Why is steam so important to many industries today, its powerful capabilities, and how this sustainable, natural energy source is generated today.

The science behind modern steam engineering introduced over 16 topics. These form a solid foundation for understanding the principles and practices relating to steam.

Key to the generation of steam is, of course, the boiler house. This section looks in detail at boilers themselves, issues like feedwater conditioning and water levels, and how the boiler house can best be run efficiently.

If you want to know exactly how much steam your processes are using, and how much they cost, flowmetering will play a pivotal role. This section details everything you'll need to know, from theory to techniques and practical applications.

How processes are controlled is fundamental to a safe, stable, and accurate system. In this section, we closely examine the theory behind control, why you might choose one option over another, and how to go about installing and commissioning control systems.

How control valves work, their correct sizing, and the role of actuators, positioners, controllers and sensors in steam and water systems.

Why self-acting controls are needed, the various options available, and their practical application in controlling temperature and pressure in steam and water systems.

This section discusses in detail the ways in which temperature, pressure, flow, and level are controlled in steam systems. We also look at why this is done, and the industries that use these controls.

This section answers the questions: what is a safety valve, what options are available, and how to choose the right one, and safely install it.

It's crucial your steam reaches the point of use in the most cost-effective, energy-efficient way possible. Sizing of pipes, key drainage techniques, how your piping is supported and deals with expansion, venting, and heat transfer calculations are dealt with in this section.

These 15 sections cover every aspect of steam traps: why are steam traps needed, how do steam traps work, what are the different types and where are they best used? We will also look at how to select the right steam trap, air venting, and why it is so important to maintain your steam traps.

Additional components are often left out of steam systems to reduce costs. This can be a false economy, since isolation valves, check valves, strainers, separators, gauges, sight glasses, and vacuum breakers are all important to an energy-efficient steam system.

Vital to the efficiency and long life of a heat exchanger, this section looks in detail at how they operate, what ‘stall’ is, and the best ways of maximising your efficiency.

Getting condensate back to the boiler house is key to sustainable operations. This section looks at pipe sizing and layout for drain lines, discharge lines, and pumped lines. Lift, backpressure, and the reduction of costs by using flash steam are also covered.

We examine what superheated steam is, and why it's sometimes necessary to desuperheat it. We also cover the types of desuperheater available, where they're used and how to install them.
