Red Seal Oil Heat System Technician Practice Exam

The role of combustion air in an oil heating system is crucial for the burning process of the fuel. Combustion air is necessary for the chemical reaction that occurs when oil is burned. This process requires an adequate supply of oxygen to ensure complete combustion, which maximizes efficiency and minimizes the production of harmful emissions, such as carbon monoxide. In the absence of sufficient combustion air, the burner may experience incomplete combustion, leading to increased soot production, lower efficiency, and potential safety hazards. Thus, providing the right amount of combustion air is essential for optimal performance and safety in an oil heating system.
