A psychrometric chart helps model the process. Stage 1 shows the inlet with the ambient moisture (amount of water vapor per unit of dry air) coming into the dryer. The cloud is small, reflecting the size and amount of water vapor present. In Stage 2, the air is heated to the inlet air temperature. The greater the amount of heated air from the ...

Spin Flash Drying is an industrial drying process used to remove moisture from liquid or pasty materials and transform them into a powdered form. The process involves introducing the material into a drying chamber equipped with a rotating disc or wheel. The rotation of the disc creates a fluidized bed where hot air is introduced, rapidly drying the material as …

Typically, the gross calori c value of natural gas is 54 000 kJ kg 1 and the net fi calori c value 47000 kJ kg 1. The latter is more convenient for calculations here, as fi the water generated by combustion ends up as water vapor. Hence 1 GJ heat is released from 21.3 kg fuel and generates 47.9 kg water vapor.
