                         teoria de deflagra{\c{c}}{\~a}o de sprays monodis persos de 
                         Williams. Aten{\c{c}}{\~a}o especial {\'e} dada ao 
                         crit{\'e}rio para combust{\~a}o homog{\^e}nea de sprays, isto 
                         {\'e}, o raio m{\'a}ximo r da gota para esse tipo de queima. 
                         Mostra-se que essa teoria fornece uma varia{\c{c}}{\~a}o 
                         incorreta do raio r com a temperatura de igni{\c{c}}{\~a}o. A 
                         partir de novas hip{\'o}teses, deduz-se uma nova express{\~a}o 
                         para essa varia{\c{c}}{\~a}o que evita esses problemas. Essa 
                         nova equa{\c{c}}{\~a}o apresenta uma melhor concord{\^a}ncia 
                         com os resultados experimentais. Analisa-se a regi{\~a}o da chama 
                         usando a transforma{\c{c}}{\~a}o de Kirchhoff. ABSTRACT: This 
                         dissertation presents a review of the laminar flame theory, 
                         droplets evaporation and combustion, and an introduction to the 
                         spray combustion. Furthermore, an analysis of the Williams' 
                         monodisperse spray deflagration theory is presented. Special 
                         attention is given to the criterion for spray homogeneous 
                         combustion, that is, the maximum droplet radius for this kind of 
                         spray burning. It is shown that this theory gives an incorrect 
                         variation of the radius r with ignition temperature. Therefore, a 
                         new expression for this variation is derived, based upon new 
                         hypothesis which avoids these problema. This new equation shows a 
                         better agreement with the experimental results. The flame region 
                         is analysed by using Kirchhoff's transformation.",
