Abstract

The objective of this work is to perform the thermal design of an electric pathological incinerator in the steady state. In order to carry out the thermal design of the steady state, we start with the geometric design and proceed with the selection of materials for the incinerator walls, the main function of each of the walls is to reduce energy losses by heat transfer to the environment. As alternatives of the thermal design, there is the possibility of using two insulating materials, fiber cement and glass wool. The sizing of the walls will be done through an iterative process based on a mathematical model developed for the steady state, so that the furnace is sized, materials are selected, heat losses are established, the working temperature of the furnace and the power required for the incineration process are determined. To start the steady state thermal analysis of the incinerator furnace, some specific operating requirements are considered, these values are requirements of the mechanical component of the project and are internal surface temperature of the furnace, external surface temperature of the furnace. The thermal simulation will allow to obtain the interface temperatures between the furnace walls and to observe the steady state behavior for each material. For the development of the mathematical model, the analysis of the thermal circuit of the incinerator furnace is carried out considering that the heat will be unidirectional and as a compound wall. The results of the thermal design are obtained for two scale prototypes and two full-size models of the incinerator furnace and the energy required to incinerate the load is calculated.
