Numerical Study on the Effect of Real Syngas Compositions on Ignition Delay Times and Laminar Flame Speeds at Gas Turbine Conditions

Source: Journal of Engineering for Gas Turbines and Power:;2014:;volume( 136 ):;issue: 001:;page 11502

Author(s): Mathieu, Olivier; Petersen, Eric L.; Heufer, Alexander; Donohoe, Nicola; Metcalfe, Wayne; Curran, Henry J.; Gأ¼the, Felix; Bourque, Gilles

Publisher: The American Society of Mechanical Engineers (ASME)

Abstract: Depending on the feedstock and the production method, the composition of syngas can include (in addition to H2 and CO) small hydrocarbons, diluents (CO2, water, and N2), and impurities (H2S, NH3, NOx, etc.). Despite this ...

Ignition Delay Time and Laminar Flame Speed Calculations for Natural Gas/Hydrogen Blends at Elevated Pressures
