METHOD OF BOILING-DOWN ALUMINATE SOLUTION

摘要

FIELD: boiling-down crystallizing solutions; production of alumina. ^ SUBSTANCE: proposed method of boiling-down the aluminate solution is performed in evaporator working on natural circulation of solution at discharge of solution from heating (heat exchange) tubes to special chamber where injection of circulating solution is created similarly as in jet apparatus for increase of rate of its motion in heating tubes. ^ EFFECT: enhanced efficiency due to increased degree of circulation of solution through heating tubes at boiling of solution outside heating tubes. ^ 2 dwg
