Industrial Gas Turbine

An industrial gas turbine can run on a wide variety of fuels to produce power. Depending on the fuel composition and resulting properties, specifically the hydrogen–carbon ratio, the available output power, operability, and emissions of the engine can vary significantly. This study is an examination of how different fuels can affect the output characteristics of Solar Turbines Incorporated industrial engines and highlights the benefits of using fuels with higher hydrogen–carbon ratios including higher power, higher efficiency, and lower carbon emissions. This study also highlights critical combustion operability issues that need to be considered such as auto-ignition, flashback, blowout, and combustion instabilities that become more prominent when varying the hydrogen–carbon ratio significantly. Our intent is to provide a clear and concise reference to edify the reader examining attributes of fuels with different properties and how natural gas is superior to other fossil fuels with lower hydrogen carbon ratios in terms of carbon emissions, power, and efficiency.

Industrial Gas Turbine

This paper describes the aerodynamic optimization of the GT26 exhaust diffuser. The need for optimization was triggered by an upgrade of the compressor, resulting in a higher mass flow and a higher power output. The expansion turbine remained unchanged. However, the increase in mass flow had a significant impact on the Mach number. Secondly, the residual swirl at the turbine outlet, and therefore, the exhaust loss in original diffuser would have increased. The re-optimization of diffuser allowed minimization of the losses and improvement of the overall engine performance.

This paper presents a mathematical model for computing the effects of air humidity, fuel composition, and gas dissociation on gas turbine engine performance and its actual application to a computer program for simulation of gas turbine engine performance. A new generalized modular program to allow for these effects was built, which is called ‘TURBOFLEXI’. It can simulate arbitrary gas turbine engine with a variety of configurations, at any air humidity conditions, with any fuel composition and gas dissociation or even water injection. The program was examined by test data and published data.

Conceptual design evaluations of the use of continuous fiber ceramic composite (CFCC) turbine shrouds and combustor liners in an industrial gas turbine engine were performed under Phase 1 of the DOE CFCC program. Significant engine performance improvements were predicted with the use of CFCC components. Five composite systems were evaluated for use as shrouds and combustor liners, the results of which are discussed with particular reference to Toughened Silcomp. Several current CFCC materials were judged to be relatively close to meeting the short term performance requirements of such a system. However, additional CFCC property data are required for significant component design optimization and life prediction, two key design steps that must be completed before ceramic composites can be utilized in large gas turbines.

After briefly summarizing worldwide automotive gas turbine activity, the paper analyses the power plant requirements of a wide range of vehicle applications in order to formulate the design criteria for acceptable vehicle gas turbines. Ample data are available on the thermodynamic merits of various gas turbine cycles; however, the low cost of its piston engine competitor tends to eliminate all but the simplest cycles from vehicle gas turbine considerations. In order to improve the part load fuel economy, some complexity is inevitable, but this is limited to the addition of a glass ceramic regenerator in the 150 b.h.p. engine which is described in some detail. The alternative further complications necessary to achieve satisfactory vehicle response at various power/weight ratios are examined. Further improvement in engine performance will come by increasing the maximum cycle temperature. This can be achieved at lower cost by the extension of the use of ceramics. The paper is intended to stimulate the design application of the gas turbine engine.
