■ What is steam drain?   Steams used as heat source of drying process is condensed and changes its state into liquid after releasing its latent heat. At the time of changing state to liquid, it is hot water which have the same temperature as the steam. The hot water is called drain. Among heat […]

■ What is superheated steam Temperature of water does not rise for a while after the water is boiled and starts generating saturated steam. However, the temperature starts rising at some point. Condition of saturated steam can be distinguished as “wet saturated steam” and “dry saturated steam” more specifically. When steam contains water in it […]

■ Steam pressure Steam is generated when water is boiled though, there is a large difference between their volume. For example, volume of steam will be 1,700 times larger than water when steam is generated without adding pressure under atmospheric pressure. Boilers for creating steam generates steam by adding heat on water within sealed container. […]

■  Latent heat, sensible heat   Even heat keeps being added to saturated water, water temperature will not rise and water keeps boiling. Steam generated here is called saturated steam though, heat energy which make saturated water into saturated steam is called latent heat. Latent heat depends on pressure and it becomes lower as pressure […]

■  What is saturation temperature? When water in a container keeps being heated, its temperature rises and start boiling at some point, and the temperature stops rising. This water is called saturated water and the temperature is called saturation temperature or boiling point. Also, this saturation temperature depends on pressure. The pressure is called saturation […]
