前言强制循环热水锅炉发生突然停电后水的循环中止,但炉膛内仍有未燃尽的燃料在燃烧和放热,这时,锅炉炉管内水流可能停滞、倒流或微上升流动,有可能使传热恶化,引起超温爆管。为此,上海工业锅炉研究所委托我们进行此项试验,与北京锅炉厂协作,提供设计资料。有关停泄及上升流动时炉管传热特性的研究结果,已发表在《工业锅炉》(1985.2)上,题为《热水锅炉炉管的传热特性(上升流动及停滞)》,读者可参阅上述文献。本项研究是
Introduction forced circulation of hot water boiler after a sudden power outage after the suspension of water, but the furnace still unburnt fuel burning and exothermic, then the boiler tube flow may stagnate, backflow or slight upward flow, it is possible to make Heat deterioration, causing over-temperature burst tube. To this end, Shanghai Institute of Industrial Boiler commissioned us to carry out this experiment, and Beijing Boiler Works collaborate to provide design information. The results of a study on the heat transfer characteristics of furnace tubes during stop-off and ascending flows have been published in “Industrial Boilers” (1985.2), entitled “Heat Transfer Characteristics (Upflow and Stagnation) of Hot-Water Boiler Tubes” See the above document. This study is
