What is the function of forced draft in boiler operation?

Explanation:
Forced draft pushes air into the furnace, supplying the oxygen needed for combustion and creating positive pressure in the combustion chamber. This ensures a stable, efficient flame and allows greater control of the firing rate and furnace operation. It’s separate from removing exhaust gases (which is the job of the induced draft) and from feedwater preheating or flame suppression, which are handled by other systems.
