Old Unit New Unit Baffles

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.

Did a 520 built in 56 use the same baffles as are being used today. Baffles I have found on my antiqure are some spiral interior tube flow guides and a cast iron baffle . I see no other baffles as described on modern day pictorial . Can anyone enlighten me ?

No. Not the same. The boiler design was changed several times of the past 60 years. They are probably turbulators/spinners, akin to the same used today in tube boilers, which increase efficiency. In a coal boiler, with flyash, they probably became a nuisance.

coalberner or scrapper can better answer your question.
