    Beckett burner, probably an AF, in an old National 3-pass boiler.

    Nozzle size and spray pattern depend on what the firing zone is like and the boiler's capacity. Getting everything in tune is a job for a pro.

    or do one better, after finding a contractor ask for a quote to replace it.

    You probably wont find that in the OEM spec book. You could look at the firing rate on the boiler, take the next size smaller nozzle, solid 80 degree and start from there. If it's not impinging on the sides or back. Then steady state, proper draft, then smoke test. When you get it to a one smoke, shut it down and replace the nozzle with the size nozzle, but a hollow nozzle. Get it up to steady state and see what the smoke number is, without adjusting the air band. If it's better, it takes a hollow. If it's worse, go back to a solid.
    Try to get it to a trace and see what the combustion numbers are.
    But @ichmb's answer is better

    You won't find that National boiler in the Beckett spec guide. It was probably installed during the 1940s or 1950s, with a National-branded oil burner. Not sure whether National built their own burners or subcontracted that to another maker. Beckett didn't start making that line of flame-retention burners until sometime in the late 1970s or early 1980s IIRC.

    Where complete replacement was not an option for whatever reason, we've upgraded a bunch of this type of boiler by installing burners like this, and properly baffling the flue passages. OK, this won't equal the efficiency of a new boiler, but it'll do better than what they had, especially since a properly-installed and tuned flame-retention burner will run through the entire season without making smoke or soot.

    In the days when coal-fired boilers were being converted to oil, this skill set was commonplace. Nowadays only the best can do it. That's the kind of person you need.

    Beckett AFG on National's version of the Arcoliner. You would not want the original burner that came on that. I don't miss them. This could be made to get some good #'s if one wants to. AF would be better on those older boilers I find. AFG is not needed. Steam boiler?

    Good point guys. Hadn't considered the age.

    :p

    Some days I wish I could shadow some of you guys. There's obviously a ton of knowledge floating around the forum.
