RISRole of Oxidizer Mixture Composition on Stabilizing Stratified Oxy-Flames in Dual Lean Premixed Combustors for Gas Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigates the effects of oxidizer composition on stability and combustion and emission characteristics of stratified premixed CH4-O2-CO2 flames in a dual annular counter-rotating swirl (DACRS) burner for wider ...
Stability and NOx Emissions of Oxy-Ammonia Swirl Premixed Flames in an Emissions-Controlled Gas Turbine Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This study provides a design-relevant numerical analysis of ammonia–oxygen (NH3/O2) combustion, focusing on the effects of inlet preheating (298–520 K), equivalence ratio (φ = 0.7–1.2), and bulk flow velocity ...
Boilers Optimal Control for Maximum Load Change Rate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In many cogeneration systems, one or more boilers are used in hot standby to meet the plant demand of steam in case of failure or upset in the cogeneration unit. Such boilers need to quickly respond to sudden and large ...
