STEAM GENERATOR Russian patent published in 2007 - IPC F22B1/26 

FIELD: heat-and-power industry; devices for the steam generation.

SUBSTANCE: the invention is intended for generation of steam and may be used in the power plants. The steam generator contains the ignition device with the electric plug and the mains of delivery of the fuel and the oxidant, the mixing head with the fire bottom, collectors of the oxidant and the fuel and the appropriate mains, the chambers of combustion and mixing, the intermediate nozzle with the profiled walls, the unsert of feeding of the ballasting component with the mains of delivery of the ballasting component. The mixing head contains the triplet mixing components with provision of collision of the streams. The profiled butt wall of the intermediate nozzle disposed between the chamber of burning and the chamber of mixing is made optimized by the angle of introduction of the streams of the ballasting component into the plume of the combustion products and using the lines of flow of the ballasting component along this butt wall. The insert of feeding of the ballasting component is made with the holes ensuring diversity of the streams of the ballasting component. The invention ensures improvement of the characteristics of the mixture formation between the ballasting component and the plume of the combustion products, the decreased mass and the overall dimensions of the steam generator.

EFFECT: the invention ensures improvement of the characteristics of the mixture formation between the ballasting component and the plume of the combustion products, the decreased mass and the overall dimensions of the steam generator.
