The humidity went off the scale yesterday, so I decided to run a 'dry' test. At 4:30 PM, I loaded my AMNPS with 3/4 lb. (full load) of oven dried Cooking pellets brand hickory pellets and lit it. It is now 9:30 AM (17 hours later) and the pellets are still burning. And the humidity is still maxxed out.

This is absolutely the longest burn I have ever had. I think there are three factors at play here. I think humidity retards burn speed. I also think oven drying the pellets has an effect. And last, I believe having the damper on the 6 inch exhaust stack wide open allows for plenty of air flow.

That's my story an' I'm stickin' to it.

Sounds about right..

From the National Weather Service forecast for Phoenix, AZ:

".FIRE WEATHER...
Sunday through Thursday...
Drier westerly flow aloft will push monsoon moisture into eastern AZ
with only a slight chance of afternoon thunderstorms over the higher
terrain of southern Gila County through Tuesday. Accordingly,
minimum humidities continue to decline as well. Overnight recovery
will be fair. Humidities trend upward Wednesday and Thursday and
storm chances return to the lower deserts of Arizona. Winds will
favor familiar diurnal patterns."

Note the mention of humidity, very big factor in fire behavior, big or small.
 
 
Jim....  You've got it.....  Humidity reduces the burn temperature of the pellets just like it does to a forest fire....   Also it reduces the available oxygen per unit volume..  cooling the burn.....
