高速烧嘴是一种大功率燃气装置,能产生强大高温气流。高速烧嘴的基本原理是,燃料在燃烧室或燃烧坑道前半部基本实现完全燃烧。由于燃烧室是密封的并保持足够高的压力,使高温的燃烧气体以高速度(100～300m/s)由烧嘴口喷出。因燃烧的气流喷出速度高,从而强化了对流传导,保证了炉温的均匀性,能实现快速加热并减少工件的氧化脱碳,提高工业炉的生产率。
High-speed burner is a high-power gas appliances, can produce a strong high-temperature airflow. The basic principle of a high-speed burner is that the fuel basically burns completely in the combustion chamber or the first half of the combustion tunnel. Since the combustion chamber is sealed and maintained at a sufficiently high pressure, the high-temperature combustion gas is ejected from the burner port at a high speed (100 to 300 m / s). Due to the high jet velocity of the combustion air flow, convection conduction is strengthened, the uniformity of the furnace temperature is ensured, the rapid heating and the oxidative decarburization of the workpiece are reduced, and the productivity of the industrial furnace is improved.
