(The American Society of Mechanical Engineers (ASME), 1998)The General Electric Company has developed and successfully tested a full-scale, F-class (2550°F combustor exit temperature), rich-quench-lean (RQL) gas turbine combustor, designated RQL2, for ... -
Black Liquor Gasifier/Gas Turbine Cogeneration
(The American Society of Mechanical Engineers (ASME), 1998)The kraft process dominates pulp and paper production worldwide. Black liquor, a mixture of lignin and inorganic chemicals, is generated in this process as fiber is extracted from wood. At ... -
An Experimental Determination of Losses in a Three-Port Wave Rotor
(The American Society of Mechanical Engineers (ASME), 1998)Wave rotors, used in a gas turbine topping cycle, offer a potential route to higher specific power and lower specific fuel consumption. In order to calculate this potential realistically, a ... -
Ceramic Coating Edge Failure Due to Thermal Expansion Interference
(The American Society of Mechanical Engineers (ASME), 1998)An investigation of thermal barrier coatings on a metal substrate was conducted when the assembly was subjected to both thermal heating and mechanical edge loads generated by interference in ... -
Optical Measurement of Wet Steam in Turbines
(The American Society of Mechanical Engineers (ASME), 1998)The wetness fraction of steam causes dangerous erosion of turbine blades and other components, and decreases efficiency of stages. The instrumentation of wet steam has, therefore, attracted growing ... -
Analysis of Interfacial Cracks in a TBC/Superalloy System Under Thermomechanical Loading
(The American Society of Mechanical Engineers (ASME), 1998)In thermal barrier coatings (TBC) residual stresses develop during cool down from processing temperature due to the thermal expansion mismatch between the different layers (substrate, bond coat, ... -
Use of an Expert System to Study the Effect of Steam Parameters on the Size and Configuration of Circulating Fluidized Bed Boilers
(The American Society of Mechanical Engineers (ASME), 1998)CFBCAD©, an Expert system developed jointly by the authors, is used to investigate into the effect of steam parameters on the size and configuration of circulating fluidized bed (CFB) ... -
The Development of a Combustion System for a 110 MW CAES Plant
(The American Society of Mechanical Engineers (ASME), 1998)The use of stored energy systems is receiving increased attention for power generation. Alabama Electric Co-operative (AEC) have installed a 110 MW Compressed Air Energy Storage (CAES) plant at ... -
Modeling Piston-Ring Dynamics, Blowby, and Ring-Twist Effects
(The American Society of Mechanical Engineers (ASME), 1998)A ring-dynamics and gas-flow model has been developed to study ring/groove contact, blowby, and the influence of ring static twist, keystone ring/groove configurations, and other piston and ring ... -
Time-Dependent Crack Initiation and Growth in Ceramic Matrix Composites
(The American Society of Mechanical Engineers (ASME), 1998)Matrix cracking in ceramic matrix composites with fine grained fibers at high temperatures will be governed by fiber creep, as relaxation of the fibers eliminates crack tip shielding. Using a ... -
Influence of the Exhaust System on Performance of a 4-Cylinder Supercharged Engine
(The American Society of Mechanical Engineers (ASME), 1998)Twin entry radial turbines are mostly used to drive compressors of small and medium size 6-cylinder diesel engines where the available energy of the undisturbed exhaust pulses can be efficiently ... -
