High-capacity sparkless mobile double-insulated wood pellet burner unit

A high-capacity sparkless mobile double-insulated wood pellet burner unit, comprising:

• an outer housing;
• an inner combustion vessel disposed within the outer housing;
• a horizontally oriented continuous planar disk inner insulation layer disposed beneath the inner combustion vessel within the outer housing, wherein the inner insulation layer extends at least from a first outer edge of the inner combustion vessel to a second outer edge of the inner combustion vessel, and wherein the first outer edge is situated opposite to the second outer edge;
• a continuous planar disk outer insulation layer having no apertures therein, wherein the outer insulation layer is disposed beneath the entire inner combustion vessel and beneath the entire inner insulation layer, wherein the outer insulation layer is spaced apart from the inner insulation layer, and wherein the outer housing is disposed on the outer insulation layer;
• and
• an air pap disposed between the outer housing and the inner combustion vessel,
• wherein:
• the outer housing includes one or more air intake vents;
• the one or more intake vents are disposed in the outer housing midway between a top of the outer housing and a bottom of the outer housing;
• the one or more intake vents are configured to receive outside air;
• the inner combustion vessel includes one or more lower vessel apertures and one or more upper vessel orifices;
• the air pap is configured to divide the outside air into a first branch having downward flowing heated combustible air in the air gap, and a second branch having upward flowing heated combustible air in the air pap;
• the one or more lower vessel apertures are configured to receive the heated combustible air from the first branch;
• the one or more upper vessel orifices are configured to receive the heated combustible air from the second branch to feed sparkless flames having a base at or near the upper vessel orifices;
• and
• each of the lower vessel apertures has a larger area of opening than each of the upper vessel orifices.
