14.14. A three-stage evaporator is fed with
1.25 kg/s of a liquor which is concentrated
from 10 to 40 per cent solids by mass. The
heat transfer coefficients may be taken
as 3.1, 2.5 and 1.7 kW/m² K, respectively,
in each effect. Calculate the steam
flow at 170 kN/m² and the temperature
distribution in the three effects, if:
(a) the feed is at 294 K, and
(b) the feed is at 355 K.
Forward feed is used in each case and
the values of U are the same for the two
systems. The boiling point in the third
effect is 325 K and the liquor has no
boiling point rise.
