GAS FLOW SWIRL GENERATOR Russian patent published in 2002 - IPC

FIELD: air spraying, liquid fuel atomizing, stack gas circulation in boiler furnaces burning fuel of any kind. SUBSTANCE: device has hollow cylindrical housing with admission and discharge pipe connections and screw conveyer installed along housing axis and equipped with hollow blades and central perforated duct with interblade holes. Novelty is that additional swirling member is provided in the form of boss on front wall of blades that has through guide ducts running to screw conveyer space. Perforation holes of central duct and guide ducts are threaded+ADs- part of gas flow is admitted to hollow blades due to entry edge on blade first along gas flow. Proposed design ensures fast and high-quality dispersion and atomization of liquid fuel fed to combustion chamber or circulation of stack gases, as well as more efficient burnout. EFFECT: enhanced heat energy generation efficiency. 4 cl, 1 dwg
