What is a Boiler and How Does it Work? - RealPars

Aug 19, 2019 · Steam boilers generate steam in order to power turbines for power generation and various other industrial heating applications. To visualize the effects of steam generation using a boiler, think of the steam powering a turbine. When the steam passes through the blades of a turbine, the force turns the blades and accelerates the turbine.
