Steel Stoker Cleaning Brush

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

Does the self-cleaning action of the AA deposit ash dust in the flue pipe?

Then A-A Antratube and AHS Coalgun boilers both have cyclone type ash separators as part of the flue gas path. It deposits part, but not all of the flue gas ash in to the ash bucket. The fly ash that makes it through the cyclone still collects in the flue pipe. The cyclone size is way too small to removal all the fly ash. I've looked at the design equations for cyclone ash separators and an effective separator would need to be much larger, 18-20 inches in diameter.

OK, I got it. I have a cyclone dust separater in my wood shop. Properly sized, they work great.

In my opinion it's easier to seal a pipe thread, especially with modern high temperature silicone RTV, than it is to seal a flat plate. A pipe thread joint is a leak with a long spiral path, but you have multiple places on that path to make a seal. A much better design over the flat plate gasket design that depends on an adhesive or crushing of the gasket material for the seal.
Ageed I think thats why Keystoker & even Yellowflame used them for that Reason

Is this the brush? Quality?
That's it. What I would recommend is using the u-brush with a short chimney rod. Then get your self the "straight scout brush" . There is a plug in the end of the scout brush. Discard the plug and shove your short chimney rod in there as an extension.
For the furnace, you will need the noodle brush for cleaning the tubes in the rear section.These are flexible so you can turn them down and start them into the tubes. I also use the common millbury duster brush to reach up and clean off the top of the hanging baffle above the burner. Also, I use mini wire brushes to scrub the burner plates and a dentist's pick to open up the air holes that are stubborn.

This is a good thread. Just want to bump it. Has anybody tried the brush a couple posts back by Oilman? I use a toilet scrubber but it doesn't hold up. Right tool for the job :idea: :)
I think a man does what he can, untill his destiny is revealed. Right now that is trying to sell my EFM plate boilers in 520 and 700 sizes.

well, I'd have to agree with coalberner on this one, I've never seen an AA boiler in person, but, from the pics posted on here of black soot/flyash buildup in the flue pipe, it seems pretty surprising that they keep all the interior boiler surfaces that clean. My bit stokers will produce about 1/8" of sooty flyash per season (5ton) in the flue, and, without brushing, it builds up about that much in the heat exchanger every few weeks and then peels/flakes off and keeps on going. I've never seen flues clogged with as much dark flyash as I've seen on this site with AA type boilers. They probably are great boilers, but they seem to produce an abnormal quantity of dark flyash, especially in the flue.

I use the 2' long grill brushes. Works great. Lowe's sells them occasionally.
