近年来,国内许多部门和单位研究开发了多种型式的新型煤粉燃烧器,并且在许多电站锅炉上推广应用,取得了成绩。我省燃烧福建无烟煤的锅炉上也曾应用或研制夹心风燃烧器、钝体燃烧器、中心火炬预燃室、大速差射流燃烧器和煤粉浓淡分流及分路燃烧装置等新型煤粉燃烧器。福建无烟煤的挥发份含量仅3～5%,且着火温度高,燃烧性能差,着火难、稳燃难和燃尽难,是最难烧的煤种之一。本文试将几种 In recent years, many domestic departments and units have researched and developed various types of new-type pulverized coal burners and have made achievements in many power plant boilers. Burning Fujian anthracite boiler has also been applied to the development or development of sandblasting burner, bluff body burner, the center of the torch pre-combustion chamber, a large difference jet flow burner and the pulverized coal shunt and split combustion devices such as new type of pulverized coal combustion Device. Fujian anthracite volatile content of only 3 to 5%, and the ignition temperature is high, the poor combustion performance, the fire is difficult to stabilize the fire and hard to burn, is one of the most difficult to burn coal. This article will try a few
