爐熱損失試驗
英文
oven loss test-
After thermodynamic calculation on several operation conditions of the furnace, cold - state flow and resistance mensuration, the combustion of the tubular - furnace hearth was changed into swirl and addition of radiate cylinder and oxygen content detection minish 1. 25 surplus air to less than 1. 15, improving the combustion condition and convection and radiate heat transfer efficacy, resuling in reducing the waste - gas temperature 45, decreasing exhaust gas loss, and saving fuel by 6 %
摘要通過對加熱爐幾種工況進行熱力計算、冷態試驗的流場分佈及阻力測定和熱態試驗的爐膛溫度場分佈及管壁溫度等參數的測定,確定將管式加熱爐爐膛內直流燃燒改為旋流場燃燒和增加輻射筒,增設煙氣含氧量分析,可以將燃燒的過剩空氣系數從1 . 35減小到1 . 15以下,極好地改善爐膛內的燃燒狀況和對流輻射傳熱效果,從而降低排煙溫度45 ,減少加熱爐排煙損失,節約了煤氣量6 %以上。This paper has analyzed and synthesized the problems of burning heavy viscosity petroleum about injecting steam boilers in liaohe oil field. the heat balance experiments on injecting steam boilers burning heavy viscosity petroleum is made first. the main causes of low thermal efficiency and heat lose of flue gas are the poor effect of atomization and burning with old - fashioned oil nozzles, worse ash gathered on. heat exchange surface and high temperature of flue gas
本論文在分析綜述了遼河油田注汽鍋爐燃用高粘度稠油時存在的問題的基礎上,首先對燃用稠油的注汽鍋爐進行了正、反熱平衡試驗,分析了注汽爐熱效率偏低、排煙熱損失偏高的主要原因是原噴油嘴改燒高粘度稠油時霧化和燃燒效果差、換熱面積灰嚴重、排煙溫度太高。
