I'm trying to get a handle on burning a secondary stove as cleanly as possible through all stages of the burn, and I welcome advice from PE owners, and those who run other non-cat stoves. We just put in an Alderlea T5 at my SIL's house. A couple nights ago I started a top-down fire with five splits and some Pine kindling. As the top splits started to catch, the plume got clean very quickly so I started cutting air. I tried to sustain the clean burn by not cutting it too fast, but the plume got a bit dirtier. I saw a couple of small water spots on the end of two splits but nothing I thought was a problem at all...no bubbling. The stove top slowly went 200..300..400 and the stack slowly moved to 350. I never saw appreciable secondary burning and the plume stayed somewhat smoky. Maybe I saw the clean plume early because not that much wood was involved yet, just the kindling. I think the plume may have eventually cleared up when the stove went over 500, but it got dark out and I couldn't see it anymore. Some questions I have are: --How do you start out your non-cat loads to burn as clean as possible? Do you need to maintain a certain stove top or stack temp in order to get a totally clean plume? I'm guessing yes, I need to have the top of the box and the baffle above some temp to get good secondaries. --Do you burn pretty hard when starting a new load, to get the stove up to temp fast and get the secondary burn going? I think that in the above burn, I just cut too much air too early, and even though I had some flame in the box, the secondary just never really got going. --How much control do you have over heat output? Between what stove top temps can you run, while still burning clean? If I fire the new load pretty hard and get a lot of wood burning, sure I'm burning clean with good secondaries but there's no dialing the stove top temp back down...it's just going to keep dumping secondary flame around the front of the baffle and the stove top is going to stay at about 700, no way I can turn it down, and it seems like it will burn up a sizeable load of wood pretty quickly, compared to what I'm used to with cat stoves. I haven't yet monitored the heat life of a load at her house in cold weather, but I'd certainly like at least some control over the output of the stove, and how long I can stretch the burn time of a load. With the stove top at 700, the surface magnet meter on the flue about 13" up is around 500...goodbye, heat. Maybe I will have to experiment with a second flue damper when it gets cold out, and draft gets even stronger than it is now at 40* outside. I'm thinking that with more control over the draft, I'll be able to burn hard at the beginning to get the plume clean, then cut the draft and slow the burn rate of the load, while still keeping the plume clean. --Are you able to burn clean, early in the load, even if you don't see a lot of secondary flames? I'm thinking that if one has cut the burn rate lower, less wood gassing, that these stoves may still be able to burn the smoke even if you don't see a lot of flame off the secondary...? Thanks in advance for your input!
