Condensation heat transfer and convective heat transfer -2 The last continuance The following is specific example of how the heat is transferred. First of all, heat transfer during indirect heating using highly-heated oil or heated water will be explained. There is no phase transition in these heating mediums. They are heating by sensible heat. They give their […]

Condensation heat transfer and convective heat transfer -1 It is often said that steam is the best heat source for indirect heating which heats object via heating medium. There are other mediums of indirect heating such as oil and hot water. Compering with other mediums of indirect heating, steam is better in the following two […]

About Critical point First of all, the term of “critical point” is a physics term, however, it is often seen in other fields as well. A fluid exceeding the critical point is called supercritical fluid and it is called supercritical water in case of water. So, what is a “critical point”?To put it simply, it […]

About the condition of steam Condition of steam can be divided into wet steam and superheated steam briefly. When water is heated under a certain pressure, its temperature stops rising and the water starts boiling. The temperature at this point is called “saturation temperature” and the water at this point has been named as “saturated […]

What is heat source / steam of dryer? What is “steam” precisely? Normally in many factories, steam is generated by steam generators or by boilers and used for various purposes.Steam is one of gaseous substances. The gaseous substance is roughly divided into steam and gas. When the substance is distincted between steam and gas, the […]
