針對早期建造的煉油廠和化工廠在役管式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，增大對流管表面積以增大對流段的熱負荷；增加輻射管的換熱面積；修正煙囪高度；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，減小過剩空氣系數，節省燃料2 % 3 % ；在對流段和煙囪之間增設空氣預熱器以提高空氣入爐溫度；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。The bigger the diameter, the high the heat efficiency, but the weak the temperature increasing ability, length has less effect on the heat efficiency, tilt angle has less effect on the flow field and temperature field while it is larger than 30 degree, vacuum degree and emissivity have great effect on the flow field and temperature field while there is a great temperature difference between the liquid in the tube and the surroundings, the furring has less effect on the heat transfer but should be cleaned up in 3 - 5 years because of poor water quality, the higher the solar flux or the more the temperature difference between the liquid and the surrounding, the more the heat loss and the lower the heat efficiency
分析了各種因素對太陽能真空集熱管流場和溫度場的影響。直徑越大，熱效率越高，但升溫能力弱；長度對熱效率影響不大；傾斜角度大於30后，自然對流已經能夠充分進行，考慮以能夠吸收到最大太陽輻射為主；真空度和發射率對熱效率和溫度場影響很大，尤其是在介質溫度與環境溫度差異比較大時；水垢對傳熱影響較小但由於水質的問題應該被3 5年清洗一次；太陽輻射強度越大，介質溫度與環境溫度差異越大，熱損失越大，效率越低； 4Single burner gas fired overhead radiant tube heaters and non - domestic gas - fired overhead luminous radiant heaters. requirements and test methods for establishing the rational use of energy. radiometric method a
