Desarrollo, construcción y pruebas de un sistema de uso de biogás como combustible en un motogenerador eléctrico rural.

Abstract

A biogas as fuel in an electric Moto generator was developed, built and tested in this present investigation in order to use this fuel that is produced in the bio digester that is in production at Agrogana farm, located on Latacunga city. It is pretended to replace the fuel with biogas with application to generate electricity. An experimental and theory analysis of the internal-fuel motor running was carried out. The percentage of H2S was reduced through an iron filings filter in order to take advantage the biogas. A device passing by a hole having a determined diameter was used for the biogas power in order not to modify the engine integrity regarding the mechanisms. Experimental tests were carried out to find the torque, potency and specific fuel consumption parameter by using fuel and biogas to find the engine feature curves. The evaluation of the parameter mentioned above was gotten by changing the charge by incandescent – bulb panel. An arm adjusted to the generator arm to a scale allows measuring the torsional force generated by the engine for a determined charge. An anemometer measures the biogas flow speed in the engine. It is demonstrated that the adaptation of a fuel engine to biogas is feasible using the same engine and accessories without any further variation in the running.
