      摘要: 這是一個儲罐蒸汽加熱盤管的在線計算程序,可計算加熱面積和盤管長度
      儲罐在線計算程序可計算大罐蒸汽盤管的面積和長度This program can calculate the area & length required for an internal coil carrying condensing steam for heating the tank contents

      數據輸入Data

      批次質量Mass of Batch (M) lb
      初始溫度Initial Temperature (t1) °F
      最終溫度Final Temperature  (t2) °F
      蒸汽溫度Steam Temperature (T1) °F
      比熱Specific Heat (Cm) BTU/lb.°F
      總傳熱系數(Overall H.T.C.) (U) BTU/h.ft2.°F
      加熱時間Heating Time (θ) hr

      計算結果Solution

      若使用恒溫加熱介質通過內部盤管來加熱一個批次,可使用以下公式:(For heating a batch with an internal coil with an isothermal heating medium, following equation is applied:)

      面積Area (A) = ((M.Cm)/(U.θ))* ln((T1 - t1)/(T1 - t2))

      面積Area (A)  = 32.59ft2

      加熱盤管配置Heating Coil Details

      盤管外徑Coil OD = inch

      盤管長度Coil Length (l) = Area/ (3.142 *OD)

       = 62.23ft

      計算中是否考慮油罐散熱?
