| Abstract: | This article describes the arrangement of the burners and the structure characteristics of the single burner of the 800MW boiler combustion system in Suizhong Power Plant.Tests on air dynamical field of this burner model are finished by heat thread anemoscope. These determine the proportion of central wind to second wind and the angle of second wind vane. All of these ensure the process of burning safe and steady. Laws of influence to the flow field caused by the adjustment of every layer wind are studied .Numerical simulation of air dynamical field of single burner is made. The results of the tests and simulation can provide standards of design, running and reform for high-parameters and huge-capacity boiler in our country. |
