Comparative Analysis of Heat Transfer Coefficient for Wood and Non-wood Pulp Fiber: A Recent Study

A close loop circular pipe heat exchanger was used to compare the heat transfer coefficients of Acacia Mangium (wood) and Kenaf bast (non-wood) pulp fibre suspensions. The magnitude of the heat transfer coefficient was shown to be strongly impacted by parameters such as fibre type, pulp concentration, features, and fibre pulping method during the test investigation. Heat transfer coefficients were found to be higher than those of water at low fibre suspension concentrations and greater flow rates; however, heat transfer coefficients were found to be lower at higher concentrations and lower pulp suspension. It was discovered that as the fibre flexibility of Acacia Mangium and Kenaf bast increases, the values of heat transfer coefficient drop. Fiber size and flexibility, as well as heat transfer coefficient values for both wood and non-wood fibre suspensions, are all interrelated in this study. Fiber quality can be increased by altering fibre pulp properties for the creation of specialised products by using correct fibre pulping methods.
