Analysis of a Coffee Husk Fired Cogeneration Plant in South Western Ethiopia Coffee Processing Industries

Abstract

Nowadays our energy needs have grown exponentially corresponding with human population growth and technological advancement. Energy consumption linked to non-renewable resources contributes to greenhouse gas emissions and enhances resource depletion. Most of the researchers were proven that the worldwide concern about CO2 emissions and the reduction in the use of coal fuels have increased the interest in using biomass fuel for electricity production, because there is no net increase in CO2 emissions from biomass (agricultural residues such as straw, bagasse, coffee husk, and rice husks) combustion. Furthermore, coffee husk which has high energy potential was not taken into account for the generation of energy. However, this paper investigates the energy generation in coffee husk, and suggests coffee husk is an energy source. The datum was collected from the south western region of Ethiopia (Taipei town), and its equipment was selected. Coffee husk was tested experimentally in Addis Ababa University with Eager 300 software for running the equipment, storing the data and analyzing. The results obtained that calorific values were 18.98 MJ/kg. Overall the result demonstrates that the proposed coffee husk has high energy potential for the generation of energy.
