Internal Heating Coil Design
Internal Heating Coil Design
(OP)
Hi,
We are going to design a vessel with a coil and I am not very familiar to design of heating / cooling coil. How may I find a reference to design of heating or cooling coil. Our problem now is that we need to find the height of the coil and to determine the length of the coil as well.

-flow rate to obtain diameter of coil
-internal pressure/temp and material to obtain thickness of coil
-surface area for obtain length and height
RE: Internal Heating Coil Design
from a book I refered to states that the pitch between the two diameter equals to 1.5*outside diameter, and the outside diameter spacing equals to 0.5*outside diameter.
So based on those two formulas, let say I have 7 no. of turns, so it would be:
(1.5*outside diameter)*6 + (0.5*outside diameter)*6
is this calculation valid to determine the height of the coil?

There is simply too much to tell to be of much use at the moment - you can come back to this forum when you have gone through chapters on forced and natural convection.
Pressure drop can influence the design of this coil also.

For internal hi, there are correlations available in Perry for coils.
Most likely, ho will control the value for U if this is clean service inside and outside.
