Force draft combustion blowers ______ air into the combustion chamber.

Force draft combustion blowers ______ air into the combustion chamber.

• A. Draws
• B. Forces
• C. Pushes
• D. Recirculates

Answer: (B)

In a forced-draft setup, the blower creates positive pressure and pushes air into the combustion chamber. This active pushing of air ensures a steady supply of combustion air delivered through the ducts to the flame. Saying air is drawn would describe induced-draft systems, where suction pulls air through the chamber. Recirculating would imply looping air back rather than supplying fresh combustion air. So, forcing air into the chamber best captures the action of a force draft combustion blower.
