This coal was the easiest to start out of all the coal I've tested so far. It was lit and burning within a minute or so. It produces very little ash, but more than the Wyoming coal. After burning about 45 pounds, the ash was still on the ring and hadn't fallen into the ash can. There were no clinkers formed and the fire was very hot.
There was no problem feeding the coal, which was sized properly.
Tried different settings on the air. A setting of 3 produced a full pot of burning coal, but was too smokey. A setting of 4 was acceptable, but still produced a little smoke in the boiler. A setting of 5 produced a clean flame with a little burning down into the pot. It also produced intense heat, with flames shooting up to the top of the boiler. Holds the fire well during the downtimes and checking the overnight hold now.
After playing around with the settings, the final air setting was 5 and the feed was maximum. There was a careful balance of air to feed ratio so the coal wouldn't burn down into the pot, but yet burn as smoke-free as possible. The videos show the fire and smoke with these settings.http://www.youtube.com/watch?v=qtaQWfDwnbohttp://www.youtube.com/watch?v=Y00uNSylX7I
