They are charging device and gas offtakes. These devices can ensure even distribution of the stock into the furnace and prevent loss of gas. 那是装料装置和煤气出口。这些装置可以保证炉料分布均匀,并防止煤气逸出。
Based on the existing calculation formulas, the uncertain factors in hydraulic calculation of flood drainage offtakes for small basin are analyzed, and the generalized resistances and generalized loads are analyzed and defined. 基于现有计算公式,分析了小流域排洪沟水力计算中的不确定因素,对设计中的广义抗力和广义荷载进行了分析和假定;
