ABSTRACT:
A Vortex burner is provided in a burner block having a conduit spaced within the burner block passageway to provide an annular space between them. Fuel gas flows through the central portion of the burner, and is tangentially discharged through gas nozzles. Primary air is induced through the portion of the burner surrounding the fuel gas inlet means. Secondary air is induced into the burner through the portion of the burner surrounding the primary inlet means via draft. A deflector member disposed at a suitable angle to the primary air conduit and protruding from the discharge end of said conduit, directs the secondary air along the cup surface and causes it to mix with the partial premixture of primary air and gas. The deflector member aerodynamically directs the primary air and gas premixture along the cup surface. The secondary air flow prevents annular recirculation of hot gases. The design is utilized to maintain and improve mixing, to move the burner tip forward as far as possible into the furnace and to avoid annular recirculation of hot gases. A shallow rippled cup is also used to promote wall wiping.
