Are there any other Vigas 60 or 80 guys having problems getting their front nozzle to gasify properly? My 80 has been running for a month or so now and I notice every time I peek in the lower door the rear nozzle will be gasing like crazy and the front has a lazy flame, bursts of flame, or no flame at all. My wood is averaging 18% moisture, and the problem doesn't seem to change if I change species or quality of firewood. My flue temps tend to run in the 170 - 210 range at most and I have a very sooty lower chamber - both I attribute to the flood of 'unburnt' air out of that front nozzle. Reaching in there with a cold boiler, as near as I can tell ( I can barely reach the rear) the front nozzle is delivering as much or more air as the rear. I have no idea where the lambda control is sending the air when I stick my hand in there, so I don't know if it's all primary or secondary air. I was suspicious the holes thru the nozzle perhaps don't line up with those in the outer portion of the floor, but don't know how else to check ( perhaps a borescope ? ) Since I don't have my 2000 gal storage hooked up yet, I'm idling a lot and my boiler is way oversized for my loads ( but man do I love that huge firebox ). Even when I'm playing catch-up on water temp and it's burning hard for a while it works the same. Any thoughts are welcome.
