Definition
A boiler is a closed vessel where water is heated to create steam. Think of it like a giant kettle, but for industrial purposes. The steam produced can power turbines, heating systems, or various manufacturing processes. Boilers are essential in power plants and many factories. Unlike a simple water heater, a boiler's steam has pressure, making it a potent energy source. Imagine it as the heart of a steam-powered machine, like the Millennium Falcon's engine.
