specific Embodiment approach 1
[0006] Specific implementation mode one: (see Figure 1 ~ Figure 2 ) This embodiment includes burner primary air duct 1, concentration ring 2, support plate 3, inner swirler 4, inner secondary air duct 5, outer swirler 6, outer secondary air duct 7, burner 8. Support rod 9, third-stage combustion chamber 10, second-stage combustion chamber 11, first-stage combustion chamber 12, main oil gun 15, block 16, first air duct pipe 17, second air duct pipe 18 and The third air duct pipe 19, the primary air duct 1 of the burner is inside the first air duct pipe 17, the outlet end of the first air duct pipe 17 is the burner 8, and the support plate 3 is fixed at the entrance of the first air duct pipe 17 end, the concentration ring 2 is fixed on the support plate 3, the first-stage combustion chamber 12 and the second-stage combustion chamber 11 are fixed in the first air duct pipe 17, and the first-stage combustion chamber 12 is fixed on the support plate 3 front end, the second-stage...
specific Embodiment approach 2
[0007] Specific implementation mode two: (see Figure 1 ~ Figure 2 ) The difference between this embodiment and the specific embodiment one is that it increases the auxiliary oil gun 13, the auxiliary oil gun 13 is arranged in parallel with the main oil gun 15, the auxiliary oil gun 13 communicates with the first-stage combustion chamber 12, and the auxiliary oil gun 13 is connected with the first-stage combustion chamber 12. The outlet end of the gun 13 is arranged in the middle of the combustion chamber 12 of the first stage. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0008] Specific implementation mode three: (see Figure 1 ~ Figure 2 ) The difference between this embodiment and the specific embodiment two is that it has increased the flame detection device 14, and the flame detection device 14 is arranged between the auxiliary oil gun 13 and the main oil gun 15, and the flame detection device 14 and the first-stage combustion chamber 12 connected. Others are the same as in the second embodiment.
[0009] The pulverized coal is sent into the primary air duct 1 of the burner, and the pulverized coal is concentrated through the pulverized coal concentrator 2, and a high concentration of pulverized coal is formed in the central area of the primary air duct 1 of the burner. The 600MW subcritical boiler is calculated by fluent software Concentration distribution results such as ( image 3 As shown), the high concentration area of pulverized coal is in the center of the primary air duct 1 as the center of the 0.6R 0 Within, the rest is li...
