Abstract
El presente trabajo de investigación desarrolla el diseño, fabricación y caracterización de un prototipo de quemador de medio poroso inerte para una aplicación tradicional, puntualmente como quemador de cocina semi-industrial, todo lo anterior en el marco del proyecto de valorización de la investigación en la universidad (VIU15E0022) adjudicado para el desarrollo de esta tesis.El prototipo es ensayado tomando en consideración variables como: temperaturas de operación, flujos de combustible y aire de alimentación, materiales de fabricación tanto para el cuerpo del quemador, como para el medio poroso inerte y finalmente el combustible a utilizar (Gas natural o gas licuado). Luego de desarrollar las mediciones experimentales se pudo caracterizar el quemador, para ambos combustibles anteriormente mencionados, en términos de su rango de potencia, que se encuentra en el rango de 1:2.5 (2 a 5 [kW]) para el gas licuado con una buena estabilidad para mezclas pobres y con un rango de 1:2.6 (1.5 a 4 [kW]) para el gas natural.Además, se pudo generar la comparativa con un quemador tradicional en la misma aplicación en términos de eficiencia de combustión, utilizando una metodología de calentamiento de agua. En términos comparativos, ambos quemadores obtuvieron un valor similar de eficiencia, alrededor de 27 [%] para el gas licuado (quemador convencional 26 [%]) y un valor de 32 [%] para el gas natural (quemador convencional 34 [%]).Luego de la caracterización se deja registro de varios prismas de mejoras asociados al prototipo I que permitirán una mejoría cuantitativa en términos de rendimiento y costos de fabricación que permitirán crear un nuevo prototipo más competitivo en un mercado objetivo y también en nuevos mercados donde se pudiese aplicar la tecnología como se detalla en el estudio de mercado realizado para esta investigación.
This research work develops the design, manufacture and characterization of a inert porous medium burner prototype, for a traditional application, specifically as a semi-industrial kitchen burner, all of the above in the framework of the research valorization project in the university (VIU1Ee0022) awarded for the development of this thesis.The prototype is tested taking into consideration variables such as: operating temperatures, fuel flows and feed air, manufacturing materials for both the burner body, the inert porous medium and finally the fuel to be used. After developing the experimental measurements, the burner could be characterized, for both fuels previously mentioned, in terms of its power range, which is in the range of 1: 2.5 (2 to 5 [kW]) for liquefied gas with a good one for me and with a range of 1: 2.6 (1.5 to 4 [kW]) for natural gas.In addition, the comparison with a traditional meter can be generated in the same application in terms of combustion efficiency, using a water heating methodology. In comparative terms, both burners obtained a similar efficiency value, around 27 [%] for liquefied gas (conventional burner 26 [%]) and a value of 32 [%] for natural gas (conventional burner 34 [%])After the characterization, a record of several prisms of improvements associated with the prototype is left. That can be used in terms of terms and manufacturing costs that can create a new more competitive prototype in a target market and also in new markets. Technology as detailed in the market study conducted for this research.
