gases has proven to be an efficient source of energy generation.
This study investigates the potential of utilizing exhaust air from ducts in industrial or ventilation systems as a resource for wind turbine energy generation. The proposed system incorporates specially designed turbines strategically placed within the ducts to capture the kinetic energy of the moving air. Through computational simulations and experimental validations, this research aims to analyse the feasibility, efficiency, and environmental impact of harnessing this exhaust air as an additional renewable energy source. The findings from this study offer insights into a novel approach for maximizing energy recovery from existing infrastructures while contributing to sustainable energy production. Utilizing wind turbines to harness the energy potential of exhaust air from ducts presents an innovative approach in renewable energy generation. By strategically placing turbines within these ducts, the kinetic energy of the airflow can be captured and converted into electrical power. This method taps into an otherwise wasted resource, contributing to more efficient energy utilization within industrial or ventilation systems. The design and implementation of such turbines require careful engineering to optimize efficiency and ensure minimal disruption to the airflow. This approach holds promise for enhancing sustainability by tapping into untapped energy sources while reducing the carbon footprint of operations reliant on exhaust systems.
Turbine Based Power Generation: It works on the principle of conversion of kinetic energy into electric energy. In this process, a turbine is fixed near the opening of the silencer. A dynamo is attached to the turbine, which converts kinetic energy generated through the turbine into useful electrical energy. Efforts are being made to establish more innovative energy generation systems, better in terms of performance and economy, to cope up with the swelling demand of energy. Recovery of the waste energy, i.e., conversion of one form of waste energy into other useful form, is one of the important such approaches. Many energy recovery systems are being studied and evolved globally for useful power generation. Waste-to-energy (WtE) energy-from waste (EfW) is the process of generating energy in the form of electricity and/or heat from the primary treatment of waste, or the processing of waste into a fuel source. Industrial waste heat (Exhaust air) is abundant and represents significant energy inefficiency for many processes. This waste heat energy is carried by Duct systems in various industries, our aim is to generate electrical energy using this exhaust air and increase plant overall efficiency. Ducted exhaust air systems are used to extract contaminated air from industrial spaces and direct it outside.
INTRODUCTION Over the last couple of decades, mankind has realized that the continuous usage of petroleum fuels to meet the world’s energy demand, over the course of more than a century, has led to innumerable consequences. An inclination towards other sources for energy has come into the forefront. Yet, we are still a long way from completely phasing out petroleum as an energy source altogether. In such a time, any progress towards reducing the amount of fuel consumed during energy generation is good progress and cannot be neglected. The rest is wasted in the form of exhaust heat and noise. So, there is a scope for reclaiming the wasted power produced by the industry.
