Abstract
A fuel injection system is provided for gas turbines or the like which includes a pair of high pressure pumps which provide fuel and a carrier fluid such as air at pressures above the critical pressure of the fuel. A supercritical mixing chamber mixes the fuel and carrier fluid and the mixture is sprayed into a combustion chamber for burning therein. The use of fuel and a carrier fluid at supercritical pressures promotes rapid mixing of the fuel in the combustion chamber so as to reduce the formation of pollutants and promote cleaner burning.
Claims7
A fuel injection system comprising means defining a combustion volume;
- means for supplying pressurized fuel at a pressure above the critical pressure thereof, means for supplying a pressurized carrier fluid at a pressure above the critical pressure of the fuel, mixing means for mixing said pressurized fuel and said pressurized carrier fluid to produce a fuel/carrier fluid mixture, and means for supplying said fuel/carrier fluid mixture to said combustion volume for combustion therein.
