Boilers are pressure vessels designed to heat water or produce steam, which can then be used to provide space heating and/or service water heating to a building. In most commercial building heating applications, the heating source in the boiler is a natural gas fired burner. Oil fired burners and electric resistance heaters can be used as well.

Draft - Combustion Technology

Forced draft boilers run a positive pressure from overfire, through to the stack termination. The entire system must be welded or otherwise sealed tightly to prevent flue gases from escaping. Also, the height of the vent termination must be limited (generally 15 feet from the breech) to prevent a negative draft.
