What is the Evaporator economy of the 1st effect if we evaporate 10kg/hr of water from a feed of 50kg/hr at a temperature of 25<sup>o</sup>C to a final temperature of 100<sup>o</sup>C in an hour in a triple effect forward feed evaporator which has steam supply of 25kg/hr? Given the concentration changes from a value of 0.3 to 0.55 in the 1st effect of the setup.<br>Latent heat of vaporization of water = 2,260 kJ/kg
We have a triple effect evaporator which has steam supply of 5kg/hr, the setup is a forward pass setup, the feed enters the 1st setup at 10kg/hr of 50% concentration and leaves the final effect at 75% concentration. What is the economy of this setup?
Which type of feeding is supposed to give maximum economy to a particular consumption?
The formula for the economy of the evaporator does not depend on the type of feeding.
We have a triple effect evaporator which has steam supply of 5kg/hr, the setup is a forward pass setup, feed enters the 1st setup at 10kg/hr of 50% concentration and leaves the final effect at 75% concentration. What is the product discharged from this setup?
We have a triple effect evaporator which has steam supply of 5kg/hr, the setup is a forward pass setup, feed enters the 1st setup at 10kg/hr of 50% concentration and leaves the final effect at 75% concentration. What is the evaporate discharged if the total evaporate from 1st and 2nd effect are 2kg/hr and 1kg/hr respectively?
