Development and Characterization of Paraffin Wax Based Phase Change Material with Blacksmith Slag Snag

Abstract:

Rapid growth in population has resulted in increased use of fossil fuels to meet the increasing energy demands. This has negative effects on the environment and poses a question about meeting the future energy demands as the fuel reserves are limited. The development of renewable energy sources is at the peak to nullify the negative impact of fossil fuels. The intermittent nature of solar energy has attracted the development and testing of latent heat storage systems (LHS). This work aims to develop a phase change material (PCM) with paraffin wax and slag snag (a byproduct of blacksmith). A few characterization methods were applied on the prepared samples to observe the effect of slag particles on the paraffin wax like, XRD, FTIR, DSC. XRD and FTIR results show good compatibility among the constituents. DSC results show 4% and 2% changes in latent heat capacity of heating and solidification as compared to pure paraffin. The FTIR and DSC analysis after 100 number of thermal cycles with the developed composite show that the composite is thermally reliable. This low cost, environment friendly and easy to prepare PCM with slag particles is not only a promising candidate for medium temperature applications abut also keeps in check the recyclability or reusability of wastes like metal slag.
