Catalytic Combustor Functionality

A catalytic combustor is a device used in wood-burning fireplaces and stoves to improve the efficiency of combustion and reduce the amount of pollutants emitted into the atmosphere.

The combustor is made of a ceramic or metal honeycomb-like structure coated with a catalyst, usually made of precious metals such as platinum, palladium, or rhodium. When the smoke from the fire passes through the combustor, the catalyst helps to break down the unburned gases and particles, allowing them to burn more completely.

The result is a hotter and cleaner burning fire, with fewer emissions of carbon monoxide, nitrogen oxides, and particulate matter. This makes the fireplace or stove more efficient, reducing fuel consumption and saving money, while also reducing air pollution and improving indoor air quality.

Catalytic combustors require periodic maintenance, such as cleaning and replacement of the catalyst, to ensure proper functioning.
