RISInverted Brayton Cycle With Exhaust Gas Recirculation—A Numerical Investigation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microgas turbine (MGT) based combined heat and power (CHP) units provide a highly efficient, lowpollutant technology to supply heat and electrical power from fossil and renewable energy sources; however, pressurized MGT ...
Introduction of a New Numerical Simulation Tool to Analyze Micro Gas Turbine Cycle Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Micro gas turbine (MGT) technology is evolving toward a large variety of novel applications, such as weak gas electrification, inverted Brayton cycles, and fuel cell hybrid cycles; however, many of these systems show very ...
The Influence of Carrier Air Preheating on Autoignition of Inline-Injected Hydrogen–Nitrogen Mixtures in Vitiated Air of High Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of highly reactive hydrogen-rich fuels in lean premixed combustion systems strongly affects the operability of stationary gas turbines (GT) resulting in higher autoignition and flashback risks. The present study ...
Analysis of Operational Strategies of a SOFC/Micro Gas Turbine Hybrid Power Plant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present work deals with the analysis of operational concepts for a solid oxide fuel cell/micro gas turbine (SOFC/MGT) hybrid power plant based on a test rig at the DLR, Institute of Combustion Technology. Here, a Turbec ...
Optical Measurements of a Lower Calorific Values-Combustor Operated in a Micro Gas Turbine With Various Fuel Compositions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a recent joint research project, a new FLOX®-combustion system was developed to couple a fixed-bed gasifier with a micro gas turbine (MGT). Product gases from biomass gasification exhibit low calorific values and varying ...
Experimental Investigation of the Impact of Biogas on a 3 kW Micro Gas Turbine FLOX®-Based Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of biogas has currently two disadvantages. First, processing biogas to natural gas quality for feeding into the natural gas grid is a rather energy-consuming process. Second, the conversion into electricity directly ...
Development and Application of a Transported Probability Density Function Method on Unstructured Three Dimensional Grids for the Prediction of Nitric Oxides
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present work explores the capability of the transported probability density function (PDF) method to predict nitric oxide (NO) formation in turbulent combustion. To this end a hybrid finitevolume/Lagrangian Monte Carlo ...
Sensitivity Analysis of Auto Ignition Simulation at Gas Turbine Operating Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
