Catalytic unit for solid fuel burning stoves

Abstract

This invention describes a stove comprising a combustion chamber and a flue for removing exhaust from said combustion chamber, where said combustion chamber and said flue are connected via a passageway; said combustion chamber comprising a top and a bottom, where said top and said bottom are connected by one or more sides; a catalytic unit arranged between said combustion chamber and said flue in said passageway; said catalytic unit provides a guide way for the exhaust, where said catalytic unit comprises at least one isolating members and at least one catalytic member, said catalytic member comprising a first wave-like structure, said first wave-like structure being provided on at least one catalytic surface of said catalytic member and, in use, at least partly being in contact with the exhaust and, where, in use, the direction of the exhaust is substantially transverse to the waves of said first wave-like structure.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a solid fuel burning stove comprising a catalytic unit.BACKGROUND OF THE INVENTION[0002]Wood and coal burning stoves are employed for home heating and purposes such as cooking. However, especially the burning of wood often results in incomplete combustion and exhaust comprising a high amount of particles, volatile organic compounds and carbon monoxide, all of which are a hazard to the environment.[0003]Furthermore, the incomplete combustion results in a loss of overall combustion efficiency.[0004]In order to increase the combustion efficiency and minimize the pollution from the wood burning stove, the combustion temperature in the combustion chamber has been increased, and catalytic converters introduced into the stove.[0005]EP0037281 describes a wood burning stove with a combustion chamber and a flue, where a catalytic converter is located either in said combustion chamber or in the flue. The catalytic converter comprises...

AI Technical Summary

Benefits of technology

The present invention provides a stove that has a catalytic unit to reduce the exhaust of particles, carbon monoxide, and volatile organic compounds. This improves combustion efficiency and reduces negative effects on human health and the environment.

Problems solved by technology

However, especially the burning of wood often results in incomplete combustion and exhaust comprising a high amount of particles, volatile organic compounds and carbon monoxide, all of which are a hazard to the environment.

Furthermore, the incomplete combustion results in a loss of overall combustion efficiency.

If the pressure drop is too large, the combustion in the combustion chamber will be insufficient and result for example in a large amount of particles.
