Embodiment Construction
[0025] Such as Figure 1-7 The axial swirling stepless adjustable low-nitrogen burner shown includes an oil gun 1, a central air pipe 2, a gas pipe 3, a coal air pipe 4, and an axial flow air pipe 5 arranged from the inside out. A gas passage is formed between the pipe 3 and the central air pipe 2;
[0026] The gas channel is provided with a swirling wind regulating mechanism 6, which includes a number of swirling wind regulating fan plates 607 evenly installed on the outer periphery of the central air pipe 2, and the swirling wind regulating fan plates 607 are processed into a T-shaped structure. The plate 607 is installed on the outer periphery of the central air duct 2 through the set screw 606, and the set screw 606 passes through the middle part of the swirling wind adjusting fan plate 607 to install the swirling air adjusting fan plate 607 on the central air duct 2, and the swirling air adjusting fan plate 607 can be wound around The positioning screw 606 swings, and th...
