Which is an error that can occur in a combustion process?

Incomplete combustion is a significant error that can occur in a combustion process. This phenomenon typically happens when there is insufficient oxygen available to completely burn the fuel, resulting in the production of carbon monoxide, soot, and other harmful pollutants instead of clean carbon dioxide and water. Incomplete combustion can lead to reduced efficiency, increased emissions, and potential safety hazards due to the formation of toxic gases.

Ensuring proper airflow and fuel mixture is crucial for achieving complete combustion; otherwise, the operation of the combustion system may become inefficient, leading to higher operational costs and environmental concerns. Understanding this process is fundamental for HVAC professionals, as it directly impacts the performance and safety of heating systems.
