Burn barrel ventilation holes

I've been using an old 45 gal. diesel drum to burn leaves and branches,
and, maybe because of our excellent summer, am finding it more
difficult than expected to get everything to burn.
I had made a series of small holes (about 5/16) in the base, and a
similar series in two rings around the lower part of the barrel.
Enlarging three of the lower holes on the barrel to one inch didn't
seem to help the burning.
Does anyone have recommendations for optimum ventilation?

Standard technique is to whack in some 1" holes using a pickaxe.

If you cut 1/3rd of the top and 1/3rd of the bottom off a steel drum,
then similarly whack in the holes they make a superb barbeque when set
on a suitable frame, using weld mesh as the grilling surface. I've
three done this way, and an angle iron frame to sit them on that
neatly gets lifted to where ever we are feeding using forks on the
back of the tractor. Last used a few weeks ago when we fed a couple of
hundred people over two days.

That's interesting, thanks for that.
The two rows of ventilation holes were to try to get it to act as a
gasifier, with a primary and secondary air supply. This burns much
more efficiently and cleanly than a simple fire for lots of reasons
that can be found on the internet.

ventilation holes as specified (pick-axe). I set up a blower with an
old cylinder vacuum cleaner; the hose on some of these could be
connected to the outlet if you needed a blower. Air was blown into the
bottom of the barrel through a 10' length of scaffold tube, so the
vacuum cleaner didn't get hot.
After getting it burning, I set the vacuum cleaner going. Burning
became very intense, all smoking ceased; 5 or 10 minutes later the
barrel was incandescent, literally red (bright) hot. It started to
collapse under it's own weight. Predictable; I'd made a blast furnace.
A small blower would do this very well; a fan from a dead boiler or
a car blower would do nicely. The latter would have speed controls.

Stuff burned but it smoked a lot, the ventilation gradually blocked
with ashes and is smoked more, so I tried super-charging it, as
described.

Hehe.
I had best results by entering the air pipe tangentially - the
incoming air cools the wall of the barrel as it spirals around.
I got this idea from building a Turk burner for consuming old chip
oil.

I'll have to see if I have anything which would do the job, though
maybe just enlarging the holes would help. Your suggestion has brought
to mind a memory from _many_ decades ago, of how effective small bellows
were at resuscitating a fire from one or two embers.

That's a very useful link; some concrete suggestions about hole size
and spacing, though garden waste is a bit different from "containers".
I didn't want to start with large holes then try to reduce them!

I was hoping to reduce the mess by leaving the bottom in place and just
perforating it a bit.
I'll see how larger holes in the sides works out.
I was actually surprised that it didn't burn better, but probably the
fire was being starved of oxygen.

Think I'll try enlarging the side holes first; I'm trying to keep the
assorted small unburnt (green) twigs etc. inside for easy removal.
Of course if I got it to burn well enough, even the green stuff should
be reduced to ash.

Branches on the bushes above are due to be lopped off anyway. Very

Their great advantage is that they're stainless, so they're allowed to
be visible and don't have to be hidden away all the time....
An incinerator needs draught and this ought to be natural draught, not
faffing about with a fan. So that means height. Barrels good, washing
machine dums too short. A washing machine also has holes in the side,
not in the base, so the draught is top air and largely robbing any
useful draught you might get, in favour of just being a convector
heater. The side holes are also on the small side, so there isn't
really enough air through them.
So for both barrels, your main air supply needs to be pickaxe holes in
the base, or at least the bottom of the sides below a mesh burn
platform. With a washing machine drum, this is enough for burning
with secondary air for a clean burn through the side walls. More
height wouldn't hurt though, so if you can get a second WM drum, cut
the base and stack that on top (twisted fence wire loops will hold
them together).
If you're lucky, the drum spider can be used as a support to raise
them off the ground. Mine's welded to a bit of old pipe and spiked in.

IMHO, they're a good start but they need work and aren't perfect.

Natural gas is a sight easier to burn than wet biomass and most of us expect

to have fans in boilers. Fans provide turbulence, one of the 3Ts needed for
good combustion.
Have a look at air curtain burners, one way of burning tonnes of waste wood
fast, I have built several, including using a 45 gallon drum and an Earlex
vacuum with thyristor speed control.

I make a lot of use of mine for garden clearance and certainly hope they
are never banned. It is essential to get good air flow and a hot burn
otherwise there is a lot of smoke. I have been tempted to run a couple
of lengths of 20mm steel electrical conduit into the bottom of the
barrel and pump air through to liven it up a bit. The idea of raising
the material up on a mesh is interesting, must remember to blag some
stainless mesh off my dad next time I visit.
