REBUILD FIRE CHAMBER

TOM_132

<strong>THIS IS A QUESTION NOT A COMMENT. I COULDN'T FIND THE POST TO ASK A QUESTION.</strong>

 

I HAVE A AMERICAN OIL BURNING BOILER #S-0611 RATED TO HEAT 515 SQ. FT. OF STANDING RADIATION. THE BOILER WAS INSTALLED IN 1939. LAST YEAR I CHANGED THE OIL BURNER WITH A BECKETT MODEL 7505 AFG. THIS YEAR I AM REPLACING THE FIRE CHAMBER WITH INSULATED FIRE BRICK RATED AT 2,600 DEGREES. PRIOR TO INSTALLING THE IFB'S I SOAKED THE BRICKS THEY ABSORBED A LOT OF WATER AND THE JOINTS NEVER SEAMED TO HARDEN PROPERLY. WHEN I FIRED THE BURNER IT WOULD ONLY STAY ON FOR ABOUT 10 SECONDS AT A TIME DUE TO THE RETAINING A LARGE AMOUNT OF WATER. WHEN I FINALLY DRIED THE BRICKS OUT SOME OF THE BRICKS SEPARATED FROM THE JOINTS AND SOME CRACKED. THE QUESTION IS DO I HAVE REINSTALL THE FIRE BRICKS ALL OVER AGAIN AND <strong>NOT SOAK THEM</strong> OR IS THEIR ANYTHING ELSE I CAN DO?

rebuid fire bricks

yes rebuild the chamber and waste energy or buy a new boiler and save energy if you want to waste money rebuid the chamber this time do not soak them in water who ever told you to soak them has never replaced a chamber do your self a favor spend on a new boiler it will save money in the long run

line the chamber

Fill behind the bricks with Mica pellet, and line the inside of the chamber with Lynn wet pack liner, and save for a new boiler.

Instead of fire bricks

I'd use a "bathtub" chamber made of Kaowool. I'm pretty sure the 11-series boilers are wet-base units, and the bathtub is the proper chamber for such a boiler. If it's dry-base, a different type of chamber would be used.



But the others are right when they say it's time for a new boiler. Even with the Beckett burner and a new chamber, your 0611 will not be as efficient as a modern boiler.



If you just can't afford to replace it now, have the chamber installed by a pro who has a digital combustion analyzer and the know-how to use it. Then your 0611 will be as good and efficient as it can be.

well said Frank

 Quickie 300 is the largest Lynne bathtub chamber made. Trying to jog my memory of this model A/S, and what the firing rate is,
