RISFlashback Prevention in a Hydrogen-Fueled Reheat Combustor by Water Injection Optimized With Global Sensitivity Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates water injection effects in a simplified Ansaldo GT36 reheat system under realistic conditions of 20 atm using large eddy simulation (LES) coupled with thickened flame modeling and adaptive mesh ...
Numerical Concept Study for Part-Load Operation of the Ansaldo Constant Pressure Sequential Combustion System Operated in Rich–Dilute–Lean Mode Using Ammonia-Based Gaseous Fuels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Two earlier concept studies, exploiting high-resolution numerical simulations, have shown that Ansaldo's constant pressure sequential combustor (CPSC) at full load is theoretically capable of switching from ...
Numerical Assessment of a Rich-Quench-Lean Staging Strategy for Clean and Efficient Combustion of Partially Decomposed Ammonia in the Constant Pressure Sequential Combustion System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a future energy system prospective, predictably dominated by (often) remote and (always) unsteady, nondispatchable renewable power generation from solar and wind resources, hydrogen (H2) and ammonia (NH3) have emerged ...
