Famous mathematician Hero, also known as Heron was probably the first one to come with a simple steam engine. Hero from Alexandria, also wrote three books on mechanics and properties of air. This dates back to AD. 75.
Steam is largely used for the purpose of process heating. Using steam for processing heating offers multiple benefits over other heating media. Numerous benefits, simplicity of the system and high efficiency and reliability make steam the first choice for process heating.
Saturated steam is the steam which is completely dry and has same temperature as the water from which it is formed. When we start boiling the water, its temperature goes on increasing till it reaches the boiling point at that pressure.
This article elaborates on different grades of steam and characteristics of each of them.
Clean steam is defined as steam which is free of all kinds of contaminants. There are many different substances, which may be considered as contaminants; in general, they can be classified into four groups
Steam quality plays an important role in determining the quality of final product. At the same time, steam quality is also important to ensure smooth working of the plant and operational efficiency.
Flash steam is produced when high pressure condensate is discharged to a lower pressure. The word 'flash' describes the way it is formed. At atmospheric pressure, water boils at 100 Deg. C.
