In this work it was made an analysis of the combustion in a cyclonic combustor through experimental measures of the temperature and gases concentration in the internal wall of the combustion chamber. With the objective of finding an appropriate operational parameters for the proposed design, the feeding of air and sawdust of combustor was varied in a poor equivalence ratio (with excess of air) while the experimental data were computed. The data profiles obtained were confronted with the theory of the combustion of solids and with the temperature fields and gases concentration founded by Cunha (2005) numerically in the code Fluent V.6.0. In this comparison it was possible to find good qualitative value among the temperatures measured and the one from calculations, however there were differences in the topic concentration of gases. It was possible also to identify the minimum equivalence rate that the cyclonic combustor had in their gaseous products low pollutant tenors, like CO. Besides, at the end of this work a methodology was proposed to find the appropriate size of a cyclonic combustor in agreement with the strip of sawdust consumption that it wants to incinerate.
