What results from improper oxygen levels or combustion in a boiler?

Carbon dioxide
Carbon improvement
Carbon monoxide
Heat loss

The correct answer is: Carbon monoxide

Improper oxygen levels or combustion in a boiler can lead to the formation of carbon monoxide. This dangerous byproduct occurs when there is insufficient oxygen for complete combustion of fuel. Ideally, combustion should produce carbon dioxide and water vapor as the main byproducts. When the combustion process is not efficient—often due to inadequate air supply, poor mixing of fuel and air, or malfunctioning burners—carbon monoxide can form instead. Carbon monoxide is a colorless, odorless gas that is highly toxic to humans and animals, making it a serious safety concern in boiler operations. Understanding this relationship is crucial for maintaining safe and efficient operation of boilers, as well as for ensuring compliance with health and safety regulations.
