ABOUT THE STATE OF COMBINED HEAT AND POWE R, MULTIPLE-USE OF ENERGY AND EVAPORATOR TECHNOLOGY .2.

In the sphere of multiple use of energy there will be a report on evap orator technology in the western and eastern German factories of Sudzu cker. Low steam consumption pre-supposes new technology, heating schem es, increase in number of effects or transition to thermocompression. The evaporators built and planned as well as their optimization will b e described. In this the technological and economic use and the limita tions of individual designs such as natural circulation, falling film and plate evaporators and their composite action in the system will be considered. Initially the subject will be operational experience with the plate evaporator.
