Steam Generator VS. Steam Boiler. Steam and water vapour are actually the same. The term 'Steam' is used more along with the process application, whereas the term 'Vapour' or 'Vapor' is the theoretically used general term for gaseous matter generated from liquid (or solid) phase. Water and steam are often used as heat carriers in heating
Besides pool boiling, vapor is also generated by passing liquid through a tube heated either by firing fuel, as in a once-through boiler, or by condensing steam, as is commonly used in process industries. This method of generating vapor is known as forced-convection boiling. The nature of boiling in forced convection is similar to
