Ülepõletus

Ülepõletus is an Estonian term that translates to "overburning" or "overfiring" and refers to a condition that can affect wood-fired stoves and fireplaces. It occurs when excessive heat is applied to the masonry materials of the combustion chamber, often due to prolonged periods of very high temperature fires or a lack of proper ventilation. This intense heat can cause the bricks or other refractory materials to degrade over time.

Symptoms of ülepõletus can include visible cracks in the firebox, crumbling mortar, and a general weakening of the structure. In severe cases, it can compromise the safety of the appliance, leading to potential smoke leaks or even structural failure. The issue is more common in older constructions or when stoves are used for purposes beyond their intended design, such as burning unsuitable materials or maintaining excessively hot fires for extended durations.

Preventing ülepõletus involves careful operation of the wood-burning appliance. This includes maintaining appropriate fire temperatures, avoiding the burning of trash or treated wood, ensuring adequate airflow, and allowing the appliance to cool down gradually. Regular inspection and maintenance by a qualified professional can also help identify and address early signs of ülepõletus before significant damage occurs. Repairing affected areas typically involves replacing damaged bricks and mortar with suitable refractory materials.
