Grant Description: NOTE: This descriptive area provides an overview of Technical Topic Area 2: Sub-Topic 2.2: Film Cooling and Innovative Cooling Approaches only.

Please scroll to the bottom of this page to access the Funding Opportunity Announcement. Topic Area 2 - Aero/Heat Transfer Low heating values typical of syngas and injection of diluents (to control combustion temperatures and therefore thermal NOx) have resulted in higher (up to 14%) mass flows through the turbine hot section of IGCC turbines than for the same model turbines operated with natural gas. This produces 20-25% higher turbine output power compared to natural gas but also tends to increase the heat transfer to the hot section vanes and blades. Where steam is used as a diluent to control NOx, the higher heat transfer properties for steam compared to air tends to additionally increase the heat load to hot section components. Accordingly, current IGCC turbines have been operated at reduced firing temperatures to maintain hot gas parts at temperatures similar to those of the same model turbines operated with natural gas. The progression from current syngas to HHC fuels produced from coal syngas along with the usual increase in turbine inlet temperature through time to increase performance (power and efficiency) will tend to produce additional heat loads and aero/cooling requirements for hot section components. Also, limited turbine operation experience and past rig tests with alternate fuels containing ash impurities have shown that corrosion and deposition can be drastically higher for increased inlet temperatures because of higher levels of molten phases in the flow stream. Although increased gas cleanup in future plants will probably significantly reduce impurities entering the turbine, current experience has shown that even highly filtered ambient air can produce significant deposition (fouling) in compressors when molten phases exist at flow path conditions. Consequently, additional research is needed to define the aero/heat transfer environments and accommodate higher heat loads under potential deposition/corrosion conditions in the hot section flow paths of turbines operating with HHC fuels derived from syngas. Sub-Topic 2.2: Film Cooling and Innovative Cooling Approaches (DE-PS26-08NT00165-2B) Research is needed to identify and verify film cooling approaches (geometries, hole locations and patterns, etc.) that enable designs that sustain cooling effectiveness and passage aerodynamic efficiency through being relatively insensitive to degradation effects such as deposition, erosion, corrosion, or coating spallation. Research that evaluates and verifies innovative surface cooling approaches that can reduce deposition, erosion, or corrosion effects is also desired. Effects on cooling effectiveness should be at least analytically evaluated for a range of flow path heat transfer properties (e.g., resulting from different water vapor levels) associated with HHC fuels derived from syngas. Candidate cooling approaches to be explored should be first discussed with turbine suppliers to consider their manufacturability.
