Heat Exchanger and Boilers – Energy Conversion Guide

Overview

This lecture deals with the practical use and applications of heat exchangers and boilers. These two appliances have much in common, since heat exchangers are vital parts of boilers, and in addition, boilers are the oldest and still one of the most common applications of industrial heat exchangers.

These two devices will be discussed separately, although. After an exposition of all different types of heat exchangers and examples of their usage, an overview about what has to be dealt with when one of these types needs to be installed and how to maintain it, will follow. After this, the same will be done for boilers.

Heat Exchangers

Heat exchangers can be described by reversing it’s two terms: they include all devices that are designed for exchanging heat. This is a very broad category of devices so first a restriction has to be made. Only heat exchangers that are meant to exchange heat between two fluids are taken into account. These fluids can be gasses as well as liquids.

It is still difficult to have an overview, and a classification needs to be made. It is possible to classify heat exchangers in a number of ways.
