Influence of Particle Size, Moisture, and Cloud Density on Wood Dust Ignition

Chemie Ingenieur Technik, EarlyView.
The ignition and combustion of particle clouds are strongly affected by particle interactions. This study uses spectroscopy to examine effects of particle size, water content, and cloud density. Results show ignition delay rises with larger size and density, whereas combustion duration depends mainly on water and density due to moisture‐driven ...

Effect of different flue gas recirculation rates on low‐NOx combustion characteristics: A numerical simulation based on the combustion process of a gas boiler

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract NOx emissions from gas boilers severely impact the environment, and flue gas recirculation (FGR) technology can effectively reduce such emissions, yet the effects of different FGR rates on combustion performance and NOx formation remain unclear. This study thus used numerical simulation (via ANSYS Fluent, adopting the realizable k‐ε turbulence

Electrostatic Probe Measurements in Propagating Flames : Part 2, The Relation between Flame Propagation Velocity and Ion Current

Bulletin of JSME, 1977
An experimental study has been made on electrostatic probe measurements in flames propagating through a stoichiometric propane-air mixture in a tube in the initial pressure range from 200 to 500 mm Hg. The ion current records obtained by an electrostatic probe were examined in detail and were compared with the flame behavior recorded on the schlieren ...
