This paper reports an experimental investigation of the pollutant emission and noise radiation characteristics of both open and impinging inverse diffusion flames (IDFs), produced by five burners of different air port diameter (dair=5, 6 and 6.84mm) and air-to-fuel spacing (S=8, 11.5 and 15mm)....

We report a preliminary study that compared decisions made in an oxygen depleted environment with those made in a normoxic environment. Participants were presented with a series of choices that involved either losses or gains. For each choice they were forced to choose between a sure thing and a...

This paper is an experimental study on the heat transfer optimization of an Innovative Inverse Diffusion Flame (IDF) characterized by a central air jet surrounded by an array of fuel jets for impingement heating. It is found that the diameter ratio between air port and fuel port (da/df) exerts...

This paper is an experimental study on the combustion optimization of an Innovative Inverse Diffusion Flame (IDF) characterized by a central air jet surrounded by an array of fuel jets for impingement heating. An extensive investigation has been performed to explore the effects of the diameter...

An experimental study was performed to investigate the effects of the nozzle length on the air-pollutant-emission and noise-radiation behaviors of a burner utilizing a multi-fuel-jet inverse diffusion flame (MIDF). Comparison of the experimental results obtained from two MIDF burners, one with a...

The oxygen-enriched combustion of biomass micro fuel (BMF) was carried out respectively in the thermogravimetric analyzer and cyclone furnace to evaluate the effects of oxygen concentration on combustion performance. The experimental results show that with the increasing oxygen concentration,...

This study presents the effects of O2 enrichment and CO2 (carbon dioxide) dilution on laminar methane flames. For that purpose, the following procedure was followed: i) measurements of laminar methane flame velocities carried out in a stainless steel combustion chamber at atmospheric pressure...

Results are presented on the effects of oxygen enrichment on the performance of a flameless combustion furnace equipped with a regenerative burner. Natural gas was used as fuel (∼97% CH4) and the oxygen concentration in the combustion air was varied from 21% to 35% (volumetric percent). The...

The energy efficiency of the separation of air into an oxygen-enriched permeate and an oxygen-depleted residue stream in a polymeric hollow fiber membrane module is studied. On the basis of the modeled performance of the module, three different counter-current lumen-feed flow system...

In this research oxygen enrichment, gasoline pilot port injection, and delayed time of 50% cumulative heat release (CA50) are evaluated to expand the range for stable and safe combustion of a lean-burning biogas-fueled HCCI engine. A 4-cylinder 1.9L Volkswagen TDI engine was modified to run in...
