Optimization of Exergy Efficiency and Exergo-Environmental in Reactor Bubbling Fluidized Ged Gasifier

Abstract

The impact of technology for the environments must be consider to maintain the health of the earth. A technology gives a chance to reduce human labor, but we need a technology that can help us to keep the environment clean as possible. Exergo-environmental can be used to predict the harm from build the technology, so we can make a consideration to build the technology. This study presents the optimization of energy efficiency and exergo-environmental from reactor bubbling fluidized bed gasifier, with rice husk as biomass, air as agent gasification. Equivalent ratio (ER) and temperature varied in range 0.25-0.45 and 650-800oC sequentially. The result show that ER 0.25 with temperature 650oC give the best value for the operating condition in the reactor, with value of the efficiency is 43.1%, with the lowest value from the exergo-environmental.
