The present work aims to study the thermal energy losses of a firewood kiln used in the production of clay craftwork in the district of Alto do Moura in Caruaru-PE. Firstly, a previous survey was carried out with the artisans regarding the amount of firewood used, through questionnaires answered by them. An experimental analysis of a kiln was carried out during its operation, measuring and marking several points on it. Subsequently, the temperature and speed of the recording of all the data obtained were periodically recorded. The kiln was treated as a control volume that operates in a transient regime based on the equations of Energy Conservation, Heat Transfer and in the equation of Stoichiometric Balance of firewood combustion with performed calculations aided by software like Excel, for an estimate of heat losses to the environment by convection and radiation. Finally, energy losses were evaluated, enabling the proposal to the artisans of modifications in the kilns, aiming at the increase of kiln efficiency.
