The objective of this study is to investigate the combustion characteristics of completely pre-vaporized compound-drops spray flames using large activation energy asymptotics. Compound-drops are composed of an n-octane shell and a water core, and the premixed flame propagates in a steady, one dimensional flow. The influences of liquid spray loading and core water size on flame intensity, critical radius and shell fuel mass fraction are examined. The internal heat transfer involves both heat losses from water and heat gain from fuel for the lean spray burning. Thus, lean spray flames experience overall internal heat gain or heat loss, depending on the mass fraction of fuel in the compound-drops. While rich spray flames suffer only overall internal heat loss resulting from the gasification processes of both water and fuel.
