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
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.
