Description: General Information: Different possibilities have been studied to produce heat at 125 - 145 degrees c for a paper dryer from its waste heat at 80 - 90 degrees c. A comparison of the possible systems was made regarding technical feasibility, energy saving potential and costs. The two-staged absorption heat pump with libr/h2o was found to be able to work under the specific operating conditions of the reference paper machine. A 100 kw heat pump of this type was built and tested on a test rig. As a result of these tests the following modifications are being brought about: - installation of a pump to control the solution and avoid crystallization of libr - continuous measurement of the libr concentration - design of a new libr solution distribution system - replacement of the solution heat exchanger by a new apparatus with low losses.
