一、前言自身预热烧嘴是近十年来发展起来的一种高效节能消烟烧嘴。该烧嘴于七十年代中期,首先由英国研制成功。联邦德国、美国也有同类产品。由于其节能效果显著,经济效益突出,应用范围不断扩大。主要用于加热、熔化、热处理及间歇式窑炉等各种工业窑炉。为解决我国工业窑炉的节能及环保问题,航空部四院于1979年开始研制自身预热烧嘴。采用了旋流雾化,气流附面冷却,流量自动补偿,高速喷射等新技术。使烧嘴的冷态雾化粒径、适用燃料范围、空气预热温度、节能效果等 First, the foreword Preheating the burner itself is a highly efficient energy-saving smoke burner developed in the past decade. The burner in the mid-seventies, first developed by the United Kingdom. Federal Germany, the United States also have similar products. Because of its significant energy-saving effect, prominent economic benefits, expanding the scope of application. Mainly used for heating, melting, heat treatment and batch furnaces and other industrial furnaces. In order to solve the problem of energy saving and environmental protection in China’s industrial kilns, the four homes of the Ministry of Aviation started to develop their own preheating burners in 1979. The use of cyclone atomization, airflow cooling, automatic flow compensation, high-speed jet and other new technologies. So that the burner atomization of the cold particle size, the scope of the fuel, air preheat temperature, energy-saving effect
