What parameters do I need to provide for steam radiator design?

Firstly the following parameters are required for steam radiator selection.

   1. Fan air volume? (m3/h)

   2、Steam pressure (MPa) and temperature (℃)?

   3、Air inlet temperature? (℃)

   4、Outlet air temperature (℃)

After providing the above parameters, our designer will help to calculate the selection of the model.

Heat required to heat air Q=GCp(t2-t1) where  

      Q-Heat, KW

      Cp-air specific heat, Cp=1.01kj/kg*℃

      G- volume of air to be heated, kg/s, i.e. air volume

      t1-inlet air inlet temperature °C

t2-Outlet air temperature °C

Steam radiator supply heat Q' = KF ∆T

       K - heat transfer coefficient of the steam radiator, W/㎡*K

       F - heat transfer area of steam radiator, m²

       ∆t - average temperature difference between the remaining air of the heat medium, K

When the heat medium is hot water ∆t=(Tw1+Tw2)/2-(t1+t2)/2.

When the heat medium is steam ∆t=Tg-(t1+t2)/2.

Tw1, Tw2 for the initial and final temperature of the hot water ℃, Tg for the steam temperature ℃, pressure below 30kPa when Tg = 100 ℃, pressure above 30kPa Tg equal to the saturation temperature of steam at that pressure.
