Abstract

The overall objective of current research is to develop a high temperature solar heating system which generates 150°C of process heat for industrial purposes. Commercially available solar thermal systems can only achieve boiling temperature and is insufficient for industrial usage. Most common heat sources used in the industrial are the electrical boilers, diesel boilers, LPG boilers and waste burning boilers. All four boilers are considered as environmental unfriendly and produce greenhouse gases.  With increasing environmental consciousness in the community, more and more companies have begun to invest in renewable energy sources such as solar, hydro and wind. However, the high cost of investment for renewable energy is deterring the transition. Hence, new investigative research must be conducted to develop a more economically viable method to harness the renewable energy. In our case, the proposed system can achieve high temperature using cost effective solar collectors which will encourage the adoption of solar heating systems for industrial applications. A theoretical model to predict the system performance of the evacuated tube heat pipe solar collector would be developed. The theoretical model would enable an optimum system to be designed according to the varying solar radiation patterns and draw off requirements.

About the Speaker

Mr Tong Wei Li graduated with a 1st Class Hons in Mechanical Engineering from MUSC and was awarded with the best final year project award. He then continued his postgraduate studies in year 2010 under the supervision of Associate Professor  Ong Kok Seng. His research focuses on solar thermal energy utilization and heat pipe heat transfer. The present study aims to develop a high temperature solar water heating system for industrial applications.
