I would like to ask how to simulate the waste heat recovery system of a heating furnace?
Thread Content
I want to simulate a waste heat recovery system, including thermal balance, energy calculation, heat transfer calculations for the equipment, and smoke and air resistance calculations. It relates to the selection of fans, as well as issues such as the pressure drop across various waste heat recovery devices. I would appreciate your advice on this
This is a major issue; first of all, thermal equilibrium and energy calculations need to be addressed； Then comes the equipment heat exchange calculation, followed by the smoke and air resistance calculation ； It’s likely that a single software program won’t be enough to solve this problem.
It is possible to simulate the entire system. But as for the waste heat recovery system you mentioned, I haven’t worked with it before; I’m looking forward to hearing from experts.
Proii can only perform thermal calculations; the selection of fan equipment should be provided by the manufacturer, heat exchangers are calculated by HTRI, and pipe resistance is calculated by inplant. Detailed equipment simulation is required; Fluent can be used for this.
Thank you, sir. It seems there’s still a lot to learn. In that case, I’ll have to use Pro for the thermal balance calculations first. However, generally, manufacturers need to be provided with data such as air volume and pressure drop; this is actually related to the pipe resistance throughout the entire system. I’ve never done inplant work; before, I would just estimate the resistance
That’s right; if you don’t mind, you can send me the requirements and the process, and I can provide some guidance. We are a compressor manufacturer. happy031@163.com
It’s not as exaggerated as what was said above; if you’re skilled enough, software like Aspen is generally sufficient for the task. Of course, for heat exchange calculations, HTRI is more reliable
