Abstract
A process for evaporation comprises the step of introducing high-temperature steam successively into separate bundles of horizontal heat-transfer tubes and spraying feed-liquid over the tubes. The number of the tubes in each bundle is smaller than that in the next lower bundle. The steam is first introduced into the tubes of the bottom bundle after cooled by subjection to condensate produced in the tubes of the middle bundle. An evaporator is also disclosed.
