Discussion Overview

The discussion revolves around the modeling of an electric superheater, specifically focusing on the calculation of the overall heat transfer coefficient. Participants are exploring whether to use radiant or convective heat transfer calculations, with considerations for different types of superheaters and flow conditions.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the appropriate calculation method for the overall heat transfer coefficient, questioning whether radiant or convective methods should be used.
  • Another participant asks for clarification on the type of superheater and the method of transferring electric energy to the vapor phase, as well as whether the system is for batch or continuous flow.
  • A participant mentions using tubular heating elements for heat transfer and specifies that the flow is continuous, indicating a focus on a particular design choice.
  • There is a suggestion that the modeling may be a continuation of previous work related to a boiler and steam evaporator.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the method for calculating the overall heat transfer coefficient, and multiple viewpoints regarding the type of superheater and flow conditions are present.

Contextual Notes

Participants have not provided specific details on the assumptions or definitions related to the heat transfer methods, nor have they resolved the mathematical steps involved in the modeling process.

Hello everyone,
I am dynamically modelling a electric superheater. During the calculation I need to calculate the overall heat transfer coefficient. Can someone tell me which calculation do I need to use to calculate the overall heat transfer coefficient, radiant or convective?
Please clear my mind.
With regards

Hello again,

What kind of superheater ? How do you intend to transfer the electric energy to the vapour phase ?

And remind us whether this was for batch or for continuous flow.

sorry for the link, i have deleted it and will upload the clear view of the boiler
Is this the same project ? I haven't found your clear view yet ...
 
Hello all,
I am planning to use a tubular heating elements for heat transfer, unlike the readily available electric superheaters now. I am not concerned about the physical design parameters. The flow is continuous.
with regards
 
I suspect Vishnu is only modelling ...
 
Hello all,
something like an extension of my previous work on boiler and an single effect steam evaporator has been added and the steam generated has to be superheated.
