Abstract
In this paper, three dimensional numerical simulation of cold flow field were conducted for W-shape flame boiler furnace. The initial data of flow field for numerical simulation were given with the method of one-dimensional flow instead of the artificial method, that had been widened the useful region of the code. Morever the method of the correction of the section continuity at the place of the outlet and the nose of the furnace was adopted, it leads to the velocity of the convergence had been accerlerated. The compute data had been compared with the experiment data from model test, the results stated : the compute data were good in accordance with the experiment data. The results in the paper may be used to enhance the understanding of flow process in the real W-shape boiler furnace.
