BURNER Russian patent published in 1999 - IPC

FIELD: power engineering; combustion of heavy liquid fuels in mobile and stationary steam boilers. SUBSTANCE: burner has air duct, converging-diverging nozzle, ring fuel chamber connected with nozzle neck through fuel feed radial channels, and adjusting cone. Converging-diverging space is made along longitudinal axis of adjusting cone. This space accommodates fuel feed pipe whose outlet hole is located on its longitudinal axis stationary relative to converging-diverging nozzle. Adjusting cone is installed on longitudinal axis of nozzle for translational movement along axis and for possibility of contact with nozzle surface. EFFECT: provision of complete combustion of fuel with excess air coefficient 1.05 at wide range of capacity regulation. 2 cl, 2 dwg
