近年来,平焰烧嘴在工业炉中广泛地得到了使用。国内外大量实践证明,用平焰烧嘴改造加热炉,特别是室式加热炉,具有升温快、节约燃料、炉温均匀等优点。这是由于平焰烧嘴以辐射传热方式为主,有均匀的温度场,向被加工件直接地定向地传热,而强化了炉膛内的热交换的结果。平焰烧嘴在国内已有多种类型,各地都取得了不少经验,正在形成平焰烧嘴系列,但必须注意到,选用平焰烧嘴改造旧加热炉虽简单易行,但对原有炉型和设计参数应适当地处理和修改,否则,得不到较好的节能效果,现就采用发生炉煤气平焰烧嘴改造室式加热炉的几
In recent years, flat-flame burners have been widely used in industrial furnaces. A large number of domestic and foreign practices have proved that the flat flame burner to transform furnaces, especially room-type furnace, with fast heating, fuel savings, uniform furnace temperature and so on. This is due to the flat flame burner radiant heat transfer is the main way, there is a uniform temperature field, the workpiece is directly directed heat transfer, and enhanced heat exchange within the furnace results. Flat flame burner has many types in the country, has made a lot of experience around the flat flame burner is forming a series, but it must be noted that the selection of flat flame burner to transform the old furnace is easy, but the original Furnace and design parameters should be properly handled and modified, otherwise, can not get a better energy saving effect, now on the use of gas furnace flat flame burner chamber furnace transformation of a few
