摘要
随着我国大容量燃煤机组地不断兴建,具有省材料、阻力低等优点的大截面圆形烟风道的应用逐渐增多。但是,国内电力设计规程中针对圆形烟风道的设计方法却已无法满足设计要求。因此,采用理论计算和ANSYS数值模拟结合的方式,对大截面烟风道的设计方法进行了研究,探索出一套切实可行的计算方法。
Newlarge capacity power plants in China recently are mainly coal fired plants. Because of lowmaterial cost,little resistance and others advantages,large cross-section circular duct application in newplants is becoming popular. At present,the design technique about circular duct is not applicable in many cases. A complete method of large cross-section circular duct design,which could be used in different cases of power plant,was developed in this article. And this method was verified by calculation results of ANSYS.
