Abstract

A system to recover part of the energy of exhaust air from an axial fan of 75kW using a Horizontal Axis Wind Turbine is discussed in this paper. The actual air data at the fan outlet are collected from central air conditioning station of a composite textile mill (Kombolcha Textile Share Company) using log-Tchebycheff method. Since the air flow type determines the steps in progress the air flow type is arithmetically found to be fully turbulent. A duct is designed to correct the air turbulence and transport the exhaust air from the fan to the turbine. The enclosure duct design is developed in consideration of the actual situation of the company to attain a fully developed region where the air speed attains a uniform velocity profile and create a venturi effect (to increase the air speed) for better energy output and guide the air before it interacts with the wind turbine blades. By turning what was exhausted to useable form 5.7kW of electric power can be harvested. As there are vast application areas of industrial air system, utilizing the exhaust from such air systems as energy resource could be helpful and used as supplementary power for industry production floor lighting and little power supply requiring auxiliary processes.
