Abstract: A simple-cycle gas turbine system includes an injection system including a plurality of injection tubes that may inject a fluid into a duct of an exhaust processing system that may process exhaust gas generated by a gas turbine engine. The exhaust processing system includes a selective catalytic reduction (SCR) system that may reduce a level of nitrogen oxides (NOx) within the exhaust gas; and a mixing system positioned adjacent to the plurality of injection tubes and within the exhaust processing system. The mixing system includes a mixing module having a plurality of turbulators that may swirl the fluid, or the exhaust gas, or both, in a first swirl direction to encourage turbulent flow along an axis of the exhaust processing system and thereby facilitate mixing between the fluid and the exhaust gas.

Abstract: Gasifier preheater fuel and moderator injection apparatus, systems and methods are provided. A preheater distributor ring is securely mounted within the shell dome of a gasification vessel, for the selective discharge of preheat fuel and oxidizer into the vessel during preheating operations, or for the selective discharge of moderating agents into the vessel during normal gasification operations.

Abstract: A turbine assembly comprising a hub and a plurality of vanes. The hub has a plurality of slits angularly disposed thereon. The plurality of vanes, each comprises an interior edge and an exterior edge. Each of the plurality of vanes has curvature and trespasses the plurality of slits. Exterior edges on the plurality of vanes comprise at least two protrusions. The protrusions fill channels defined in an air intake line of an engine, thereby allowing the hub to spin within the air intake line to create a vortex.
