| Abstract: | This paper adoptes a numerical simulation method to analyze the fluid structure of a combustion chamber in supercharged boiler.Numerical results were analyzed in the combustion chamber and the main problems of the flow field were discussed.Special measures were taken to improve the flow structure inside the combustion chamber.Numerical experiments show that those measures are very effective and the modified design is much better than the original design. |
