Natural cooling heat exchange

Flue gas with a flow rate of 1700 cubic meters per hour and a temperature of 500 degrees flows inside a steel pipe with an outer diameter of 400 mm; the pipe is exposed to air (which means it cools naturally). Now, it is necessary to calculate how long such a pipe needs to be in order for the 500-degree flue gas to cool down to room temperature

I was wondering, has this problem been resolved after 3 years? I have the same problem

This natural convection heat transfer coefficient is very low; is it really worthwhile to use 400mm pipes?
