Abstract : apply computer simulation to the distribution pattern of air - flow without considering the cold condition of the combustion and compare the flow patterns under different designed circumstances. and the effect of the design of the partition in the air way of the burner on the flow and mixture of gas and air is especially studied. the result shows that the design of partition plays a very important role in strengthening the mixture of gas and air, but increases the loss of the resistance in the air way and the total pressure of the air way in same working conditions needs increasing
