Tiivistelmä
An experiment was conducted to investigate the energy consumed during extruder runs using an amorphous polymer (polyamide) of grade grimaldi TR 55, in the Arcada plastic laboratory. During this process, energy was applied to the polymer by the heating and the drive systems, this energy was used to melt and transport the polymer to the extruder die. The energy in the product will then be transferred to the water or air which is often discarded after the process.
The focus of this thesis is to quantify and qualify this stream of energy that is transferred in the cooling medium (air or water), by suggesting different methods which this energy can be valuable to the company. This energy may be extracted and converted in to different forms of energy (mechanical or electrical) using a heat exchanger, depend-ing on the quality and quantity of the heat content in the stream, or may be used directly in heating the surroundings.
