Determinar los Perfiles de Temperatura de un Horno para Ladrillos del Sector Chambo.

Abstract

A simulation through finite elements for the obtaining of temperature profiles of a handmade brick oven was carried out in this thesis work. The analyzed variables were speed rise of combustion gases, relationship of the oven dimensions height / half of the width, space among each brick when being stowed and wall thinckness for the square oven. The temperature average and the temperature profiles are important because they determine in great measure the quality of the final product. To achieve the objective mathematical models were set out in stationary states, which include conduction, convection and radiation terms. The solution was carried out using computing software. The most representative variable was the speed at which the combustion gases ascend. To obtain a more homogeneous temperature distribution inside the oven it is necessary to maintain a constant flame temperature and try to expose the biggest number of bricks to the fire. The wall thickness as well as the space among the bricks showed not to have significant effect. Inside the graphs of a first simulation it was found that the bricks located in the superior lateral parts don´t end up completing the cooking, that is why it was considered in a second simulation the help channels where the additional fuel is placed to compensate the missing temperature, channels that have been traditionally used by the brickmakers, confirming in this way that a better heat distribution is achieved to all the oven bricks.
