摘　　要：介绍了设置内筒的造纸机烘缸结构,其内筒筒壁上设置有均布的喷管,蒸汽通过喷管喷出冲击、扰动液环,提高传热效率,并进行了实验验证。计算出了内筒蒸汽的供给压力和温度,设计计算了喷管的相关参数。The structure of the dryer for paper machines equipped with internal cylinder was introduced, in which the nozzles were uniformly distributed on the internal cylinder shell. The steam was spurted from the nozzles and water ring was stroked and perturbed to increase heat transfer efficiency. All of these were testified through experiment. Besides, the supply pressure and temperature of the internal cylinder steam were worked out; the relevant parameters of the nozzles were designed and calculated.
