RISTurbulent Burning Velocity of High Hydrogen Flames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The turbulent burning velocity (ST) is one of the most important combustion properties controlling combustor operability limits, directly influencing blowoff, flashback, and combustion instabilities. Hydrogen has particularly ...
Toward the Development of an NH3-RRQL System—Part II: Effects of the Primary Combustion Zone Length and Secondary Stage Number of Holes on Stability and Emissions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Staged combustion systems like the rich–relaxation–quench–lean (RRQL) offer the potential for low nitrogen oxides (NOx) emissions while burning ammonia (NH3). This process involves rich premixed NH3–air combustion ...
Toward the Development of an RRQL System—Part I: Swirl Pattern Effect on Exhaust Emissions and Chemiluminescence Distribution for NH3–Air Premixed Swirl Flames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Ammonia (NH3) is a carbon–free energy source and hydrogen carrier, but its fuel–bound nitrogen can lead to significant nitrogen oxides (NOx) emissions. Staged combustion strategies, such as rich–quench–lean, can ...
Development of a Full-Scale Retrofittable Ammonia Combustor for Can Annular Frame Engine Implementation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Low carbon and renewable fuels are an active area of research due to their potential to reduce both stack and life-cycle carbon emissions. Ammonia is one such fuel as it has storage, production, infrastructure, ...
Evaluation of Minimum NOx Emission From Ammonia Combustion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ammonia (NH3) is being explored as a hydrogen carrier with no carbon emissions. However, if burned directly as NH3, rather than being completely decomposed back to N2/H2, the fuel-bound nitrogen comes with a potentially ...
