Hello Eric, I have an old Axeman Anderson 260M boiler I'm refurbing to put into operation this winter. I am in the process of rebuilding the 1.5" raised lip that the end plate/fan shield/mount is gasketed to.
On my boiler the cast iron end plate has no shielding from the hot gasses and fly ash from the coal fire, and the unprotected inside surface of the mounting lip has erroded pretty badly from the blast of heat and ash.
Since I'm working on it in a very easy and accessable way right now, I'm thinking of upgrading this plate to the AHS ceramic shield and end plate. I can make a new end plate to fit anything, and new mounting tabs/system etc.
I spoke with forum member Yanche, and from his description of the end plate and ceramic shield on his AHS S130, I might be able to change my boiler to use your ceramic shield from an AHS S260, if the dimensions are similar. On the AA boiler, there are bolts used to mount the end plate, it is sefl-centering in the opening due to the inner lip on the plate fitting inside the boiler's lip. I would have to install mounting studs to support the AHS ceramic shield and an end plate.
The raised lip outside diameter on my boiler is roughly 15.5", but I can use as small as 14.75" up to 16" if needed, I would just adapt the mounting studs to fit the 'ears' on the ceramic shield.
Eric could you let me know the dimensions of your ceramic shield for your S260 boiler?? I'll then be able to tell if I can make this work. Also, the price of the shield would be appreciated. Either by post here or PM would be fine.
I have to believe that the ceramic shield would add a measurable increase in efficiency to the boiler. Yanche said the paint hasn't even bubbled on the steel plate over the ceramic shield on his S130, so the ceramic is deflecting and reflecting a significant amount of heat back into the heat exchanger.
On the AA boiler end plate there is a series of bumps for heat radiation on the outside of the plate, I'm assuming this is to keep the plate from getting too hot, It has to be near or at cherry-red after 15-20 minutes of fan operation.
Thanks Eric, Greg Long
