Energy conservation research in the paper and allied products industry. Phase 1

The Engineering Experiment Station of the Georgia Institute of Technology has conducted a study of certain concepts for energy conservation in the paper manufacturing industry. The primary emphasis of the study was evaluation of a textile industry device called a Machnozzle as an aid to dewatering of the press section felts. Experimental results indicate that significant reduction in felt moisture may be obtained by installing and operating the Machnozzle just prior to the suction box. Analysis of the economic and energy impact is hampered by lack of a clear understanding of the relationship between felt moisture and paper sheet moisture. Further study in this area is recommended. Also addressed in this project is the concept of maintaining higher feedstock temperatures, particularly through retention of thermal energy from the pulping process. Various problems relating to high temperature processing are discussed.
