Abstract: An approach for estimating deposition in gas turbines is described. This approach extrapolates deposition data from lower cost experiments than turbine engine or cascade tests. The purpose is a ...

Abstract: A previously proposed systematic approach for the analysis of gyroscopic drifts associated with angular support motions is further developed. For a wide range of support motions, the problem of ...

Abstract: Using turbine deposition models and data from PFBC (pressurized fluidized bed combustion) pilot plant/cascade experiments, deposit buildup rates and turbine maintenance intervals to remove deposits ...

Abstract: Experiments using cascades and small turbines have been conducted or are being considered to simulate large utility turbine operation with future coal-fired power plants. The purpose of these ...

Abstract: Exact dynamical and kinematical equations governing motions of a two-degree-of-freedom gyroscope mounted on a moving vehicle are formulated. From these equations, a set of simpler ones is derived ...

Abstract: Deposition, erosion, and corrosion (DEC) experiments were conducted using three coal-water fuels (CWF) in a staged subscale turbine combustor operated at conditions of a recuperated turbine. This ...

Abstract: A staged, subscale turbine combustor based on a promising rich-quench-lean combustion approach to reduce NOx emissions was used to evaluate deposition, erosion, and corrosion (DEC) from coal-water ...

Abstract: A rich-quench-lean subscale turbine combustor has been used to expose specimens to the products of combustion from several beneficiated coal-water fuels. An analytical scheme is formulated to ...

Abstract: Burning residual oil in utility combustion turbines and the consequent deposition on blades and vanes may adversely affect reliability and operation. Corrosion and deposition data for combustion ...
