WAERMEPUMPEN ZUR WAERMERUECKGEWINNUNG AUS PAPIERTROCKNUNGSMASCHINEN - ERZEUGUNG VON PROZESSDAMPF AUS DER TROCKNERABLUFT.
Different possibilities have been studied to produce heat at 125-145 degrees for a paper dryer from its waste heat at 80-90 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/H-2O 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.
