Old Tarm 501 Boiler

[Cold Cat]

I Have Tarm 501 Oil/Wood Boiler. It works great on oil but when i burn wood the creosote forms really fast. I,m not real sure how to adjust the secondary air inlets. The one on the side is open about a quarter of the way and so is the one on the loading door. The boiler is in pretty good shape and i want to keep using it but the buildup is starting to concern me. I have no bends in the pipe going to the stack and the chimney is clear. There's got to be something I'm missing.

Thanks,
Kevin

I don't know the model numbers all that well, so I don't know what you hav since google won't well me when I ask it Tarm 501, but the Tarms of the era of my avatar (skinned before I caught them at it) are creosote factories - uninsulated steel firebox, wall at 200F (or less) directly exposed to unburned gasses, lots of condensation, etc.

I have a project in mind for a little one with the skin still on it, basically consisting of insulating the firebox and making it more like a gasifier, where things get burnt before they meet the heat exchanger. We'll see.

Thanks for the reply, that sounds like exactly what I have. It's around 18 to 20 years old. I guess it's time to start the search for a good replacement. I'd like to stick with oil and gasification set up.
Thanks again
