Amatrol’s Steam Systems 1 Learning System (950-SH1) introduces learners to the operation, installation, maintenance, and repair of steam systems and their application in paper mills, commercial and residential settings, power companies, and even nuclear submarines. Amatrol’s exceptionally thorough curriculum covers a comprehensive range of steam system topics, including both practical applications such as how to operate a boiler and theoretical knowledge like the coefficient of volume and thermal expansion.

The 950-SH1 includes an electric boiler, blowdown separator, condensate feedwater system, heat exchanger, strainer, and steam trap. This learning system also comes with a welded steel mobile workstation (32-in W x 82-in H x 92- in L) with 4” square welded steel tubing and heavy duty casters. Amatrol supplies these industrial-grade, top-flight components in order to give the learner an opportunity to work with real-world mechanisms and gain experience they would normally only acquire on the job.

The 950-SH1 explains important concepts like internal energy, specific heat capacity, and flash steam, as well as important calculation for steam power, such as calculating the change in enthalpy caused by phase change. Learners can then see how this theoretical material applies to tasks like the startup, shutdown, and blowdown of a boiler; the operation of an OS&Y valve; and how to test a steam trap.

Steam Safety Precautions

Amatrol’s 950-SH1 also provides learners with a thorough understanding of the dangers of working with steam systems and the safety precautions that can prevent injury. The 950-SH1’s curriculum teaches ten basic safety rules for working around steam systems, such as the appropriate choice in clothing to avoid burns, what safety components are present on a steam system, and the dangers of opening and closing valves without knowing their function. The 950-SH1 also covers maximum allowable working pressure (MAWP) and how safety relief gauges can keep a user safe when pressure builds in a steam system.

Thermal Science Learning System (T7081)

Amatrol’s Thermal Science Learning System (T7081) provides learners with the knowledge and equipment needed to comprehend the principles of modern thermal systems, such as HVAC, geothermal, refrigeration, and steam systems. As learners progress through the curriculum, they will perform experiments demonstrating principles such as the ideal gas law, linear and volumetric thermal expansion, basic temperature measurement, latent and sensible heat, specific heat capacity, conduction, convention, radiation, evaporative cooling, and basic refrigeration.

This tabletop learning system showcases a full range of components, such as a fi re syringe, a vacuum hand pump, bi-metallic ball and ring, and many more on a vertical panel for easy access and inventory. These components are used in various combinations to conduct experiments that show learners physical examples of thermal concepts and build foundational knowledge that they can use in real-world applications!

Hands-On Skills to Reinforce Theoretical Knowledge

The best way to engage learners and reinforce theoretical concepts is to apply the concept using hands-on skills. For example, using a vacuum pump supplied with the T7081, learners lower the pressure on a container of warm water until it boils, which demonstrates the relationship between pressure and a fluid’s boiling point. As learners study thermal expansion, a key concept in bimetallic thermostats, they will apply heat to a bimetallic strip and observe how different metals expand at different rates. These and many other experiments engage the learner and build a solid foundation for further study in the field of thermal systems.
