Embodiment Construction
[0012] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0013] The fuel-saving / gas ignition and stable combustion low-nitrogen swirl pulverized coal burner of the present invention is mainly composed of an oil / gas burner 1, a primary air channel 2, a damper, an adjustment rod, a secondary air inlet pipe 8, and a secondary air flow in the swirl flow. The air inlet pipe 10, the secondary air inlet pipe 12 outside the swirl flow and the swirl flow blades are formed. The oil / gas burner 1 extends into the primary air channel 2, and the outer wall of the horizontal pipe section of the primary air channel 2 is provided with a guide sleeve that allows the oil / gas burner 1 to enter the primary air channel 2 and move back and forth. The axis line of the gas burner 1 coincides with the axis line of the horizontal pipe section of the primary air channel 2 . The outlet ends of the primary air channel 2, the secondary air in...
