BOILER DESIGN Russian patent published in 2012 - IPC F23C5/32 

Abstract RU 2461773 C2

FIELD: power industry.

SUBSTANCE: boiler design with circulation combustion scheme is made so that combustion fuel and air supplied to combustion chamber from burners located on combustion chamber walls forming a rectangular section form vortex flow during combustion process. Air supply components are located near sections of combustion chamber wall surfaces, which are subject to flame action, which are approached by or with which flames come in contact, which are created with the corresponding burners, for creation of areas with air concentration that is higher than that in the periphery of those areas. At least one of the air supply components includes air duct formed with annular space between slag removal nozzle and the hole passing through combustion chamber wall.

EFFECT: effective reduction of corrosion formation and slag formation on combustion chamber walls.
