In the spray combustor, an air supply cylinder (1) and a combustion cylinder (3) having an auxiliary air supply cylinder (2) on the outer periphery are connected via an air inflow plate (4), and these air supply cylinders (1) are connected. The auxiliary air supply cylinder (2) communicates with the air inlet plate (4) by providing a large number of vent holes (5), and is fixed to the center of the air inlet plate (4) by a nozzle holder (6). Combustion injection nozzles (7) of the swirl injection valve and the air flow injection valve are provided, and a plurality of air jet holes (8) are formed around the nozzle (7),
The auxiliary air supply cylinder (2) and the combustion cylinder (3) are provided with a plurality of auxiliary air supply holes (9) on their wall surfaces.

る。(Operation) Next, according to the present invention, the collision angle (θ) between the air jet and the fuel spray is changed by changing the angle of the air inlet plate (4) with respect to the central axis (X) of the air jet hole (8). Then, the air jet exiting the air jet hole (8) penetrates the fuel spray and rapidly mixes the fuel and air. At this time, a circulating flow is generated outside the air jet, and a part of the entrained fuel is burned to form an annular flame around the jet stream of air. The air jet is heated by the air jet flowing into the combustion tube through the hole (9), as a result of which the evaporation of the fuel by the high temperature air jet is promoted, and further the vaporized fuel and air are rapidly mixed and the main combustion region A flame is a flame that burns with a blazing flame. Further, the mixed state of fuel and air is controlled by a plurality of auxiliary air supply holes (9) formed in the auxiliary air supply cylinder (2).

る。(Effects of the Invention) According to the present invention, the flame retardant combustor of the present invention can be formed compactly without providing an evaporative mixing chamber in particular, a flame of clean combustion gas can be obtained with a flame retardant, and the combustion furnace wall can be made thin. It can be formed, and the jet of air is made to collide with the spray at a constant angle, and air is introduced from the auxiliary air supply cylinder (2) to obtain clean combustion gas, which is a very useful effect.
