【摘要】 本文对列管式废热锅炉火管管间液体流速场和温度场进行了实验研究.采用W1269型水热膜探头和1050型热膜风速仪测定了流场速度分布,用铠装热电偶测量了工质温度分布,并就出水口位置的影响进行了研究,根据实验结果对流场进行了分析,解释了实际应用中上管板经常变形和泄漏等事故的起因.更多还原

【Abstract】 The velocity and temperature profiles of water flow in the shell-side of a shell-tube waste heat boiler were experimentally studied. The influences of some factors on the flow and heat transfer characteristics were investigated. Some further analyses and discussion on the flow field were made, and some operating problems were explained. The test system and measuring method are described in detail.更多还原
