Disclosed is a particle heating landscape furnace, which includes a combustion device. The combustion device includes a vertically arranged cover pipe, a grid and a combustion assembly. The combustion assembly has a feed chamber, a flame outlet and a flame outlet opposite to the flame outlet. A feed chamber is arranged obliquely, the flame outlet and the discharge port are both connected with the feed chamber, and the cover pipe is arranged on a periphery of the flame outlet, the grid is arranged on an outer side of the discharge port.

An enriched air stove having a combustion surface for supporting solid fuel for combustion and an oxygen enriched air intake fluidly connected to the combustion surface to provide an oxygen enriched air source. The combustion surface can be a baseplate comprising a plurality of apertures fluidly connected to an air mixing chamber to mix atmospheric air and enriched oxygen to assist combustion of the solid fuel.

An apparatus in which a solid fuel mass is burned controls the burn rate to slow the burning process and extend the lifespan of the solid fuel mass. The apparatus has a base cup configured to receive a lower portion of the solid fuel mass, and a descent cup configured to receive an upper portion of the solid fuel mass, wherein the descent cup includes a flame orifice. The descent cup is telescopically associated with the base cup and moves toward the base cup as the solid fuel mass is burned, and a flame produced as the solid fuel mass is burned extends outwardly from the flame orifice of the descent cup.
