双P型及W型辐射管系统性能分析及测试

对W型和双P型辐射管加热系统的烧嘴结构及燃烧方式进行了分析,对比测试了两种辐射管加热系统的烟气循环率、管壁温度均匀性、燃料利用率、NO_x等关键技术指标。结果表明,双P型辐射管燃烧系统管壁温度均匀性更好,节能效果显著,且可以采用更大的烧嘴功率,减少辐射管加热系统和控制模块的数量,降低投资成本,具有较大的推广应用价值。

Performance analysis and test of D-P type and W type radiant tube system

Burner structures and combustion modes of W-type radiant tube system and dual P-type radiant tube system were analyzed,and the key performance indicators of the two kinds of radiant tube heating systems were tested and compared,including flue gas circulation rate,temperature deviation,fuel efficiency and NO_x.The results show that the dual P-type radiant tube combustion system has greater value of popularization and application,because it has better uniformity of tube wall temperature,remarkable energy saving effect,and the ability to use higher power burner to reduce the number of heating system and control module and to reduce the investment cost.
