Burner Using Pre-mixing Type For Coal And Cokes Tigh Temperature-Pressure Wet Type Entrained-Flow Gasification

摘要

The present invention pre-mix in the form of a hot-wet classification relates to appoint layer gasification burner for high pressure, it a burner body for, is arranged in the center of the burner body and a slurry supply pipe of the liquid to be supplied to the coal slurry state, is in communication with the slurry in the slurry supply pipe of the exhaust ball, the slurry supply pipe is exposed to the end of the burner body, and a first oxidant supply line disposed outside, in communication with the first supply line to the first oxidant nozzles arranged in the circumferential direction on the inner surface of the slurry supply pipe so as to spray the oxidizing agent to the inside of the ball and to the slurry supply pipe, and a second oxidant supply line disposed outside of the oxidant to the first supply line, the second is in communication with the second nozzle with an oxidizing agent supply pipe arranged in a circle along the slurry exhaust hole is exposed to the end of the burner body, ball, is releasably coupled to said second nozzle comprises a nozzle assemblies jidoe ball which is installed in the slurry discharge hole inclined direction, the coal slurry is motile by the primary oxidant is injected through the first nozzle hole from the inside of the slurry supply pipe Pre-mixed in liquid state and is discharged to the outside through the exhaust hole slurry, coal slurry liquid state is activated by movement of the slurry is atomized outside the discharge hole by the secondary oxidant is injected through the nozzle assemblies to be pyrophoric characterized by the spread. ;
