Berlin www dampfundkondensat de steam and condensate for papermachines e e. A scheme of a simple open conventional steam condensate system is given in figure 5 6 the steam produced in the boiler house is transported via pipelines to the heat consumers heat exchangers.

The first and the last sections of the paper machine usually operate in conditions of vacuum. Past the press section the paper sheet has a water content of about 60. Heat apparatus where the steam condenses. In the dryer section the moisture is evaporated as the sheet is pressed between a fabric and the hot drying cylinder.

An alternative scheme of a cascade steam condensate system with ejector thermocompression suitable for application in paper machines is given in figure 5 10. 3 1 introduction steam has been a popular mode of conveying energy since the industrial. This is achieved by means of several steam heated dryers cylinders. The objective of the steam and condensate system in the paper machine is to provide the steam for the drying.

The final drying is achieved in the drying section. At the exit of the heat exchangers condensate batteries. The paper sheet runs over a large number of.
