The document provides an overview of mechanical vapor recompressor evaporators (MVRE), explaining that evaporators are devices used for reducing water content in fluids. It categorizes evaporators into natural circulation, forced circulation, and film evaporators, and describes different types of MVRE based on steam requirements. The document briefly touches on the thermodynamics and working principles of MVRE.

1. PRESENTATION ON MECHANICAL VAPOR
RECOMPRESSOR EVAPORATOR (MVRE)

2. What is Evaporator ???
• Equipments which are used for evaporation is called Evaporators.
• Evaporation means to reduce the water contents from fluid or thickening
of fluid.

3. Types of Evaporator ???
• Evaporators are mainly divided in three groups-
1. Natural Circulation Evaporator
a) Evaporating Pans
b) Evaporating Stills
c) Short Tube Evaporatorc) Short Tube Evaporator
2. Forced Circulation Evaporator
3. Film Evaporator
a) Wiped Film Evaporator
b) Long Tube Evaporator
c) Climbing Film Evaporator
d) Falling Film Evaporator

4. What is MVR ???
• MVR means Mechanical Vapor Recompressor i.e. type of
compressor which is used for increasing the latent heat or
temperature of steam.

5. Types of MVRE
• MVRE mainly divided into two groups-
1. With initial steam requirement
a) Film Type MVRE
b) Forced Circulation MVRE
2. Without initial steam requirement
a) Evaporating Pan with Extended Heat Transfer
Area MVRE
b) Evaporating Vessel Type MVRE

6. Thermodynamics of MVRE ???

7. Working of MVRE ???
