MULTIFUEL BURNER Russian patent published in 1999 - IPC

FIELD: heat power engineering, applicable at joint-separate combustion of fuel of different types, such as liquid fuel, gas. SUBSTANCE: the burner has axially arranged burner handle with a nozzle, coupled to the liquid fuel branch- pipe through a flexible connection, primary gas manifold with slots and mixer communicating with gas and inert atmosphere branch-pipes through flexible connections, primary air duct with hollow blades with walls forming cavities communicating with the manifold through slots, plate blades forming a primary air swirler - with the other wall, guide branch-pipe, flue gas distributors, each of them is U-shaped and located inside the duct before the flue gas swirler, connected to it, to the duct, to the branch-pipe; openings are provided opposite each distributor; the pipe-line around the duct forms a conduit connected to the flue gas branch-pipe, combustion chamber, flue gas swirler; secondary air duct accommodating the secondary air swirler of hollow blades, with slots and secondary gas manifold with a mixer located opposite them and connected to the blade cavities through the slots and to the gas and inert atmosphere branch-pipes. The hollow blades are trapezoid-shaped and have nozzle openings, and gas swirlers in them. The handle with the nozzle, manifold with blades are installed for joint axial movement and fixing by drive assemblies, and the plate blades - for longitudinal movement in the duct and fixing by bolts. EFFECT: enhanced reliability of the burner base members, primary gas manifold end part and face part of hollow swirling blades on the side of the combustion of liquid fuel and economical efficiency of fuel-consuming object. 2 cl, 8 dwg
