A Forward Feed Triple Effect Evaporator Where Each Effect Has 150 M Of Heating Surface Is Used To Concentrate A Soluti 1 (44.16 KiB) Viewed 18 times
Can you please give me the answer.. but using heat transfer calculation method. I have posted this question twice..but the calculation is not what i need..so please provide me the correct calculation..
A forward feed triple effect evaporator, where each effect has 150 m² of heating surface is used to concentrate a solution containing 5% solids to a final concentration of 30% solids. Steam is available at 97 kPa (gauge), and the boiling point at the last effect is 40 °C, The overall heat transfer coefficients, U in W/m² °C are 2900 in effect 1, 2600 in effect 2 and 1300 in effect 3. The feed enters the evaporator at 90 °C. Calculate the flow rate of feed and the steam consumption. Assume boiling point elevation is negligible.
