Question: 1 / 400

Which type of burner supplies combustion air using a mechanical device like a fan?

Natural draft burner

Forced draft burner

A forced draft burner is designed to supply combustion air using a mechanical device, typically a fan. This system works by actively pushing air into the combustion chamber, ensuring a consistent and adequate supply of air for efficient combustion. The use of a fan to facilitate air movement allows the burner to operate effectively regardless of external conditions, such as changes in atmospheric pressure or wind influences, making it ideal for applications that require precise control over the combustion process.

In contrast, a natural draft burner relies on the buoyancy of hot gases to draw air into the combustion chamber, which can be less reliable in certain conditions. An indirect vent burner and an open flame burner have distinct functions that do not primarily involve mechanical assistance in air supply, further highlighting the unique role of the forced draft burner in ensuring optimal combustion efficiency.
