How To Feed The Fire - Air Burners T-400 Operating Manual

It will generally take 30 to 60 minutes for the fire to build to a point where the tempera-
tures are sufficient for the unit to be operating with minimal smoke.
1.
Add material from your "Good Wood" pile slowly for the first hour. It takes about an hour
for the fire to reach minimum temperature. Your goal is to achieve an even and hot fire
across the unit.
2. If you get excessive smoke and ash when you load the wood waste while dropping the
load through the air curtain, then you may need to turn the RPM's down temporarily as
you load.
3. Take caution when loading the pit that the material to be burned is not "dumped" in the pit
too quickly causing hot embers to be thrown from the unit.
4. If you have an area in the pit that is smoking, this indicates the temperature is low in that
area. Add material from the "Good Wood" pile to get the fire temperature up. Once that
area is burning add some of the heavier material.
5. The rate at which you load the pit varies depending on moisture content of the materials
and the temperature of the fire. If you overload the pit you will notice an increase in white
smoke. White smoke is an indication that the temperature is dropping. If the smoke in-
creases stop loading until the fire has caught-up. You can also bring the temperature up
by adding materials from the "Good Wood" pile.
6. For the highest throughput load "LESS MORE OFTEN." Smaller bucket loads more often
will give the materials a better chance to burn and will result in your highest throughput of
material. Oversized bucket loads may smother the fire for a short period before it ignites;
this will slow the burning down and reduce your daily throughput.
7. The load in the pit should not go higher than 1 foot below the manifold. If the material is
piled higher it will begin to break the air curtain and more smoke will escape.
8. The fire should be loaded continuously throughout the day in order to maintain op-
erating temperatures. If the fire is not loaded continuously, the temperature will
drop, the through-put will go down and more smoke will escape.
"If it's burning clean, it's burning fast, If there is smoke, you're losing money."
