This unit may wind up in the classified section, but before it goes anywhere I wanted to show some of the neat features provided by this vintage equipment. The International boiler with efficient water tube design is made of 5/16" steel. It's old enough to collect Social Security, but shows little wear. It features a large door that provides easy access to the combustion chamber and water tubes (for cleaning).

The stoker is an EFM 16A, predecessor of the S-30 unit that powers EFM 700's (with which it shares several components). In addition to variable feed/air controls, the 16A provides automatic ash removal, automatic removal of fines from the air chamber under the burn pot and a slide plate to stop the flow of coal from the hopper (e.g., to enable foreign objects to be cleared from the pot auger).

The thing I've found most fascinating is the cabinet for the stoker. It provides a hinged top with a built-in screen for removing foreign objects from the coal as it enters the hopper, a duct that permits the stoker to draw air from the top of the hopper (may help to control odors), external feed rate adjustment and detailed operating instructions printed on the access panel. And it's pretty enough that it wouldn't look out of place in a finished area (like Rob R's living room :lol: ).

That's enough metal for the boiler to be classified as a battleship!!!

Was this one of the units that could be setup for continuous operation with variable feed?

The feed control is similar to the newer EFM's in that it can be varied over a wide range of "teeth" and will happily run all day at pretty much any setting you like. In the "features" discussion I neglected to mention that there is an interlock between the feed and air controls, so once the air is dialed in for any given feed setting, changing the feed setting automatically changes the air setting to (approximately) the right value. One simple lever on the outside of the cabinet therefore can control the feed and air simultaneously. It takes some of the fun out for people who like to control those functions manually, and is one of those "high-tech" things that have vanished from the newer units.

Could you show the burn pot section and the ash taker outer part under it? There is a scraper??? that gets the ash to the auger?

Here you go. It's basically a 700 pot. The ash is swept over the auger by the rotation of the pot. I'll need to take a closer look at what it has for "wings".

No wisecracks over the missing stove bolts - pot not yet fully reassembled.

If I remember correctly those pipe plugs on the front line up with water tubes. The only way to clean the waterside of the tubes was to remove those plugs and run a brush down the water side of the tubes. That hatch is good to get flyash off the fire side but cleaning the waterside is a pain.

Yes, the plugs appear to line up with the tubes. AFAIK there is no way to brush the waterside of most/all of the firetube and plate boilers out there, so it seems like that should go down as yet another lost feature.
