Abstract
There is provided a water-hydrocarbon mixture. In one example, the mixture includes low-molecular weight hydrocarbon and between about 5% and about 70% water. The mixture is in the gaseous state, and is at a pressure that is below the critical pressure of the mixture. The mixture temperature is above about 28° C. less than the boiling point temperature of water at the mixture pressure and is below about 450° C. The mixture provides a local environment of water molecules, tending to limit hydrocarbon polymerization and other undesirable side reactions and keeping the hydrocarbon from precipitating from the mixture, for a faster, more complete combustion cycle characterized by lower emissions of carbon monoxide, unburned hydrocarbons, and volatile organic and polyaromatic hydrocarbons. The hydrocarbon preferably includes hydrocarbon micro-droplets of a diameter of no more than about 1 &mgr;m.
