Steam Theory for Tissue Machines
Steam is commonly used in industrial environments for power generation and in heating and drying applications. On a tissue machine, steam is used to dry the sheet of paper to a target moisture content before it is wound up on large rolls that can be transported, stored and shipped. Before one can understand how steam is used in heating and drying applications, like tissue machine drying systems, it is important to understand how steam is created, how heat energy is transferred from the steam to the sheet of tissue, and the relationship between steam pressure and steam temperature.

Sample Video Transcript
Steam is used in many different places and in many different ways. In industrial environments, it is commonly used for power generation, and in heating and drying applications. This module will focus on steam theory as it relates to heating and drying. Though this information is also relevant to the generation of power. We will use a tissue machine drying system as an example. Steam is used on a tissue machine to dry the sheet of tissue to a target moisture content. Before one can understand how steam is used in this type of process, it is important to first understand how steam is created, how heat energy is transferred from the steam to the sheet of tissue, and the relationship between steam pressure and steam temperature.
