Over under firing how is it accomplished

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.
