Steam Boiler VS Steam Generator

Data shows that steam is the very very necessary energy in many industries like chemical industry, paper & pulp, food & beverage, hotel, hospital, textile plant, steel & iron industry, power plant, etc. Any way steam really has a wide application. Steam boilers and steam generators are the equipment to supply the needed steam, and what are the differences between steam boilers and steam generators?

Steam Boiler VS Steam Generator
As you might be aware, today steam in boilers/steam generators can be generated at sub-critical/super-critical water pressures. When water is turned into steam by boiling at sub-critical pressures, the steam-generating equipment is called a "steam boiler" When water turns into steam without boiling at super-critical pressures, the equipment is called "steam generator".

In short,
Sub-critical Steam generators = Steam Boilers
Super-critical Steam generators = Steam Generators

Besides, a steam boiler is exactly what the name implies. The steam is made by the water reaching boiling point. However, this isn't always the case for a generator. The water doesn't necessarily need to reach boiling point in order to produce steam. These can be much safer as well since they don't reach as high of a temperature.
