Diseño de un sistema para la obtención del gas pobre en el gasificador DOWNDRAFT de la Escuela de Ingeniería Mecánica.

Abstract

This thesis presents the design and implementation of a collection system lean gas in a gasifier Downdraft type, with which it aims to improve the quality of the gas produced in terms of reducing particulate matter control flows gas flow and density. Prior to sizing equipment function tests they were performed gasification equipment to corroborate the theoretical values of processing capacity, flows and temperatures. The gasifier is designed to feed biomass 40kg, tests were part of the plant operation training to 75% of the installed power. Through established design values it is designed and implemented various systems to improve gas quality. Considering the purity of the gas, an outer fabric filter capable of retaining particles of a size less than 50μm is set. For a flow control and gasifying agent quantify the amount of gas produced by ISO 5167, it is designed cuadalímetros two differential pressure orifice plate type. And finally, on the subject of density value, it is proposed that the poor gas is cooled in a heat exchanger, and the heated fluid is air which is introduced as a gasifying agent. In performance test the proper sizing of the above systems is confirmed.
