Water is a useful and cheap medium for transferring heat to the process. Boilers are fuel-burning appliances that provide a means for generating hot water or steam under pressure, which is then usable for transferring heat to the process or used as a hydronic heating system for large buildings.

There are virtually an infinite number of boiler designs, but generally they fit into one of the two categories; (1) Fire-tube boilers or as an easy way to remember “fire in tube boilers”, which contain long steel tubes through which hot gases from a furnace pass and around which the water to be changed to steam circulates and (2) Water-tube boilers or “water in tube boilers” in which the conditions are reversed with the water passing through the tubes and the furnace for the hot gases surround the water tubes.

When water is boiled into steam, its volume increases about 1600 times, producing a force that is almost as explosive as gunpowder. Proper design, selection, maintenance and operation of a boiler system is therefore important with regard to efficiency and reliability. Without this attention, boilers can be extremely dangerous and hence must be treated with the utmost respect.

This 3-hour course covers the fundamentals of steam and hot water boiler types, design, operation, and how the components of a steam generation plant interrelate.
