In this study, system layouts for integrated gasification solid oxide fuel cell/gas turbine (IG-SOFC/GT) systems were proposed and their performance was comparatively evaluated. A baseline IGCC was simulated, and the calculation models were validated. Based on the IGCC system, two IG-SOFC/GT...

The increasing interest in the development of carbon capture and storage (CCS) technologies requires a great effort to reduce capital and operating costs and to demonstrate the potential application of these kind of systems on the commercial power generation plants.

Carbon capture and storage (CCS), when applied to biomass cofiring systems, can remove atmospheric CO2 since the CO2 that is consumed by the biomass during growth is not released back into the atmosphere. Biomass cofiring can also potentially contribute to meeting renewable portfolio standards...

A broadband, RGB, two-color pyrometry technique for measuring the flame temperature and total emissivity of a two-dimensional image of a coal flame has been developed and used on an oxy-coal flame. The method uses a single, relatively inexpensive, RGB, digital camera. The camera software permits...

This paper presents a detailed study on the effect of temperature on the concentration of 27 major and trace elements in bottom ash generated from oxy fuel-combustion. The major elements are Na, Mg, Al, K, Ca and Fe and the minor and trace elements are Li, Cr, V, Mn, Sr, Ba, Cu, Zn, Rb, Co, Ni,...

Support for carbon capture, utilization and storage (CCUS) for coal power plants is limited, to some extent, by the high cost of electricity associated with available technologies. While a comparison of different capture methods favors oxy-combustion technology, the cost is still prohibitively...

An experiment system made up of a membrane absorption unit and a membrane vacuum regeneration unit was set up. Ionic liquids (ILs), 1-butyl-3-methyl-imidazolium tetrafluoroborate ([bmim][BF4]) and 1-(3-aminopropyl)-3-methyl-imidazolium tetrafluoroborate ([apmim][BF4]) as two absorbents for CO2...

The objective of this work is to study the performance of the oxygen carrier in a packed bed with periodic switching between oxidizing and reducing conditions. In this paper the performance of CuO/Al2O3 as the oxygen carrier in a packed bed reactor with syngas as the fuel are investigated, while...

This work presents a CO2 sorbent that may be synthesized from low-cost and widely available materials following a simple method basically consisting of impregnation of a nanostructured silica support with a saturated solution of calcium nitrate. In a first impregnation stage, the use of a...

In spite of the rapid development and introduction of renewable and alternative resources, coal still continues to be the most significant fuel to meet the global electricity demand. Emission from existing coal based power plants is, besides others, identified as one of the major sources of...
