Energy conservation is very important nowadays. For an optimized re-utilization of waste heat and heat from regenerative energy sources, an improved storage system with a minimum loss is required. Hydrophilic zeolites are suitable materials for this purpose. Currently they are used as packed beds. The main disadvantage of such packed beds is the high pressure loss for the flow of the heat transferring medium through such a bed. This reduces the efficiency of such a system clearly. Zeolitic honeycombs can overcome this problem. At the IKT these honeycombs are produced on a twin-screw extruder known from plastics engineering. In this way, two process steps (compounding and shaping) can be integrated into one step: The compound is mixed in the machine and directly extruded through an appropriate die. Such a compound of mineral based zeolitic honeycombs consists of zeolite, a binder, a plasticizer and water. The first three components can vary in type. To get good mechanical properties, green bodies of such a compound have to be heat treated after extrusion. As they are correlated to the wall thickness, capacity and kinetics of such honeycombs are adjustable. This makes it possible to adjust the honeycomb properties according to a wanted property profile. This enables the development of new highly efficient heat storage system that can be used for domestic heating, power-heat coupling systems or communal heat/power stations. [ABSTRACT FROM AUTHOR] |
