We get it: industrial boilers are massive, complex pieces of equipment and it can take a lot of time to develop an understanding of how they work. The team at Manley’s Boiler is here to give you a primer on the basics of your industrial boiler. Here’s what you need to know to start—though, of course, we are always available for additional questions. Simply give us a call!
Boiler Construction 101
Industrial boilers are welded from sturdy steel plates that are engineered to withstand intense heat and pressure—as a result of this thick steel, boilers can sometimes weigh as much as 165 tons! The construction of hot water boilers and steam boilers is very similar. They both feature a cylinder tube, otherwise known as the pressure vessel. The pressure vessel contains something called a flame tube, which is fired through a burner and a reversing chamber that feeds flue gases back through a second smoke tube. These flue gases are reversed again via an external reversing chamber. This reversing chamber sends the flue gases to the end of the boiler, in the third smoke tube pass. A major difference between hot water industrial boilers and the steam versions? Hot water boilers, as their name implies, are usually completely filled with hot water during their operation, while steam boilers are filled with water only until the ¾ mark, with the top fourth of the boiler reserved for steam.
How Industrial Boilers Work
All boilers, whether hot water or steam, depend on fuel to run. The heating process is initiated when the burner heats or evaporates the water inside it, which is ultimately transported via pipe systems. Hot water boilers rely on pumps to move the heat through the system, while steam boilers are transported with the pressure generated in the heating process. Eventually, cooled water or condensed steam is returned back through the pipes to the boiler system so that it can be heated once again. While the boiler is generating energy in the form of heat, flue gases, a byproduct of this process, are removed through a chimney system—which is why regulating the emissions of industrial boilers is taken very seriously.
