The temperature uniformity on radiant tube wall was effected by its combustion process.It is studied by the thermal simulation method.The result indicated that fullness degree of smoke in radiant tube was higher,the concentrated of high temperature region was diluted,NOx formation descended,convection heat transfer strengthened,and the tube wall temperature changes from 114~141℃.
