Energy efficient internal material transport within industry
Results
The experiments carried out under the project shows that achieving considerable energy savings for industrial material transport through appropriate transport facilities, design and mode of operation. Air Supply in dilute-phase systems with low pressure (dp<1.0 bar) should be regulated by the frequency converter to increase the transmitting ported amount of material per. m3 of air. This typically produces electricity savings of 30-50 %.For materials that lend themselves to it, and where space and process permits, should be used dense-phase transport based on high pressure (dp>2.0 bar). It typically produces electricity savings of 50-70 %. The table shows the savings by changing dilute-phase to dense-phase transport of Polyethylene granules and Alginate.
Measurements at the Technological Institute and the test facility with Poul Andersen's Machinery has shown that very different materials can be transported pneumatically in dense-phase, and the optimal transport speed is identified through measurements.
The project has on this basis developed calculation program Dense Phase Calc, which can be downloaded from the project's specific information area of www.elforsk.dk under "Completed Projects" 334-032. The program makes it possible to find corresponding values in dense-phase systems transportrørets diameter and the associated air volume and pressure when the relevant material data and the desired transport length is known. In addition, the program calculates the energy consumption of the selected combination of these parameters. In this way the user can minimize power consumption by changing the parameters.
Measurements during the project's various experimental setups shows that its phase transport is about 30 % cheaper than dilute-phase, although dense-phase systems require significantly more investment than dilute-phase systems.
