| 摘要 | The object of the invention is a pulp dryer's end wall (1), which comprises an upper edge and a lower edge, the distance between which edges defines the height of the end wall. An opening (51)for introducing the pulp web inside the pulp dryer or for bringing the web out of the pulp dryer is arranged between the upper and lower edges. One or more openable end wall elements (2, 21) for observing the inner parts of the pulp dryer and for performing maintenance operations is arranged between the upper and lower edges, the end wall element (2, 21 ) being arrangeable to a closed and an open position in order to cover or to expose a turn roll (7,71) located in the inner part of the pulp dryer. The height of the openable end wall element is at least 50% of the distance between the axes of two turn rolls (7,71) of the pulp dryer that are one above the other and exposed in the open position. An object of the invention is also a pulp dryer and a method for observing the inner parts of the pulp dryer. | ||||||
