Note that a catalyst stove burns more cleanly at lower burn rates. These byproducts then generally burn at around 500 degrees, much lower than a non-catalytic stove, which needs a temperature of 1100 degrees. This allows users to burn cleaner at low burn rates, resulting in less wood consumption and overall higher efficiency. Efficiencies average around 78% (with a range of 63- 84%) using the higher heating of fuel (HHV). The device is chemically coated with a metal that reacts with smoke and other combustion byproducts. Inside the stove, the smoky exhaust passes through a coated honeycomb (the catalyst). A wood stove catalytic combustor is comparable to a catalytic converter in a car.

This process is called catalytic combustion. Some wood-burning stoves make it easier burn fuel by using a chemical process which decreases the formation of pollutants. What is the difference between catalytic and non-catalytic wood stoves? Selection of Stoves and Accessories What technologies do certified stoves use to improve efficiency and reduce emissions?Ĭertified appliances typically use a catalyst, secondary combustion, or a combination of the two technologies (hybrid) to meet the emission requirements.
