Abstract
Combined heat and power (CHP) is considered one of the most appropriate and promising technologies for the improvement of industrial energy efficiency. This study is a feasibility analysis of the application of various cogeneration systems using biofuel (rice husk) based on Rankine, Brayton and Combined cycles for a medium-sized paper mill in Pakistan, to assess the potential for energy savings in this sector through improved energy efficiency. Thermodynamic and economic analysis are carried out to suggest the most appropriate option for the studied industrial unit. It was found that cogeneration based on the Brayton cycle is the most feasible option for the studied mill based on technical and economic perspectives, as it has the highest energy utilisation factor (EUF) and lowest annualised life cycle cost compared to the other proposed options. The overall saving of the proposed CHP system based on Brayton cycle is calculated at 2,515,216 USD annually. Keeping in view the energy crises in Pakistan, using energy efficient cogeneration systems and bio-fuel (rice husk) in the industrial sector, a significant amount of energy can be conserved, resulting in the reduction of GHGs and helping to achieve sustainability and a cleaner environment.
