Why is it necessary to desuperheat steam? What types of desuperheater exist, where are they used, and how are they installed?

Basic types and more sophisticated types of desuperheater and their applications are discussed in some detail.


1. Basic Desuperheating Theory

Superheated steam has important advantages on certain applications, for example, when used in power stations to drive turbines. For efficient use on heating applications however, the steam must be desuperheated. This tutorial considers basic desuperheating theory and calculations.


2. Basic Desuperheater Types

This tutorial introduces the common types of desuperheater in regular use, their limitations and typical applications.


3. Other Types of Desuperheater

Additional desuperheater designs such as the venturi and variable orifice types are covered in this tutorial. A comparison of all types is included at the end.


4. Typical Installations

A number of important considerations need to be taken into account when installing desuperheaters. This tutorial covers issues such as water quality and pressure control. A desuperheater selection chart and a list of applications are also included.
