Abstract

The invention provides a sandwich wind combustion device and solves the problem that a brown coal boiler combustor is low in performance due to the fact a brown coal boiler combustor is simple in structure in the prior art. The sandwich wind combustion device comprises a first passage, a second passage, a wind powder inlet, a wind blowing inlet, a wind powder spraying port, N wind spraying ports, a sandwich wind passage and a sandwich wind spraying port, wherein N is a positive integer larger than 1. The second passage is arranged in the first passage. The wind powder inlet is arranged at one end of the second passage. The wind blowing inlet is arranged at one end of the first passage. The wind powder spraying port is communicated with the second passage. The wind spraying ports are communicated with the first passage. The sandwich wind passage is arranged between optional two adjacent wind spraying ports. The sandwich wind spraying port is arranged at one end of the sandwich wind passage and used for discharging sandwich winds to a boiler combustion chamber. The wind powder spraying port, the wind spraying ports and the sandwich wind port are all communicated with the boiler combustion chamber. By the sandwich wind combustion device, performance of the brown coal boiler combustor is improved.

Description

technical field [0001] The invention relates to the field of burners, in particular to a sandwich air combustion device. Background technique [0002] With the diversification of domestic and foreign power coal, more and more boilers are burning lignite, which requires high-efficiency burners to continuously develop burners suitable for this coal quality. The lignite boiler burner in the prior art has the problems of poor combustion stability, coking at the nozzle, inability to burn out, and high nitrogen oxide emissions due to its simple structure. Therefore, a lignite boiler burner with high combustion performance is urgently needed. Contents of the invention [0003] The invention proposes a sandwich air combustion device, which solves the problem of low performance of a lignite boiler burner due to a simple structure in the prior art. [0004] Technical scheme of the present invention is realized like this: [0005] A sandwich air combustion device, comprising: [0...
