Now the rest of the story… So you can see that the condensate was being led to pool right into the area surrounding the burn chamber. I am not able to say if any moisture got into the char bed, but the next day, it rained so the humidity was high. Anyways, after about 48 hrs, I went to start up the unit with all that nice char, and could not even get it to make a flare that would stay lit. Yes, I added new fuel and all, and the char got up to about 1,300 degrees, but I could tell that it was packed up.
When I checked the drip line on the filter train, It was pulling 7-8 inches of water, and it typically pulls 2-3 or less.
So the next day I cleaned out the chamber and saw that it looked similar to the photo above at the top, but was REALLY packed with lots of tiny pieces (almost like sand in size) rather than whole pellet pieces or really light ash. I have not burned much wood except in a fireplace and fire pit, but this pellet char seems to act differently than the natural wood char I use in my BBQ smoker…
So any ideas if this breakdown of pellet char is due to absorption of moisture (either from the environment or from the condensate routing) ?
Could it be from the pellets just sitting there hot for a while as the gasifier slowly cools down ?
