在设计的试验台上 ,进行了不同条件下的热风和过热蒸汽为干燥介质的对比试验 ,证明了过热蒸汽与热风干燥逆转点的存在 ,逆转点的温度值与理论分析有差别。过热蒸汽干燥应在超过逆转点的温度下进行。在较高的温度下进行干燥作业时 ,可采用废气循环的办法
On the designed test bench, comparative experiments on hot air and superheated steam under different conditions as drying medium were carried out. The existence of superheated steam and hot air drying reversal point was proved. The temperature of reversing point differed from the theoretical analysis. Superheated steam drying should be carried out at a temperature above the reversal point. When drying at higher temperatures, the exhaust gas recirculation can be used
