Bob, I hope you don't find that you end up having your boiler shut down more than you like. Only way you will know is to try it I guess. Will you be able to adjust setting easily for high temp shut down?
Just a thought - can a barometric damper be installed on the stack of a Woodgun?
Just asking as they can make for a very easy to use cleanout spot - just push the damper open & clean it out through that opening. Saves messing with caps etc. - could even wire it closed when not cleaning if you had to.
If not, then nevermind.
The residue was all grey...nothing dark and it was a very fine power. Gas, I was hoping the cyclone was blocked as I would prefer that than trying to control chunks of hot coals entering the the horizontal run but when I pulled the ash back toward the cyclone it fell thru the vertical pipe and wound up in the pan. Actually, I don't think my cyclone has ever been blocked. It's cold here today too but not too bad, just came in from the barn and it's creeping toward 30 now.
Ken, I agree. I clean the boiler on a regular basis, just one more activity to add to the routine. I need to find an easier way to remove the cap on the T if I'm going to be doing this routinely. Thanks again for the info.
Fred, I am surprised that this happened now with the nozzle being barely a month old, I would have thought this would more likely have happened when I was stretching the use of the old deteriorated nozzle! The higher stack temps that I have observed have happened only when down to nothing but a thick layer of coals. Yesterday I cleaned the box of a lot of ash and some of the coal bed down to probably only a few inches thick. I noticed this morning in mid run that the stack temp was only 325-350.
My solution will be to install high temp sensor that will shut the boiler down. Giving my electrician buddy a call later.
