Combustion of lean methane over Co3O4 catalysts prepared with different cobalt precursors

RSC Advances, 2020
To investigate the effect of catalyst precursors on physicochemical properties and activity of lean methane catalytic combustion, a series of Co3O4 catalysts were prepared via a precipitation method by using four different cobalt precursors: Co(C2H3O2)2,

Investigation into Lean-Burn Combustor Thermo-acoustic Instabilities: Modelling of Entropy Convection for Low Frequency Rumble Prediction [PDF]

New combustion methods, aimed to reduce emissions, are shown to be susceptible to instability. To reduce nitrogen oxides, the traditional diffusion flame is replaced by lean combustion, where fuel-air are partially premixed, and combustion conditions are

Large Eddy Simulation of combustion instabilities in a lean partially premixed swirled flame [PDF]

, 2012
This paper investigates one issue related to Large Eddy Simulations (LES) of self- excited combustion instabilities in gas-fueled swirled burners: the effects of incom- plete mixing between the gas injection and the combustion chamber.

Variation of turbulent burning rate of methane, methanol, and iso-octane air mixtures with equivalence ratio at elevated pressure [PDF]

, 2005
Turbulent burning velocities for premixed methane, methanol, and iso-octane/air mixtures have been experimentally determined for an rms turbulent velocity of 2 m/s and pressure of 0.5 MPa for a wide range of equivalence ratios. Turbulent burning velocity

Combustion regimes in sequential combustors: Flame propagation and autoignition at elevated temperature and pressure

, 2018
This numerical study investigates the combustion modes in the second stage of a sequential combustor at atmospheric and high pressure. The sequential burner (SB) features a mixing section with fuel injection into a hot vitiated crossflow.

A single-component water-lean post-combustion CO2 capture solvent with exceptionally low operational heat and total costs of capture – comprehensive experimental and theoretical evaluation

, 2020
A comprehensive evaluation of a recently developed water-lean amine-based solvent, namely N-(2-ethoxyethyl)-3-morpholinopropan-1-amine (2-EEMPA), has been performed to analyze its post-combustion CO2 capture performance.
