| description | The invention provides a stable combustion type combustor suitable for a tangential combustion boiler, and belongs to the field of combustors. The problems that a traditional low-nitrogen combustor is poor in rich-lean separation effect and unstable in combustion are solved. The pulverized coal burner comprises a primary air pulverized coal pipeline, a pulverized coal concentrator, a burner elbow, a primary air exhaust channel, a secondary air box, a secondary air channel, a primary air exhaust burner and a primary air main burner, the primary air pulverized coal pipeline is communicated with the primary air main burner through the burner elbow, and the pulverized coal concentrator is arranged in the primary air pulverized coal pipeline. The inlet end of the primary air exhaust channel is arranged in the burner elbow and right faces the outlet end of the pulverized coal concentrator, and the primary air exhaust burner and the primary air main burner are arranged in the secondary air channel in a vertically sp |
