圓錐形噴嘴水頭損失的計算公式與試驗研究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。The results show that the improved structure has obviously reduced pressure drop and increased axial speed of the nozzle, as a result the wallop of electroplating solution is improved and the thickness of diffused layer reduced, the electrodeposition process improved, and what is more, the coating structure has been compacted, crystalline particles fined and the performance improved
結果表明,結構改進后,明顯減小了壓力損失,提高了噴嘴的抽向速度,電鍍液沖擊鍍件的沖擊力得到提高,有效地減少了擴散層的厚度,改善了電沉積過程,而且使鍍層組織緻密,晶粒細化性能得到提高。
