脱硫塔渠道钢格栅板负载扁钢的距离和横杆的距离依据规划需求断定，作为工业渠道，负载扁钢的距离不大于40mm；在负载扁钢的端头，用与负载扁钢同标准的扁钢进行包边；在特别场合，用型钢或直接用挡边板包边，但包边板的截面积不得小于负载扁钢的截面积。
The distance of flat steel loaded on grille plate of desulfurization tower canal and the distance of cross bar are determined according to the planning requirements. As an industrial channel, the distance of flat steel loaded is not more than 40 mm; at the end of flat steel loaded, the flat steel with the same standard as the flat steel loaded is used to wrap the edge; in special occasions, the shape steel or the baffle plate is used to wrap the edge directly, but the wrap plate is used to wrap the edge. The cross-sectional area of the load flat steel shall not be less than that of the load flat steel.
