COMBUSTION APPARATUS

摘要

A combustion apparatus capable of producing the recirculation of combustion gas by positively controlling the recirculation by a simple structure. The combustion apparatus comprises an annular container (12) having an inner tube part (15) forming an inner peripheral side face, an outer tube part (13) forming an outer peripheral side face, an open end part (26), and a closed end part (10). An air flow (28) having a speed component in the direction of a center axis (J) starting at the open end part (26) toward the closed end part (10) and a speed component in the circumferential direction of the annular container (12) is formed in the apparatus. A fuel (23) is jetted to have a speed composition in the direction of the center axis (J) starting at the closed end part (10) toward the open end part (26) and a speed component in the radial outer direction.
