What is a Boiler?
A boiler is a huge device in a form of a closed container that is capable of heating different fluids especially water. The heated fluid is expelled by the blower to be used in other things or processes that required that fluid. In some instances, the fluid heated inside the boiler goes out of it in the form of steam or water vapor because there are certain processes that require such.
Usually, boilers are made of high quality stainless steel to be able to hold fluid without oxidation or rusting. High quality material is required so that it can handle high heat and high pressure where processing the temperature of different fluids.
When wood or natural gas boilers
are heated up, they use the combustion process in order to transfer heat from the device to the fluid inside it. Usually, the boiler uses oil, gas or wood as fuel source in its combustion process. Other types of boilers use nuclear fission to generate steam or the power rejected by turbines to produce heat for the fluid inside the vessel.
