Economy of a multiple effect evaporator depends upon the _____________________?
Correct answer: A. Heat balance consideration
- A. Heat balance consideration
- B. Rate of heat transfer
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
Evaporator economy is determined primarily from the heat and mass balance, especially how the vapour generated in one effect supplies heat to the next. The heat-transfer rate mainly controls capacity or throughput rather than the basic economy.
