Improvements in Evaporators

Many improvements have been made in evaporator technology in the last half-century. The improvements have taken many forms but have served to effect the following:

1. Greater evaporation capacity through better understanding of the heat transfer mechanisms.
2. Better economy through more efficient use of evaporator types
3. Longer cycles between cleaning because of better understanding of salting, scaling, and fouling.
4. Cheaper unit costs by modern fabrication techniques and larger unit size.
5. Lower maintenance costs and improved product quality by use of better materials of construction as a result of better understanding of corrosion.
6. More logical application of evaporator types to specific services.
7. Better understanding and application of control techniques and improved instrumentation has resulted in improved product quality and reduced energy consumption.
8. Greater efficiency resulting from enhanced heat transfer surfaces and better energy economy.
9. Compressor technology and availability has permitted the application of mechanical vapor compression.
