What is Pressure Draft in Furnace?

In the context of a furnace, Pressure Draft (also known as forced draft or positive pressure draft) is a method used to create a controlled flow of air or combustion gases within the furnace system. The pressure draft is achieved by using mechanical means, such as fans or blowers, to force air into the furnace and maintain a positive pressure inside the combustion chamber.

What is Significance of Pressure Draft in Furnace?

In a pressure draft system, the air is pushed into the furnace, ensuring that the pressure inside the combustion chamber is higher than the atmospheric pressure outside. This positive pressure helps to prevent any leakage of combustion gases and ensures that the flames and combustion process remain contained within the furnace.
