摘　　要：[目的]为简化传统电厂汽机房自然进风、自然排风中和面选取及百叶面积计算方法,进一步揭示中和面与进排风口总面积及经济性关系,以某垃圾焚烧发电厂汽机房为工程案例进行分析,以中和面法对不同百叶高度、进排风口面积及造价进行计算。[方法]采用Python编程语言对繁杂的试算过程进行编码计算。[结果]结果表明:在充分考虑汽机房夹层、运转层楼板散热前提下,选取100%底部进风和60%-40%进风模式有较好的经济性,无论哪种进风模式,中和面高度选取按运转层+3~9 m范围,进排风总面积和总造价波动范围较小。[结论]实际工程中可按此方法选取中和面高度及进、排风百叶面积。[Introduction]In order to simplify the neutral surface method selection and the calculation method of the area of louvers for the natural ventilation of the steam turbine rooms of the traditional power plants,to further reveal the relationship between the neutral surface and the total area of the air inlet and outlet as well as the economy,a steam turbine room of a waste incineration power plant is analyzed as an engineering case.The different louver heights,the area of the air inlet and outlet and the cost are calculated by the neutral surface method.[Method]The Python programming was used to calculate the complicated trial calculation process.[Result]The results demonstrate that under the premise of fully considering the heat dissipation of the mezzanine floor and the operating floor of the steam turbine room,100%bottom air inlet and 60%-40%air inlet mode are more economical.No matter which air inlet modes,the neutral surface height is selected according to the operating floor+3~9 m range,and the fluctuation of the total area and cost of air inlet and outlet are small.[Conclusion]The neutral surface and the area of the air inlet and outlet louvers of actual projects can be selected by using this method.
