Abstract

A method for combusting a wood log includes positioning the log within a combustion chamber with the log first end positioned above the log second end so that the log longitudinal axis is generally angled relative to and adjacent the chamber base wall and so that the log and the chamber base wall define a generally triangular air volume therebetween. The log is maintained in the angled configuration during at least part of the combustion process. A log supporting structure facilitates use of the method. The structure includes a supporting rod and a spacing base extending from the latter for resting on the base wall of a combustion chamber. The spacing base has a generally flaring configuration and allows gas to flow between the chamber base wall and the supporting rod in a first flow direction generally parallel to the supporting rod, and in a second flow direction generally perpendicular to and away from the rod from the log first end toward the log second end.

Dependent claims

A log supporting structure for supporting a log positioned within a combustion chamber, said log having a generally elongated configuration defining a log longitudinal axis, a log circumferential surface, a log first end and an opposed log second end, said combustion chamber defining a chamber base wall and having a gas contained therein;

said log supporting structure comprising:
a generally elongated supporting rod defining a rod longitudinal axis, a rod circumferential surface, a rod first end and an opposed rod second end, said supporting rod for supporting said log first end at a predetermined location therealong so that said log longitudinal axis extends in a generally perpendicular relationship relative to said rod longitudinal axis and in an angled relationship relative to and adjacent said chamber base wall with said log first end positioned above said log second end;
a spacing base extending from said supporting rod for resting on said chamber base wall and maintaining said supporting rod in a predetermined spaced relationship relative to said chamber base wall;
said spacing base having a generally flaring configuration in a geometrical plane generally perpendicular to said rod longitudinal axis and in a direction leading away from said supporting rod;
said spacing base being provided with a longitudinal venting means for allowing said gas to flow between said chamber base wall and said supporting rod in a first flow direction generally parallel to said supporting rod at least partially along said supporting rod;
said spacing base being provided with a transversal venting means for allowing said gas flowing in said first flow direction to flow in a second flow direction generally perpendicular to and away from said supporting rod at said predetermined location along said supporting rod and generally parallel to said chamber base wall from said lop first end toward said log second end.

A method for combusting a wood log inside a combustion chamber, said combustion chamber having an air inlet, an air outlet;

said wood log having a generally elongated configuration defining a log longitudinal axis, a log first end, a log second end, a log length, a log diameter and a log circumferential surface, said method comprising the steps of:
positioning said log within said combustion chamber generally adjacent said chamber base wall in a combustion configuration wherein said log first end is at a first spacing distance relative to said chamber base wall and wherein said log second end is at a second spacing distance relative to said chamber base wall, said first spacing distance being greater than said second spacing distance so that said log longitudinal axis is generally angled relative to and adjacent said chamber base wall and so that said log and said chamber base wall define a generally triangular air volume therebetween;
ensuring that said air volume between said log and said chamber base wall allows circulation of air generally thereacross in both a first direction generally perpendicular to said lop longitudinal axis adjacent said log first end and a second direction generally parallel to said chamber base wall from said log first end toward said log second end;
igniting said log;
and
maintaining said log in said combustion configuration during at least part of the combustion of said log.
