Estudio y diseño funcional de un horno crematorio energizado térmicamente con resistencias eléctricas.

Abstract

The present degree project presents a design study of a crematory oven energized with electrical resistances based on the concept of concurrent engineering. In accordance with one of the phases of this concept, the design of a reduced-size prototype that reproduces the same incineration phenomenon as the real size oven is also proposed. This study is developed in three correlated phases that consist of: first, bibliographic compilation, state of the art and thermal study in steady state; second, design and engineering; and third, cost analysis. In the first phase, an exhaustive investigation of crematory ovens available in the Ecuadorian and world market is carried out, as well as a thermal study in steady state for the potential design of refractory wall thicknesses, in order to obtain optimal efficiency at the lowest possible cost. In the second phase, the design itself is accomplished, based on the results obtained in the thermal study and the state of the art, determining technical specifications in a way that allows the development of a conceptual and modular design. This phase is made up of assembly, detail and workshop plans and 3D modeling. And, in the third phase, the total cost of construction and manufacturing of both the real crematory oven and the reduced-size prototype are detailed.
