Abstract
Supercritical water fuel composition and combustion system. In one aspect, the invention is a composition of matter comprising a mixture of 5-50% water and a hydrocarbon wherein the water/hydrocarbon mixture is near the critical point such that the mixture is a homogeneous single phase. A suitable temperature is 400.degree. C. and a suitable pressure is 4,000psi. In another aspect, the invention is a fuel system including structure containing a water/hydrocarbon fuel mixture near the critical point such that the mixture is a homogeneous single phase. Structure is provided for delivering the mixture for combustion. Combustion may occur in an internal combustion engine, turbine engine or other burner.
Claims25
Composition of matter comprising a mixture of 5-70% water and a hydrocarbon wherein the water/hydrocarbon mixture is at or above the critical point such that the mixture is a homogeneous single phase.
Fuel system comprising:
- structure containing a mixture of 5-70% water and hydrocarbon fuel wherein the mixture is at or above the critical point such that the mixture is a homogeneous single phase;
- and
- means for delivering the mixture into a combustion chamber.
A fuel injection system for a furnace or power plant burner system comprising means for injecting a mixture of 5-70% water and hydrocarbon fuel into the burner system wherein the mixture is at or above the critical point such that the mixture is a homogeneous single phase.
Fuel system comprising:
- a source of water;
- a source of hydrocarbon fuel;
- a dual fluid, pressure limited high pressure metering pump having an inlet connected to the source of water and source of hydrocarbon and having an outlet;
- an injector volume connected to the pump outlet for receiving high pressure water and hydrocarbon fuel, the injector volume including heating means to heat a water/hydrocarbon fuel mixture, the mixture having 5-70% water, the injector volume further including a control valve to control discharge of the water/hydrocarbon fuel mixture, the temperature and pressure of the water/hydrocarbon fuel mixture being at or above the critical point such that the mixture is a homogeneous single phase.
