( 3 ) the result of imitating shows that the distribution of temperature look like triangle at present , the cause of temperature asymmetry is the mistake ratio of gas and air in the same vertical direction , the direction to improve on is by adjustment to distribute reasonably gas in different height and uniformly gas in same level ( 3 )仿真结果展现了目前铅塔燃烧室温度呈三角形分布，并揭示了造成这种不均匀分布的根本原因是空气、煤气在同一垂直方向的不匹配。并指出了改进方向是通过调整，使煤气2002年工程硕士毕业论文摘要在高度方向的名迢群引配、以及在水平方向均匀分布。
