A burning cell for solid waste fuel materials comprises a lower cylindrical chamber where a pile of said waste fuel is burned with the aid of a plurality of horizontal arrays of tuyeres that feed the air against said pile, and an upper cylindrical chamber separated from said lower chamber by a centrally opened partition, said upper chamber having a helical array of downwardly inwardly and sidewardly inclined tuyeres to produce an outer descending whirlpool of air which reverses direction at said partition to form a central ascending whirlpool of air, said upper chamber having a centrally opened roof for exhausting said air, whereby the large particle fuel is totally burned in said pile in the lower chamber, whereas the partially burned fines are entrained by the air from said lower chamber tuyeres and passed upwardly into the central ascending whirlpool through said upper chamber to furtherly burn said fines without any contact between said fines and the walls of said upper chamber.
