What two problems can lead to the production of carbon monoxide?

The production of carbon monoxide, a dangerous gas, can occur due to flame impingement and incomplete combustion. When the combustion process in a heating system is not completed efficiently, it can produce carbon monoxide instead of the intended carbon dioxide.

Flame impingement occurs when the flames from the burner contact the combustibles or other surfaces in the combustion chamber, resulting in poor combustion and leading to the creation of carbon monoxide. Insefficient mixing of air and fuel can also occur, causing fuel to not burn completely, further contributing to carbon monoxide production.

Both of these issues are critical because they directly affect the efficiency of the combustion process and, more importantly, the safety of the heating system. Recognizing and addressing these problems is essential to prevent harmful gas production and ensure optimal functioning of the heating system.
