Diseño y construcción de una cocina ecoeficiente a leña para una familia de 5 miembros.

Abstract

This thesis deals with the design and construction of an eco-efficient stove, which was installed in the parish of Amaguaña. This type of eco-efficient stoves is useful, especially, in places where there are few domestic gas distribution points and firewood is accessible. Through the research of the state of the art, these types of eco-efficient cookstoves, which exist today in the market, were determined and was taken as a starting point for the design of this project. Subsequently, the technical specifications and the sizing, that the stove must have to meet the energy requirements for use in a family of five people, were established. For this purpose, a thermal efficiency of 30% was assumed, and this value was verified once the stove was built, obtaining a real efficiency of 27%. Moreover, the pertinent calculations of heat delivered by the firewood and the losses that exist in the stove were calculated. After that, the stove was built based on the assembly, subassembly and workshop drawings showing the necessary measurements, materials and specifications. In order to verify the correct operation of the stove, temperature control, water boiling, cooking and operation tests were carried out; so, it was found that the heating times were between 10% and 35% less than those obtained in traditional stoves such as GLP stoves. Finally, Once the stove was built and its correct operation was verified, the direct, indirect, and labor costs associated with the construction of the eco-efficient stove were analyzed.
