Tractor exhaust extraction

[jamesmerriman7]

Hi guys advise needed!

put up a new shed to process firewood. Got a pto processor ran off an old tractor and need to extract fumes. Any firms you recommend or ideas about simple extraction.... cheers

Stick a long flexible pipe on it and run it outside, cheaper than fitting extraction and more effective as well.

Wonder if you could improve on that idea with a bathroom extractor fan and length of flexi hose?

Already tried a flue liner burnt through on the bends

On construction site we sometimes use a scaffold tube to vent exhausts away from a work area.

It's got to travel 10 meters would I need a fan or would fumes find its way out the pipe

If you put a fan bringing air into the workshop the pressure will force any fumes out. This is the method used for paint spray bays. Is the workshop 20 meters wide and the tractor in the middle ? The fumes would find their way out through a sealed pipe system such as a piece of flexy linked to say the scaffold pipe suggested earlier just knock a hole in the wall or take it to a window or door.

The tractor is in the middle of an 80ft by 80ft shed. The roof has vented ridges. So your saying a length of scaffold tube fitted over the exhaust with a reducer to take a 4-5 inch flexi pipe out? Been reading up on exhaust temperatures, 400/600 degrees under 60-80% pto load! Scaffold tube take that heat? The ridge gap at top of roof is only 75mm so hose would have to follow shed frame as you wouldn't want to reduce hose at the end. This is all new to me!!!

Make an adapter to a long slot exit pipe.

 

Double the cross sectional area of the pipe should do it.
