在《石油库设计规范》(GBJ74-84)中规定:浮顶油罐的燃烧面积,应按罐壁与泡沫堰板之间的环形面积计算。泡沫堰板距罐壁应为1.2～1.4m,浮顶 油罐的堰板高度,当采用机械密封时不应小于0.25m;当采用软密封时不应小于0.9m。为此,目前大多数软密封浮顶油罐泡沫堰板的设计均按图1的形式,将堰板设计成一圈等高的挡板。 In the “Design Code for Oil Depot” (GBJ74-84), the burning area of ​​a floating roof tank shall be calculated according to the annular area between the tank wall and the foam weir. Foam weir plate from the tank wall should be 1.2 ~ 1.4m, floating roof tank weir plate height, when the mechanical seal should not be less than 0.25m; when the soft seal should not be less than 0.9m. For this reason, at present, most of the designs of the soft-sealed floating roof tank foam weir are in the form of FIG. 1, and the weir boards are designed into a circle of baffle plates of the same height.
