BOILER COMBUSTOR ALLOWING AVOIDANCE OF THERMAL NO Russian patent published in 2009 - IPC F23C3/00 F24H1/24 

FIELD: power engineering.

SUBSTANCE: boiler combustor contains combustor wall, outer water jacket inside combustor, inner water jacket installed inside outer water jacket and tilted outwards with diametre increase along height similar to trumpet combustion chamber located between outer and inner water jackets. Outer and/or inner water jacket consists of multiple parallel interconnected tubes and additionally includes multiple membranes connecting these tubes with each other. Outer water jacket is made with cross-section in the shape of rectangle or polygon or circumference. Outer water jacket is tilted inside decreasing in diametre as height grows. Inner water jacket is made with cross-section in the shape of circumference. Inner water jacket is tilted outside on top level. Combustor contains injectors for fuel injection into combustion chamber. The injectors are located at inner water jacket and are directed tangentially to inner water jacket. Inner water jacket consists of multiple parallel interconnected tubes, and in membranes connecting these tubes air vents are made to supply air to combustion chamber.

EFFECT: invention allows to avoid thermal NO_X and to increase heating capacity along with decrease in boiler dimensions.
