May I ask if the flue gas pipes of the heating furnace can be routed through a ductwork system for long-distance transmission?

SeaFriend’s question: Can the flue gas pipes of the heating furnace be routed through a pipe tray for long-distance transmission?
No. Reason: 1. The pipeline is too long, resulting in high resistance and affecting the negative pressure of the heating furnace ； 2. The power of the exhaust fan needs to be increased ； 3. High energy loss.
Previously, the fuel for our heating furnace was natural gas; the flue gas passed through the steam generator and then went straight up the chimney via the exhaust fan, haha
What is the purpose of the original poster wanting to do this?
I guess it’s to use the heat energy from the smoke for heating
For long-distance transportation, the cost of thermal insulation materials alone is sufficient to cover the savings achieved through the utilization of waste heat.
What I’m actually more curious about is whether, from a regulatory perspective, it is allowed for the flue pipes of heating furnaces to be placed in utility tunnels and transported over long distances.
It took you a long time to show up; actually, everyone is asking why your smoke needs to be transported over long distances – what’s the purpose of that?
Our company’s management, in pursuit of aesthetics, wants to have all the chimneys placed together for centralized exhaust. This approach is not only uneconomical but also hinders the operation of the heating furnaces. However, they won’t listen to any other arguments, so I was wondering if anyone has any persuasive standards or guidelines: Q
Make an estimate for the investment. Does the smoke need to be cooled before being sent through the pipes? When transporting smoke over long distances, does this increase the load on the ventilation equipment? Is it necessary to use exhaust fans? There are also issues related to corrosion protection of the smoke pipes. Everything can be done if there’s money; don’t end up in a poor situation due to lack of funds
