Chimney Design

You need to have more inputs like your location,windspeed in your location,soilconditions of your location,composition of your boiler exhaust with special focus on sox, temperature of exhaust etc then refaer any strctural design book for design of chimney.

best of luck

In addition, he better check all applicable codes and regulations if he doesn't want to have to tear it down after he builds it.

Things to consider: 1) Smoke stacks must be constructed according to codes because insurance companies require it. 2) Use prefabricated double wall stainless-steel stacks, otherwise fabricating a stack and insulating it is not really cost effective, until you get into large boilers requiring breeching, etc. 3) Unless boilers are fired simulaneously, use separate stacks, otherwise you may not have enough draft to carry out the products of combustion without condensation taking place in the stack. 4) The manufacturer of the boilers can give you the required size of the stack(s). 5) Stack must be minimum of 2 feet above the roof.

Hope this helps.......

I don't mean to be discouraging but if you need to ask these questions don't attempt this project. There's a lot more to flues than meets the eye!

Two sources to one chimney?!

I have seen the effect in one "experimental oil refinery".

After the second source started, the chimney became an outer space rocket driven by exploded gases+dust

It became a "civil engineers' joke" for the observers
