High-speed burner is a kind of rapid heat combustion device widely used in industrial kilns. Under normal circumstances, it has a combustion chamber itself, and the fuel and air are mixed to achieve complete combustion (> 85%) in the combustion chamber. The high temperature flue gas formed after combustion is sprayed out at high speed from the burner nozzle by the expansion pressure.

The basic principle of high-speed burners is similar to that of a simple jet engine. The fuel can be almost completely burned in the front half of the combustion chamber or channel because the sealed combustion chamber maintains sufficient pressure, allowing the hot fuel gas to be ejected at a speed of 100-300 m/s. This high-speed airflow promotes gas circulation within the furnace, enhances convective heat transfer, and improves temperature uniformity inside the furnace, achieving rapid heating of industrial kilns and reducing workpiece oxidation and damage, thus saving energy and improving production quality. If adjustable secondary air is supplied at the outlet of the combustion chamber or in the rear half of the combustion channel, it can regulate the temperature of the combustion gas flow, forming a high-speed temperature-regulating burner. Additionally, high-speed burners can improve their performance by adjusting excess air and fuel, and they can even use multiple fuels for combustion, demonstrating strong adaptability to different fuels.

● Discussion topic 1: Basic working principle of high-speed burner

Definition/Explanation: A high-speed burner is an industrial combustion device characterized by the mixing and burning of fuel and air in the combustion chamber, followed by the ejection of high-temperature flue gas at extremely high speeds (100-300 m/s).
