Steam preheater
Thread Content
Use steam at 170 degrees to heat a room measuring 12 meters in length, 4.7 meters in width, and 2.5 meters in height to 80 degrees. Determine the external dimensions and heat exchange area of the preheater. Thank you
Is the poster trying to use that type of coil to heat the air in the room? It works on a principle similar to that of HVAC systems, I guess. But this heating temperature seems a bit high.
It can be used to roast people, right? Hehe
The client requires a temperature of over 80 degrees; it’s a sealed room with hot air circulation. Can steam at 170 degrees maintain a temperature of at least 80 degrees? :P

But you have overlooked a few key figures: heating time. If there’s no time, then there’s hardly any need to calculate ； Wall material: Wall thickness: Name of the insulation material outside the wall: Thickness of the insulation material outside the wall: If it’s just a casual question, I don’t need to go to any trouble; but if it needs to be taken seriously, the calculations are quite complex. If it is an engineering issue, it needs to be taken seriously.
