(一)日本中外炉公司研究的热风比调烧嘴。可用500℃热风烧重油。其特点是:用于高温加热炉,在平均预热空气为400℃时,因回收利用了废热,可以节能31%。其低过剩空气燃烧效果也比较好。油的物雾化用低压助燃空气(500~800nnH_2O),不需高压雾化蒸气和压缩空气。用一个手柄操作。整个出力范围空气比保
(A) Japan and foreign furnace companies to study the hot air ratio burner. Available 500 ℃ hot air burning heavy oil. Its characteristics are: for high temperature furnace, the average preheated air at 400 ℃, due to the recycling of waste heat, you can save 31%. Its low excess air combustion is also better. Oil material atomization with low-pressure combustion air (500 ~ 800nnH2O), without high pressure atomized steam and compressed air. Operate with one handle. The entire output range of air than Paul
