What is the term for when a stove emits smoke in short, sharp puffs due to a series of small explosions?

The phenomenon referred to when a stove emits smoke in short, sharp puffs due to a series of small explosions is known as back puffing. This occurs when the combustion process is unstable, often due to issues such as improper airflow or a blocked chimney. The results can be quite dangerous, as the smoke being released into the living space can contain harmful gases.

Back puffing is typically characterized by the smoke appearing in quick bursts, creating a noticeable puffing rhythm as opposed to a steady release of smoke. Understanding this term is crucial for chimney sweeps and maintenance professionals, as it helps them identify combustion issues and address safety concerns in heating appliances.

Other terms related to ventilation, combustion failures, and smoke movement may imply similar issues but refer to different phenomena, making back puffing the appropriate term for this specific situation.
