Diseño térmico de un incinerador patológico eléctrico en estado transitorio.

Abstract

This work aims to carry out the thermal design of an electrical pathological incinerator in a transient state. To face the thermal design, it has been considered to establish a mathematical model by the method of finite differences (explicit method), so that the previous temperatures of each node will be used to calculate the current temperature, and so on. With the mathematical model developed, the time for the incinerator furnace to reach working temperatures will be determined, depending on the electrical power supplied. To evaluate the thermal behavior in the transient state, it is necessary to determine the thermal capacitances of the incinerator furnace based on the properties of each material. The power that must be supplied to the furnace will be analyzed from the technical and economic point of view, seeking to obtain an equitable proportion between these two variables. As design alternatives, you have the possibility of using two insulating materials, which are fiber cement and glass wool. The simulation determines the times and temperature distributions for each material and with different input electrical powers. The results of the thermal design are obtained for two prototypes in scale size and two equipment in real dimensions, therefore, the selection of the best alternative for the construction of the furnace will be from the project team in conjunction with the other components of the design. With the analysis of the behavior of the results obtained, for several input powers altering the conclusions and recommendations are established.
