Steam Condensate - an overview ScienceDirect Topi

The simplest design used on older machines is the basic steam and condensate control system, which supplies steam at controlled pressure and removes condensate for reuse in the steam plant. The cascade steam system is slightly more complex and is useful for a system using high and low pressure dryers.
