Crater structure:
The use of off-type shell crater structure, two burner body by bolts, constitute the entire crater cavity, crater lower body rotation with mixed gas heating device, the upper body with spiral steady flow and nozzle components. To gas mixture by preheating the input pipe by first mixing chamber into the crater, and then cut to two rows of holes through the mixture into the second mixing chamber, then through the screw steady flow, T-diamond-shaped nozzle into the combustion chamber. By the second mixed-pressure steady flow, the increase of the gas mixture temperature, the gas to speed up the process of energy exchange, so that, once ignited, the flame will be sprayed through the slit-type jet fabric, to achieve high-quality singeing purposes.
The crater using STSi5 material manufacturing, solid temperature, with cooling water on both sides of crater upper body, can by-pass water cooling to prevent heat deformation of the crater, with four AM board; Can effectively adjust the flame temperature, to adapt to different widths products singeing.
Three kinds of burning cloth ways:
Of burn, burn through, cut burn; For different fabrics and different process requirements to select a different way of burning cloth in order to achieve the desired effect of burning cloth. (Photos)
