specific Embodiment approach 1
[0025] Specific implementation mode one: combine figure 2 and Figure 4To illustrate this embodiment, this embodiment arranges the exhaust gas front W flame boiler with the secondary air nozzle on the arch, which includes the upper furnace 1, the lower furnace 2, the front furnace arch 3 and the rear furnace arch 4, the upper furnace 1, the front furnace Furnace arch 3, lower hearth 2 and rear furnace arch 4 constitute the furnace body, which also includes two rows of double cyclone thick and thin pulverized coal burners 5, and each row of double cyclone thick and thin pulverized coal burners 5 includes multiple double cyclone thick and thin coal Pulverized coal burner 5, a plurality of thick and thin pulverized coal burners 5 with double cyclones are symmetrically arranged in a line and installed on the front furnace arch 3 and the rear furnace arch 4, and the double cyclone thick and thin pulverized coal burners 5 include exhaust gas nozzles 6, The secondary air nozzle 7 o...
specific Embodiment approach 2
[0026] Specific implementation mode two: combination Figure 4 To illustrate this embodiment, the cross-section of the exhaust gas nozzle 6 in this embodiment is circular, and the area of the exhaust gas nozzle 6 is equal to the cross-sectional area of a single exhaust gas pipeline on the double-cyclone thick-lean pulverized coal burner 5 .
[0027] Other compositions and connections are the same as in the first embodiment.
specific Embodiment approach 3
[0028] Specific implementation mode three: combination Figure 4 To illustrate this embodiment, in this embodiment, along the depth direction of the furnace, the dense pulverized coal airflow nozzles 9 and exhaust gas nozzles 6 of each row of double cyclone thick and thin pulverized coal burners 5 are arranged on the same straight line, along the width direction of the furnace. The exhaust gas nozzle 6 on each double-cyclone thick and thin pulverized coal burner 5 is arranged in the center of the corresponding two dense pulverized coal gas flow nozzles 9 .
[0029] Other compositions and connections are the same as those in the second embodiment.
