How to calculate Boiler Stack Height for HR
How to calculate Boiler Stack Height for HR
(OP)
Hello, i came across this topic and can't seem to find an answer. The boiler that is being used is a Horizontal Return Boiler with a Combustion Firebox in front of the boiler, the boiler HP is 100BHP. The solid fuel is regular pine. It is set at an open field with no restrictions. I am located at 1000m above sea level. I want to use natural draft from the stack height. Anyone know a good aproximation for the stack height.
Boiler has 3" diameter tubes.
20" diameter stack.
Thanks
