摘　　要：通过在焦油装置管式炉对流段增加一段焦油管,对燃烧器进行改造,利用高温烟气余热预热助燃空气,降低了烟气排放温度;在管式炉煤气燃烧器对流段增加11根炉管提高了管式炉的热效率,煤气耗量明显降低,由改造前的883 m3/h降到729 m3/h,降低了装置的能源消耗。废气排放温度从原先的364℃下降到204℃,明显减小了废气带走的热量。煤气燃烧完全,废气含氧量从原先的高于10%下降至4.8%,管式炉热效率明显升高,由原先的76.4%升高到85.0%。A section of tar tube is added in the tar device tube furnace to modify the burne, the high temperature flue gas waste heat is used to preheat the combustion-supporting air, and the flue gas emission temperature is reduced. By increasing 11 furnace tubes in the tube furnace gas burner convection section,the thermal efficiency of tube furnace is improved, and the gas consumption is decreased obviously, by the transformation before 883 m3/h to 729 m3/h, the energy consumption of unit is reduced. The exhaust temperature decreases from 364 ℃ to 204 ℃. The gas combusts completely, the oxygen content of flue gas changes from above 10% to 4.8%, tube furnace thermal efficiency rises, which increases from the original76.4% to 85.0%.
