Low-NO_X Emissions in a Fuel Flexible Gas Turbine through the Integration of Fuel Composition Control and Combustor Design
DE-FC26-03NT41892

In October of 2003, the National Energy Technology Laboratory entered into a Cooperative Agreement with General Electric Power Systems to design a gas turbine combustor system for new and existing turbines.  The system will combine active air flow control and fuel composition control to achieve emissions of 2 parts per million NO_X. The system will be designed to operate on both coal gas and natural gas due to the fact that most integrated gasification combined-cycle (IGCC) systems use natural gas as an alternative fuel and there is a large infrastructure of existing natural gas based turbines. 

This work will proceed in three phases.  Phase I will develop a conceptual design of a turbine combustor with active air flow control and fuel composition control and then assess the economic viability versus selective catalytic reduction (SCR). In Phase II, a fuel processor will be designed and built to produce an optimized fuel and the two systems will be integrated and tested.  In Phase III, a full scale field demonstration will be conducted of the integrated fuel generator-combustor with a turbine.
