Abstract: PVC waste is widely known as being a major environmental problem. The combustion process of this waste in circulating fluidized bed (CFB) is one of the most promising modern techniques. In this research, the hydrodynamics of PVC resin was studied in a cold flow CFB. Electrostatic effect of PVC causes particles to adhere to the inner column, preventing an observation of flow pattern during the test runs. Therefore, anti-static powder was added to reduce electrostatic effects in the system. The objective of this research was to investigate the flow pattern of PVC with and without anti-static powder. The cold flow CFB’s riser has a diameter of 5 cm and height of 200 cm. The mean diameter and density of PVC resin are 140 micron and 1,410 kg/m3, respectively. Superficial gas velocities used were in the range of 5.0-7.0 m/s. From the preliminary results, it was found that an addition of anti-static powder reduced electrostatic force between PVC particles and the riser column.
Description: The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
