Combustion kinetics of coal chars in oxygen-enriched environments
Oxygen-enhanced and oxygen-fired pulverized coal combustion is actively being investigated to achieve emission reductions and reductions in flue gas cleanup costs, as well as for coal-bed methane and enhanced oil recovery applications. To fully understand the results of pilot scale tests and to accurately predict scale-up performance through CFD modeling, accurate rate expressions are needed to...
متن کاملPerformance characterization of a pilot-scale oxygen enriched-air and steam blown gasification and combustion system
The use of air as biomass gasifying agent yields low heating value product gas and is only suitable for heat and power applications. Steam and oxygen gasification on the other hand can increase gas heating value as well as main gas constituents suitable for production of liquid fuels through synthesis processes. Experiments were carried out to investigate the influence of using oxygen enriched-...
متن کاملInvestigation of the uptake ability of fly ashes produced after lignite combustion.
Fly ash samples from the five steam electric power stations of the Lignite Center of Western Macedonia were used in this study. They consisted mainly of anhydrite, lime, quartz and amorphous material as well as feldspars, calcite, micas + clays, portlandite and gehlenite which were all present in minor amounts. Anhydrite, lime and portlandite in the fly ash samples diminished upon treatment wit...
متن کاملEffect of Using Oxygen-Enriched Gas during Induration Process of Iron Ore Pellets Containing Solid Fuel
In this research, the effects of oxygen injection during the induration process were studied in order to improve the quality specifications and increase the rate of production of the iron oxide pellets. Several experiments were carried out in palletizing pilot plant in different conditions of oxygen injection. The results suggested that if only the extra oxygen was injected into the furnace in ...
متن کاملQuantitative Measurement of Oxygen in Microgravity Combustion
A low-gravity environment, in space or in ground-based facilities such as drop towers, provides a unique setting for studying combustion mechanisms. Understanding the physical phenomena controlling the ignition and spread of flames in microgravity has importance for space safety as well as for better characterization of dynamical and chemical combustion processes which are normally masked by bu...
