  1. Abstract : the in servie tubular heaters built early in refineries and chemical plans have low thermal load and low heat efficiency, therefore measures for technical reform are offered, including ( 1 ) enlarging the surface area of convection tubes to increase the thermal load of rhe convection section ; ( 2 ) increasign the heat interchanging area of radiant tubes ; ( 3 ) changing the height of the chimney ; ( 4 ) using new burner with forced air supply to increase calorific capacityu ; ( 5 ) adding air preheater between the convection section and chimney to enhence the temperature of the air entering the furnace ; ( 6 ) adopting high temperature radiant coating to improve the effect of radiant heat interchanging

    文摘:針對早期建造的煉油廠和化工廠在役管加熱爐熱負荷和熱效率低的狀況,提出了若干技術改造措施包括,增大對管表面積以增大對段的熱負荷;增加輻射管的換熱面積;修正高度;換用新型燃燒器,變自然通風為強制供風,以增大燃燒器的發熱量,減小過剩空系數,節省燃料2 % 3 % ;在對段和之間增設空預熱器以提高空入爐溫度;採用高溫輻射塗料增強輻射換熱效果,從而增加熱源對爐壁的輻射傳熱量和爐管的傳熱量等。
