“…They reported that the inter‐diffusion model is more successful in predicting the experimental data, as it assumes that more volatile component of the fuel firstly vaporizes out of the droplet surface while the internal composition remains same. Kamal and Mohamad investigated the combustion characteristics of liquid fuel in a cross‐flow swirl combustor. They found that introducing the swirl resulted in mixing enhancement which consequently increased the reaction kinetics and significantly reduced the formation of NO x and CO.…”

Summary The increased level of emissions of carbon dioxide into the atmosphere due to burning of fossil fuels represents one of the main barriers toward the reduction of greenhouse gases and the control of global warming. In the last decades, the use of renewable and clean sources of energies such as solar and wind energies has been increased extensively. However, due to the tremendously increasing world energy demand, fossil fuels would continue in use for decades which necessitates the integration of carbon capture technologies (CCTs) in power plants. These technologies include oxycombustion, pre‐combustion, and post‐combustion carbon capture. Oxycombustion technology is one of the most promising carbon capture technologies as it can be applied with slight modifications to existing power plants or to new power plants. In this technology, fuel is burned using an oxidizer mixture of pure oxygen plus recycled exhaust gases (consists mainly of CO2). The oxycombustion process results in highly CO2‐concentrated exhaust gases, which facilitates the capture process of CO2 after H2O condensation. The captured CO2 can be used for industrial applications or can be sequestrated. The current work reviews the current status of oxycombustion technology and its applications in existing conventional combustion systems (including gas turbines and boilers) and novel oxygen transport reactors (OTRs). The review starts with an introduction to the available CCTs with emphasis on their different applications and limitations of use, followed by a review on oxycombustion applications in different combustion systems utilizing gaseous, liquid, and coal fuels. The current status and technology readiness level of oxycombustion technology is discussed. The novel application of oxycombustion technology in OTRs is analyzed in some details. The analyses of OTRs include oxygen permeation technique, fabrication of oxygen transport membranes (OTMs), calculation of oxygen permeation flux, and coupling between oxygen separation and oxycombustion of fuel within the same unit called OTR. The oxycombustion process inside OTR is analyzed considering coal and gaseous fuels. The future trends of oxycombustion technology are itemized and discussed in details in the present study including: (i) ITMs for syngas production; (ii) combustion utilizing liquid fuels in OTRs; (iii) oxy‐combustion integrated power plants and (iv) third generation technologies for CO2 capture. Techno‐economic analysis of oxycombustion integrated systems is also discussed trying to assess the future prospects of this technology. Copyright © 2017 John Wiley & Sons, Ltd.

“…An experimental investigation of liquid fuel combustion on a cross-flow swirl burner was carried out by Kamal and Mohamad [10]. They found that the CO and NO, emissions are significantly reduced by the introduction of swirl which enhances the mixing and results in an increase of kinetics rates.…”

Study of C o m b u stio n C h a ra c te ris tic s of Ethanol at D iffe re n t D ilu tio n W ith the C a rrie r GasWith the ever-rising concern o f global warming, carbon capture is gaining the reputation of one of the most challenging fields o f research. A very promising technology to capture C 0 2 is oxy-combustion. Oxy-combustion offers several advantages over conventional combustion technologies, such as flue-gas volume reduction, high combustion efficiency, low fuel consumption, and significant reduction in NO, emissions. Liquid fuel is available and it is the most widely used source o f energy in the world. Easy handling and transport ing, less storage volume and higher flame temperature are some o f the features o f liquid fuel which give it an upper hand over other sources. In this study, an experimental work on oxygen enriched combustion o f ethanol in a vertical reactor by Lucas et at. (2005,
