Análise da eficiência de um gaseificador operando com biomassa residual e carvão vegetal

Abstract

In order to increase demand by energy, especially in developing countries as Brazil, is been to need looking for new technologies in generation and distribution of this energy. Biomass gasification is one the way toreplace combust fossil fuel without need todependency of sun, wind speed and the rain season. The goals of the present works arecompared efficiency of the gasifierin the gasification process with the in natura biomass and charcoal. The methodology was built by gasification, biomass and charcoal. Usedanopen top, fixed bed drawdraft gasifier, with engine / generator Toyama TG 2500 MX, a 280 W resistor type load simulator, and a gas analyzer. To obtain the percentage of carbon monoxide (CO) present in the gas produced in the gasification process. The results showed that the charcoal presented a better consumption thanin natura biomass, in addition replacing a natural biomass with vegetable charcoal eliminates the drawbacks of the tar in the system. Another point of observation was the maximum means of the gasifier, which using in natura biomass was 81.77% and with the coal it obtained 76.10%.
