In order to design ITM-based oxy-combustion power cycles, various reactor engineering analyses must be conducted with detailed modeling and simulation. An intermediate-fidelity ITM model is used to explore the dependence of ITM performance on reactor geometric structure, flow configuration,...

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...

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...

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...

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...

Oxy-combustion is a competitive technology to capture CO2. Current air separation technologies for high volume O2 production are based on cryogenic distillation. When a double-column distillation cycle is applied to produce O2 with a purity of 95 mol%, the oxygen production process is causing...

The supercritical power plant analyzed in this paper consists of the following elements: a steam turbine, a hard-coal-fired oxy-type pulverized fuel boiler, an air separation unit with a four-end-type high-temperature membrane and a carbon dioxide capture unit. The electrical power of the steam...

A scale of 2.4MW molten carbonate fuel cell (MCFC) was taken to construct a high-efficiency and economic power generation system without CO2 emission for utilizing its exhaust gas. A conventional steam turbine power generation system (STPS) is evaluated and the net generated power (NGP) is...

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,...
