In order to improve thermal efficiency,optimize the surface temperature uniformity of the surface of the radiation pipe,and reduce NOx emissions,the author designed a double-stroke-high-flue gas cycle of the W-type radiation tube to burn the mouth,and set up an experimental plat-form.The following conclusions:benefit the dual stroke tube-type heat exchange,the air preheating temperature of the air is above 500℃,and the preheating temperature can reach 755℃ when full load;The design of the design of the design can be rolled in a large amount As low as 13.34％,the maximum temperature difference between the surface of the radiation pipe is less than 120℃,and NOx emissions are less than 53×10-6.
