ABSTRACT:
An apparatus and method are provided for the reduction of NOX emissions and the augmentation of output from a dual fueled (gas/oil) turbine such as an electrical power generating turbine. The invention involves using pathways already existing in a turbine for injecting air into a combustion chamber for transporting water into the combustion chamber, especially when fueled with oil. Ideally only minimal modifications to the turbine are necessary, but generally the invention decreases the time and expense for modifying an existing turbine to include water injection capabilities to increase output or decrease NOX emission.
