Abstract
A grate assembly for guiding air into a pile of combustible wood pellets for combustion thereof. The grate assembly includes a structural subassembly having at least two sets of elongate members, a first one of the two sets forming a lower layer for at least partially supporting a second one of the two sets forming an upper layer. The grate assembly also includes a support element attached to the structural subassembly. Each member includes a body at least partially defining one or more channels and a number of holes in fluid communication with the channel(s) to guide air into the pile of the wood pellets. The support element includes a base portion with a plurality of apertures, for ignition of the pellets therethrough
Claims18
A grate assembly for guiding air into a pile of combustible wood pellets for combustion thereof, the grate assembly comprising:
- a structural subassembly comprising at least two sets of elongate members, a first one of said at least two sets forming a lower layer for at least partially supporting a second one of said at least two sets forming an upper layer;
- each said member comprising a body at least partially defining at least one channel and comprising a plurality of holes in fluid communication with said at least one channel to guide said air from said at least one channel into the pile of the wood pellets;
- the members being spaced apart from each other in a predetermined arrangement to distribute said air into the pile of the wood pellets;
- at least one support element attached to the structural subassembly;
- and
- said at least one support element comprising a base portion with a plurality of apertures, for ignition of the pellets therethrough.
A grate assembly for guiding air into a pile of combustible wood pellets for combustion thereof, the grate assembly comprising:
- a structural subassembly comprising at least two sets of elongate members, a first one of said at least two sets forming a lower layer for at least partially supporting a second one of said at least two sets forming an upper layer;
- each said member comprising a body at least partially defining at least one channel and a plurality of holes in fluid communication with said at least one channel to guide said air from said at least one channel into the pile of the wood pellets;
- the members being spaced apart from each other in a predetermined arrangement to distribute said air into the pile of the wood pellets;
- and
- at least one support element attached to the structural subassembly, for at least partially retaining at least a portion of the pile of combustible wood pellets on the structural subassembly.
A grate assembly adapted to be positioned in a firebox at least partially defined by a rear wall and a front wall having an opening, for guiding air into a pile of combustible wood pellets for combustion thereof, the grate assembly comprising:
- a structural subassembly comprising at least two sets of elongate members, a first one of said at least two sets forming a lower layer for at least partially supporting a second one of said at least two sets forming an upper layer;
- each said member comprising a body at least partially defining at least one channel and a plurality of holes in fluid communication with said at least one channel to guide said air from said at least one channel into the pile of the wood pellets;
- the members being spaced apart from each other in a predetermined arrangement to distribute said air into the pile of the wood pellets;
- at least one support element attached to the structural subassembly, said at least one support element comprising a base with a plurality of apertures, for ignition of the pellets therethrough;
- and
- the structural subassembly being positionable in the firebox such that said at least one support element is accessible via the opening in the front wall.
