Fundamental studies of passivity and passivity breakdown (open access)

Fundamental studies of passivity and passivity breakdown

Effects of minor alloying elements on passivity breakdown and of photo effects on the properties of passive films are under study, and electrochemical and photoelectrochemical techniques are being used to explore transport and kinetic properties of vacancies and charge carriers in films and at metal/film and film/solution interfaces. Point defect and solute/vacancy interaction models are being developed to account for distributions in critical voltage and induction time for passivity breakdown by incorporating thermodynamics of absorption of halide ions into surface oxygen vacancies, by invoking different mechanisms for cation vacancy generation at film/solution interface, by extending the models to passive films on metal substrates having variable cation oxidation states, and by deriving rate laws for growth of passive films in response to an imposed voltage perturbation.

Integrated low emissions cleanup system for direct coal fueled turbines (moving bed, fluid bed contactor/ceramic filter) (open access)

Integrated low emissions cleanup system for direct coal fueled turbines (moving bed, fluid bed contactor/ceramic filter)

The United States Department of Energy, Morgantown Energy Research Center (DOE/METC), is sponsoring the development of direct coal-fired turbine power plants as part of their Heat Engines program. A major technical challenge remaining for the development of the direct coal-fired turbine is high-temperature combustion gas cleaning to meet environmental standards for sulfur oxides and particulate emissions, as well as to provide acceptable turbine life. The Westinghouse Electric Corporation, Science Technology Center, is evaluating two Integrated Low Emissions Cleanup (ILEC) concepts that have been configured to meet this technical challenge: a baseline ceramic barrier filter nEC concept, and a fluidized bed ILEC concept. These ILEC concepts simultaneously control sulfur, particulate, and alkali contaminants in the high-pressure combustion gases at turbine inlet temperatures up to 2300[degrees]F. This document reports the status of a program in the eighteenth quarter to develop this ILEC technology for direct coal-fired turbine power plants.

Scaleup tests and supporting research for the development of duct injection technology (open access)

Scaleup tests and supporting research for the development of duct injection technology

This Topical Report No. 2 is an interim report on the Duct Injection Test Facility being operated for the Department of Energy at Beverly, Ohio. Either dry calcium hydroxide or an aqueous slurry of calcium hydroxide (prepared by slaking quicklime) is injected into a slipstream of flue gas to achieve partial removal of SO{sub 2} from a coal-burning power station. Water injected with the slurry or injected separately from the dry sorbents cools the flue gas and increases the water vapor content of the gas. The addition of water, either in the slurry or in a separate spray, makes the extent of reaction between the sorbent and the SO{sub 2} more complete; the presumption is that water is effective in the liquid state, when it is able to wet the sorbent particles physically, and not especially effective in the vapor state. An electrostatic precipitator collects the combination of suspended solids (fly ash from the boiler and sorbent from the duct injection process). All of the operations are being carried out on the scale of approximately 50,000 acfm of flue gas.
