Chimney cross section selection in central heating
Chimney cross section selection in central heating
(OP)
Hello to all,
I am trying to find required chimney cross section for a 47kW power central heating system.
I have used until know the following equations:
from DIN 4705
Redtenbacher that gives me a 0.037 square metres
Another one is Plewa and it gives me 0.03 square metres
and a last one from greek standrards organisation and from DIN 0.02 square metres. And also in Greek literature it is noted that DIN 4705 can be used. But German standards give me 0.037 and 0.02, but greek 0.02
Can someone please help me where to find the best way to calculate the cross section of a chimney?
I would really appreciate any thoughts and ideas.
Thank you in advance,
Poseilus.

Where can I find the International Mechanical Code? Or the power plant engineering textbook?
