Embodiment Construction

[0026] refer to figure 1 A solid fuel stove 10 comprises a substantially cylindrical shell 11, a combustion chamber 12 formed in an upper portion of the shell and having a generally open upper side portion 15 serving as a cooking surface. The generally open upper side portion 15 includes a plurality of support columns 13 etc. on top for supporting cooking utensils such as pans. The generally open upper side portion 15 may be at least partially covered by a mesh, grid or other open structure (not shown) for further supporting the cooking vessel while still allowing efficient extraction of heat in an upward direction. The furnace 10 is preferably placed on a flat and stable surface 5 .

[0027] Opposite the open upper portion 15, the lower portion 17 of the combustion chamber 12 ( figure 1 Shown in dotted line) provides accommodation for solid fuel. Whenever a new supply of fuel is required, fuel is typically manually injected into the combustion chamber 12 through the open u...

Abstract

The invention relates to a solid fuel stove comprising a combustion chamber (12) for containing combustion fuel and a blower assembly (50) configured to provide airflow entering the combustion chamber in operating condition. When guiding means (40) establish airflow entering the combustion chamber substantially in a downwardly direction the combustion process of the stove is very clean and efficient.

Description

technical field [0001] The present invention relates to cooking ovens with improved combustion. In particular, the invention relates to cooking stoves capable of burning solid fuels such as wood using forced air circulation in the combustion chamber. Background technique [0002] An estimated 2.5 billion people worldwide burn wood for cooking. Known furnaces and processes are generally inefficient and have incomplete combustion, which causes significant soot emissions and contributes to the global warming process. Many deaths each year can be attributed to such polluting soot emissions. In addition, inefficient wood stoves use more natural wood resources and contribute to deforestation. [0003] During domestic wood burning, air pollution occurs due to incomplete combustion of volatiles released from the wood. Although volatile organic compounds are released from wood at temperatures as low as room temperature, the rapid release begins in large quantities only when the e...
