Problems solved by technology
[0003] The present invention provides a high-strength gasification furnace process burner, which mainly solves the problem in the prior art that the outlet of the central oxygen pipe of the burner is a straight tube type, so that the speed of injecting the central oxygen is relatively slow, and the coal slurry and The premixing efficiency of oxygen is low, and the use of jacketed cooling pipes makes the cooling effect poor and other technical problems

Embodiment
[0023] Embodiment: a kind of high-strength gasifier process burner of this example, as figure 1 , figure 2 , image 3, including an outer pipe 1, one end of the outer pipe is connected with a nozzle mechanism through a flange, and a cooling water coil 3 is wound around the nozzle mechanism. The cooling water coil is made of Inconel600 high temperature resistant material, and the temperature of the cooling water in the cooling water coil is 160-200°C. The nozzle mechanism includes a primary oxygen nozzle 4, and a coal slurry nozzle 5 is arranged in the primary oxygen nozzle. The coal slurry nozzle is made of GH188 and UMCo-50 wear-resistant materials, and the outer surface of the coal slurry nozzle is coated with a ceramic layer. There is a gap between the primary oxygen nozzle and the coal slurry nozzle to allow oxygen to pass through, and a secondary oxygen nozzle 6 is provided in the coal slurry nozzle, and a gap is provided between the coal slurry nozzle and the secondar...

The invention relates to a burner and in particular relates to a high-strength gasifier process burner. The technical problems that the speed of injecting central oxygen is low and the efficiency of premixing coal slurry and oxygen is low caused by the factor that an outlet of a central oxygen tube of the burner is in a straight tube mode, a cooling effect is bad by employing a jacket type cooling tube, and the like in the prior art are mainly solved. The high-strength gasifier process burner comprises an outer pipe, wherein one end of the outer pipe is connected with a nozzle mechanism through a flange; a cooling water coil pipe is wound outside the nozzle mechanism; the nozzle mechanism comprises a primary oxygen nozzle; a coal slurry nozzle is arranged in the primary oxygen nozzle; a secondary oxygen nozzle is arranged in the coal slurry nozzle; a certain retraction amount is formed from the end face of the secondary oxygen nozzle to the reference surface of the end face of the burner; the ends of the primary oxygen nozzle, the coal slurry nozzle and the secondary oxygen nozzle are in a necking mode; the primary oxygen nozzle, the coal slurry nozzle and the secondary oxygen nozzle are communicated with a primary oxygen inlet, a coal slurry inlet and a secondary oxygen inlet respectively through a pipeline mechanism.
Description
technical field [0001] The invention relates to a burner, in particular to a high-strength gasification furnace process burner. Background technique [0002] The structure of the process burner is changed to three concentric channels, two channels, outer oxygen pipe, coal slurry pipe, central oxygen pipe, and cooling water pipe. A Chinese patent discloses a coal-water slurry burner (publication number: CN103013574 A), which includes a fuel gas pipe with a fuel gas passage inside the fuel gas passage, and an ignition mechanism inside the fuel gas passage; the first oxygen pipe, the first oxygen pipe Sleeved on the outside of the fuel gas pipe to define a ring-shaped first oxygen passage between the first oxygen pipe and the fuel gas pipe; the coal-water slurry pipe, the coal-water slurry pipe is sleeved on the outside of the first oxygen pipe to in the coal-water slurry An annular coal-water slurry passage is defined between the pipe and the first oxygen pipe; the second oxy...
