An Internally fired semi-closed cycle gas turbine for Naval propulsion was designed and built for the U.S. Navy by the Westinghouse Electric Corporation. Due to a revision of the overall Navy propulsion program the plant was not tested at design conditions or mode of operation, but feasibility information for this configuration of gas turbine plant was obtained. Plant tests indicated that this cycle configuration can be expected to attain a significant reduction in shipboard space and weight requirements while matching existing conventional propulsion plant fuel and air consumption rates over a wide load range. The plant further is simply controlled to minimize manning personnel, permit bridge control, and has a brief transient period from cruise power to full load. Plants of this cycle configuration can be expected to produce large powers such as required for main ship propulsion while employing components of the size where considerable industrial experience has been accumulated. Fouling and corrosion of the internally fired, semi-closed cycle gas turbine were evaluated by the tests. Conventional gas turbine components are satisfactory for low sulfur fuel operation, and with additional precooler equipment development it is expected that high sulfur fuel operation will be achieved.

Vessel Material

Abstract The reactor vessel of the High Flux Reactor (HFR) in Petten has been fabricated from Al 5154-O alloy grade with a maximum Mg content of 3.5 wt. %. The vessel experiences large amount of neutron fluences (notably at hot spot), of the order of 1027 n/m2, during its operational life. Substantial damage to the material’s microstructure and mechanical properties can occur at these high fluence conditions. To this end, a dedicated surveillance program: SURP (SURveillance Program) is executed to understand, predict and measure the influence of neutron radiation damage on the mechanical properties of the vessel material. In the SURP program, test specimens fabricated from representative HFR vessel material are continuously irradiated in two specially designed experimental rigs. A number of surveillance specimens are periodically extracted and tested to evaluate the changes in fracture toughness properties of the vessel as function neutron fluence. The surveillance testing results of test campaigns performed until 2015 were published previously in [1, 2]. The current paper presents fracture toughness and SEM results from the recent surveillance campaign performed in 2017. The fracture toughness specimen tested in this campaign received a thermal neutron fluence of 13.56 x1026 n/m2, which is ∼8.9 × 1025 n/m2 more than the thermal fluence received by the specimen tested in SURP 2015 campaign. These results from this campaign have shown no change in the fracture toughness from the values measured in the previous SURP campaign. The SEM observations are performed to study the fracture surface, to measure (by WDS) the transmutation Si formed near crack tip and to investigate various inclusions in the microstructure. SEM fracture surface investigation revealed a tortuous (bumpy) fracture surface constituting micro-scale dimples over majority of the fracture area. Islands of cleavage facets and secondary cracks have been observed as well. EDS analysis of various inclusions in the microstructure revealed presence of Fe rich inclusions and Mg-Si rich precipitates. Additionally, inclusions rich in Al-Mg-Cr-Ti were identified. Finally, changes in mechanical properties of Al 5154-O alloy with an increase in neutron fluence (or transmutation Si) are discussed in correlation with SEM microstructure and fracture morphology observed in SEM. TEM investigation of precipitate microstructure is ongoing and those results will be published in future.

An investigation into the potential benefits of thermochemical recuperation and partial oxidation in advanced natural gas-fired turbine systems is being carried out by a team consisting of the Westinghouse Electric Corporation and the Institute of Gas Technology under contract to the U.S. Department of Energy and the Gas Research Institute. The purpose of this study is to determine whether the application of thermochemical recuperation and/or partial oxidation technologies to advanced natural gas-fired power generation systems provides performance and/or cost benefits. This paper presents an overview of the concepts and technologies which are under investigation, as well as several of the thermodynamic cycles which are being developed to determine their viability.

Cycle Efficiency

Through an alliance established in 1992 between Westinghouse Electric Corporation and Rolls-Royce plc, a program has been implemented that will bring the industrial Trent aero engine to the power generation marketplace. The Rolls-Royce Trent has been initially sized at 50 MW, with a development potential to higher power ratings, and is offered by Westinghouse as a complete power generation package, the “Trent EconoPac”. The Trent EconoPac sets a new performance standard in the industry with a nominal simple cycle efficiency of 42 percent. It is also ideal for combined cycle and cogeneration applications; a net combined cycle power of 63 MW at 52 percent efficiency can be developed. This paper describes the Trent industrial engine and EconoPac and reviews the development program with emphasis on unique features that benefit the power plant operator.
