out-of-furnace replacing and the regenerator online replacement, can prolonging the service life of the burner to 10 years.
