Disclosed herein is a self-assembly brazier. The self-assembly brazier includes: a pair of floor plates arranged bilaterally symmetrical to face each other; a pair of side wall modules having a plurality of side panels disposed to be rotatable, being combined with each other to face each other symmetrically so that a combustion space is formed, and being arranged on upper surfaces of the floor plates to be erected; and a pair of fuel loading parts seated inside lower portions of the side wall modules so that fuel is loaded on the upper surfaces of the fuel loading parts.

A heating device, preferably for the combustion of biomass, in particular of pellets of biomass, in one aspect, includes a burner part and a heating part. The burner part includes a combustion chamber; a double-walled, internally hollow combustion-chamber wall, which has an upper opening leading above the combustion zone into the combustion chamber; a flue-gas duct which leads the flue gas downwards along the combustion chamber, wherein the flue-gas duct is followed by a heat-exchanger area including initially, a flat-tube flue-gas heat exchanger, then, a tertiary-air heat exchanger; a flue-gas ventilation stack, a radiant-heat exchanger located above the combustion chamber, a flue-gas flap at the upper end of the flue-gas duct, which, when open, connects the flue-gas duct to the stack. A flat-tube flue-gas heat exchanger of the heating part forms a heat-exchanger circuit with an exhaust-air heat exchanger with the same heat-transfer medium as the flat-tube flue-gas heat exchanger.

A burner for burning fuels and modular heat utilizing appliances therefor. The burner includes a fuel holder, an outer wall surrounding the fuel holder and defining a combustion chamber, and optionally, a second wall surrounding the outer wall. Air is inducted from an inlet which may be an ash pan pivotally coupled to the outer wall at the bottom to open the combustion chamber. Supplementary combustion air is conducted to just above the fuel holder by the outer wall. Additional supplementary combustion air is conducted to just above the fuel holder by the second wall. The burner may include a pivotally mounted cooking grate and a pivotally mounted solid cover for closing the combustion chamber, and supporting legs. Modules individually yet replaceably attachable to the burner include a closed or open cooker, a smoker, a space heater, and a pyrolyzer.

Disclosed herein is a partition wall assembly for a stove. The partition wall assembly for a stove includes a plurality of partition walls (100, 100a, 100b, 100c). Each of the partition walls includes: an outer panel (110) having first air intake holes (111a) formed at a lower portion thereof so that first air is induced; an inner panel (120) coupled to the inside of the outer panel (110), and having an air moving space (119) formed between the outer panel (110) and the inner panel (120) so that the first air induced through the first air intake holes (111a) moves in the air moving space (119) while temperature of the first air is elevated, and second air outlets (121b) formed at an upper portion thereof to discharge the second air with the elevated temperature toward fuel; and a pair of side coupling members (130) disposed at both sides of the outer panel (110) to couple the outer panel (110) and the inner panel (120) with each other. The inner panel (120) includes: an inner panel body (121) curved to have a predetermined curvature in a height direction; a lower inside coupling plate (122) extending from a lower portion of the inner panel body (121) to a predetermined area and coupled with the outer panel (110); and an upper inside coupling plate (123) extending from an upper portion of the inner panel body (121) to a predetermined area and coupled with the outer panel (110).

A solid fuel burning cabinet circular heating appliance achieves improved emissions performance by providing a secondary air combustion path that preheats secondary combustion air. The firebox is selectively insulated such that areas of the firebox that do not preheat combustion air retain heat in the firebox while areas of the firebox that transfer heat into the combustion air transfer heat through the firebox into the incoming combustion air. The exhaust air path from the firebox to a chimney is also uninsulated to allow relatively quick heat transfer into a room in which the appliance is installed

A fire an inner chamber wall circumscribing and defining an inner chamber. A plurality of primary air apertures defined through the inner chamber wall at a first, lower level and a plurality of secondary air apertures defined through the inner chamber wall at a second, upper level. A fuel grate is supported within the inner chamber at a level between the lower level and the upper level. Solid fuel supported by the fuel grate, when combusted, is provided primary combustion air from below the fuel grate by the primary air apertures and provided secondary combustion air from above the solid fuel by the secondary air apertures, the secondary combustion air promoting combustion of unburned gasified combustibles rising within the inner chamber.
