How do heat exchangers work? - Explain that Stuff
H ave you ever watched wisps of smoke drifting from smokestacks and wondered how much energy they're uselessly pumping into the air? Maybe less than you might think! Saving energy is a huge and costly problem for factory bosses and it's one reason they often install devices called heat exchangers to salvage as much heat as possible from waste gases. . Heat exchangers have lots of other

Steam Boiler Types, Construction and Working …
What is a steam boiler? A boiler or a steam boiler in simple words is a device used to generate the steam at a desired pressure and temperature by transferring heat energy which is generally produced by burning fuel in order heat the water to change it to steam. The steam used in the boiler is used for external purposes i.e. electricity generation, heating or other industrial purposes.
