淺析蒸汽散熱器的基本加熱過程有哪些?

發布時間:2021-12-02  點擊次數:2984 次
       蒸汽散熱器主要對氣體流進行加熱的電加熱設備,它的發熱元件為不銹鋼(不銹耐酸鋼)電加熱管,設備內腔設有多個折流板(導流板),引導氣體流向,增加氣體在內腔的滯留時間,從而使氣體充分加熱,使氣體加熱均勻,上升熱交換效率。
       蒸汽散熱器的加熱元件不銹鋼加熱管,是在無縫鋼管內裝入電熱絲(類別:鐵鉻鋁合金絲、鎳鉻合金絲),空隙部分填滿有良好導熱性和斷緣性的氧化鎂(化學式Mg)粉后縮管而成的。當電流通過高溫電阻絲的時候,產生的熱通過結晶氧化鎂粉向加熱管表面擴散,再傳遞到被加熱空氣中去,以符合加熱的目的。
