SUB-CRITICAL WATER-FUEL COMPOSITION AND COMBUSTION SYSTEM

摘要

There is provided a water-hydrocarbon mixture, and method for its formation and combustion. Comprising about 5 % and about 70 % water. The mixture is at a pressure that is below the critical pressure characteristic of the mixture a nd is at a temperature that is at least the greater of about 250 ~C and about t he boiling point temperature of water at the mixture pressure. The mixture provides for a faster, more complete combustion cycle that is 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 .mu.m. In o ne embodiment, both the water and the hydrocarbon of the mixture are in a gaseo us state.
