AB - PROCESS STUDIES ANALYSIS OF THE OPERATION OF EVAPORATION EQUIPMENT WITH AN OUTBOARD BOILING ZONE S. L. Vorshchenko, S. I. Tkachenko, UDC 66.048.54 and I. I. Sagan' In recent years, evaporation equipment with intensified natural circulation and exten- sion of the boiling zone past the limits of the heat-exchange tubes has been finding increas- ingly wide application in industry. Such apparatus operate with lower, scale deposition and with greater heat-exchange intensity than apparatus with moderate circulation. The authors have developed an evaporation apparatus [i] in which, at the same length of the heated up and down tubes, there is a cyclindrical extension which encompasses half of the tube bundle. Under definite thermal and hydrodynamic calculated conditions the point of boil- ing is directly at the inlet of liquid into the extension. Test of the apparatus under fac- tory conditions have shown that it operates well. No deposits of scale were observed in evaporating wastes from alcohol manufacture at a concentration of 10%. However, the in- crease in length of the vertical heat-exchange tubes and of the heat stream leads to a de- crease in the coefficient of heat transfer from the steam to the tube walls, and, conse- quently, to
