What is a danger of operating a boiler with inadequate airflow?

Operating a boiler with inadequate airflow presents significant risks, particularly related to increased emissions and the potential for explosions. Airflow is essential for the combustion process in a boiler; it ensures that the fuel burns properly by supplying the oxygen required for combustion. When airflow is insufficient, the combustion process becomes inefficient and can lead to the formation of harmful emissions, such as carbon monoxide and unburned fuel.

Additionally, inadequate airflow can result in an accumulation of combustible gases within the boiler, raising the risk of an explosion. This dangerous situation can arise because inadequate airflow causes incomplete combustion, leading to higher concentrations of flammable gases. Hence, ensuring proper airflow is critical not only for efficient operation but also for safety, as it minimizes these hazardous conditions.
