The high-speed burner is that the fuel and the combustion-supporting air are basically completely burned in the combustion chamber, and the high-temperature gas after combustion is ejected at a speed of 100m-150m/s, so as to strengthen the convective heat transfer, promote the airflow circulation in the furnace, and achieve a uniform furnace temperature. The purpose is to make the heat preservation uniform at ≤±10℃.The Function And The Production Of Ceramic Bulletproof Vest the burner a, the combustion chamber volume is small b.
