Abrégé

The proposed utility model relates to thermal engineering and concerns a combustion chamber of a solid-fuel boiler which runs primarily on bio fuel in the form of pellets. The combustion chamber of a solid-fuel boiler comprises a branch pipe for supplying secondary air, а vertical screen made of two hermetically sealed metal cylinders, i.e. an inner cylinder and an outer cylinder, secondary air outlet nozzles, and a radiator designed as a vertical metal cylinder and installed between the inner cylinder and the outer cylinder of the vertical screen, opposite the nozzles. The invention is novel in that the secondary air outlet nozzles are configured at the top and bottom of the inner cylinder of the vertical screen, wherein the axes of the secondary air outlet nozzles of an upper row and the axes of the secondary air outlet nozzles of a lower row mutually intersect in pairs. The technical result of this utility model consists in the reduced required amount of secondary air, the increased efficiency of the boiler and the increased duration of autonomous operation of the boiler.
