Why are chimneys located at the front

[eddiej]

Whilst trying to decide upon which design of construction to use, one common theme with WFO construction seems to be the chimney location.
Is there a practical reason for locating the chimney towards the front?

For my chosen site location, I would prefer to use the rear.

The air enters low and fuels the combustion, the fire is hot and the gases rise and exit over the incoming cooler air.

This gives positive benefits in cooking.

If you want the chimney at the back take the exiting gases and bend the chimney to the rear. It probably isn't the most efficient and you may experience problems with the exhaust gasses exiting through the entrance.

If you have a tall chimney and a good draw it may work well when up to temperature.

Why do you prefer the rear?

I have seen some ovens in Napoli with a double cavity roof with the chimney at the back, they seem very stable with hot gasses above the dome. this system is also used in the "pizza party" mobile oven. one had a heat exchanger in the cavity running a hot water supply from the WFO..

Thanks for the replies.

Because of how I had planned the layout in my head in relation to location I had thought that a rear chimney could work better. After laying in bed last night thinking it over again, I can infact see several bonuses for having it at that front, so that is now one decision laid to rest.
