BURNER WITH INTERNAL COMBUSTION Russian patent published in 2012 - IPC F23C3/00 F23C7/04 F23M5/08 F23R3/28 C03B37/04 F23D14/78 

FIELD: power industry.

SUBSTANCE: burner (1) with internal combustion, which includes combustion chamber (2) fed with fuel and fuel oxidiser, besides, the above combustion chamber includes cover (20) equipped with the first closed end (21) and second open exhaust end (22) which is opposite to the above first end, through which gaseous combustion products are removed. Cover (20) has at least two opposite walls (24, 25) which connect two of the above ends (21, 22) to each other. Burner includes at least two burning devices (3 a, 3b) in combustion chamber (2) and on the level of its first closed end (21), which are fed with fuel and fuel oxidiser, the configuration of which differs from each other so that two different types of flame can be created. Besides, the above burner is equipped with cooling system of its walls (24, 25) by means of introduction of cooling gas moving along the above walls. Cooling system includes multiple holes (26) passing through walls (24, 25) through which air is absorbed, as well as deflector plates (28) located inside combustion chamber (2), each of which forms cavity (29) on one side, which is located opposite several holes (26) and which is intended to receive the air supplied from the above holes, and on the other side it is provided with guide slot (29a) that is intended to discharge the air from the above cavity to inner space of combustion chamber (2). Walls (24, 25) of combustion chamber are provided on their external surface (24a, 25a), outside the combustion chamber, with multiple projections (27) which pass along minimum length of its wall and at the level of which there are through holes (26). Between the above projections (27) there made are platforms (27a) which have the shape of X-tree and the inclination of which is oriented in the direction of burner exhaust end (22).

EFFECT: small overall dimensions.
