Exhaust Temperature Coming Off the WL110

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.

Matt, Dave or anyone that's measured this, anyone know what the temps are coming off the top. Full bore burn, what's the max you would expect to see?

Flue gas temp @ 200* F water temp would be between 300*F and 375*F depending on coal and how clean the boiler is and coal quality.

So has anyone used aluminum tubing for venting?

No you haven't tried it, or no it won't work?

Seems to have the chem resistance needed.

No, I have not tried it. Aluminum vent pipe is only approved for gas installations...it doesn't have sufficient resistance to corrosion to be used with fuel oil appliances, so I doubt it would last very long with coal.

I found some flexible rubber compounds with high temp ratings up to 550f, but it's about elebenty thousand dollars to do 12 feet.

Anyone paint the galvanized to improve corrosion resistance?

Galvanized is also a bad idea. It can gas off, which would not be healthy.

Not anywhere near the stack temperature that a stoker boiler runs...which is under most oil units.

I read it as: With the boiler water temperature @ 200F, the internal stack temperature should be 300F to 375F.

I had to do a double take on it. Not to nitpick, but if the "@" was to be replaced with the word "for" it would be easier to understand (properly).

For a New Topic...
How many members get their boiler water temps up to 375* F?
And if you have, did you have any leaks?
