If a special glass ceramic increases the effect of catalysts in a wood-burning stove, its dust emissions will decrease. This is shown by a development project of the companies Blue Fire and Schott.
Blue Fire and Schott cooperate on dust reduction of wood furnaces
Catalysts have a specific reaction temperature. This is the temperature at which the catalytic reactions that reduce emissions begin. In order for the catalytic effects and thus the emission reductions in wood firing systems to start as soon as possible after the wood is lit, the reaction temperature should be as low as possible. So the more heat that remains in the combustion chamber of a wood stove, the more energy is available and quicker to heat a catalyst. This was the task set by catalyst manufacturer Blue Fire and glass manufacturer Schott. Using the latest coating technology, Schott has managed to make the fire viewing pane of a wood stove radiate a large proportion of the heat radiation emitted by the fire and embers - "16 times more than an uncoated viewing pane", the company assures.
Heat-reflecting glass ceramic makes catalytic converters work faster
The two companies use this effect in their research project to exploit the significantly higher heat in the combustion chamber to heat the Blue Fire catalytic converters quickly and selectively. They conducted the tests on a three-sided glazed stove, among other things. Result: The coated Schott glasses significantly reduced the time until the reaction temperature was reached. The result: CO and dust emissions from fireplaces equipped with the glasses are reduced by almost half, according to a company statement. "The results are promising and offer very good combination possibilities for the manufacturers of wood-burning appliances to be able to develop innovative and low-emission products and bring them to market," is the conclusion of the project partners.
