RISPredicting Flameholding for Hydrogen and Natural Gas Flames at Gas Turbine Premixer Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Leanpremixed gas turbines are now common devices for low emissions stationary power generation. By creating a homogeneous mixture of fuel and air upstream of the combustion chamber, temperature variations are reduced within ...
Examination of Predictive Flame Extinction Boundaries for Bluff Body Stabilized Flames at Elevated Temperature and Pressure Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A correlation for the prediction of flame lean extinction limits for premixed combustion systems by Sullivan-Lewis and McDonell is examined. The correlation was developed with the data collected from Sullivan-Lewis' ...
Study of Fuel Composition Effects on Flashback Using a Confined Jet Flame Burner
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flashback is the main operability issue associated with converting lean, premixed combustion systems from operation on natural gas to operation on high hydrogen content fuels. Most syngas fuels contain some amount of ...
Study of Fuel Composition, Burner Material, and Tip Temperature Effects on Flashback of Enclosed Jet Flame
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flashback is a key challenge for low NOx premixed combustion of high hydrogen content fuels. Previous work on jet burner configurations has systematically investigated the impact of fuel composition on flashback propensity, ...
Flashback Propensity of Turbulent Hydrogen–Air Jet Flames at Gas Turbine Premixer Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flashback propensity of a premixed jet flame has been studied experimentally. Boundary layer flashback has been investigated under turbulent flow conditions at elevated pressures and temperatures (i.e., 3–8 atm and ...
Application of a Turbulent Jet Flame Flashback Propensity Model to a Commercial Gas Turbine Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Because flashback is a key operability issue associated with low emission combustion of high hydrogen content fuels, design tools to predict flashback propensity are of interest. Such a design tool has been developed by ...
Emulsion Jet in Crossflow Atomization Characteristics and Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents the atomization characteristics and dynamics of water-in-heptane (W/H) emulsions injected into a gaseous crossflow. W/H mixtures were tested while varying momentum flux ratios and aerodynamic Weber ...
Flashback and Turbulent Flame Speed Measurements in Hydrogen/Methane Flames Stabilized by a Low Swirl Injector at Elevated Pressures and Temperatures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports flashback limits and turbulent flame local displacement speed measurements in flames stabilized by a low swirl injector operated at elevated pressures and inlet temperatures with hydrogen and methane ...
Influence of Burner Material, Tip Temperature, and Geometrical Flame Configuration on Flashback Propensity of H2 Air Jet Flames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flashback is a key operability issue for low emission premixed combustion systems operated on high hydrogen content fuels. Previous work investigated fuel composition impacts on flashback propensity and found that burner ...
Evaluation of the Level of Gaseous Fuel Bound Sulfur on Fine Particulate Emission From a Low Emission Gas Turbine Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present work investigates the effect of natural gas fuel sulfur on particulate emissions from stationary gas turbine engines used for electricity generation. Fuel sulfur from standard line gas was scrubbed using a ...
