General curiosity about something I read in the book titled "The lost art of steam heating". How can a boiler be adjusted to over fire or under fire ?

    Oil or gas?

    Nozzle and or pump pressure on oil,pressure and or orifice on gas. This is not a DIY project,need a combustion analyzer and know what you are doing and why.

    Thank you for explaining the areas of the system altered. I have no intention of attempting adjustments of this kind. Just a fan of science, and how it is harnessed at home. Thank you so much for your knowledge contribution to my brain
