Abstract: A pallet is formed of two or more sections formed of plastic materials. The sections are adjustably fixed together using elongated connectors dimensioned to fit closely in channels with each of the connectors extending between a channel of one section and a channel of an adjoining section. The sections and the connectors are adjustably secured together by mechanical fasteners. Spaced apertures are provided through each of the channels and similarly spaced apertures are provided through each of the connectors whereby the dimensions of the pallet are adjustable. Pallets are provided that can be nested in an inverted orientation without increasing the thickness of the inverted pair greater than the thickness of a single pallet.

Abstract: Stoves fueled by biomass pellets are provided with a grate assembly that supports the pellets for combustion and directs combustion gas into the fire. The grate assembly includes a passive grate of unequally spaced rods. The design of the rods serves to prevent the ash and clinkers from accumulating on the grate in amounts that could reduce the flow of combustion gas into the fire.

Abstract: Stoves fueled by biomass pellets are provided with a grate assembly that supports the pellets for combustion and directs combustion gas into the fire. The grate assembly includes a passive grate and a moveable elongate blade spaced above the upper surface of the grate to direct ash and clinkers through a plurality of elongate slots in the grate. The design of the planar plate and the movement of the blade serves to prevent the ash and clinkers from accumulating on the grate in amounts that could block the elongate slots and reduce the flow of combustion gas into the fire.
