Fundamental mechanisms in flue gas conditioning

Description: This project is divided into four tasks. Task 1 is the Development of a Management Plan. Task 2, Evaluation of Mechanisms in FGD Sorbent and Ash Interactions, focuses on the characteristics of binary mixtures of these distinct powders. Task 3, Evaluation of Mechanisms in Conditioning Agents and Ash, is designed to examine the effects of various conditioning agents on fine ash particles to determine the mechanisms by which these agents alter the physical properties of the ash. Tasks 2 and 3 bega… more

Fundamental mechanisms in flue gas conditioning. Quarterly report, July 1992--September 1993

Description: As suggested by our literature review, our data indicate that water adsorption depends on particle morphology and surface chemistry. Our recent laboratory efforts were directed primarily toward the determination of the effects of adsorbed water on the tensile and cohesive strengths of powders, and the conditioning of powders and ashes with SO{sub 3} and organosiloxane. Details of these conditioning methods are discussed under section 3.5.

Fundamental mechanisms in flue gas conditioning. Quarterly report, April 1993--June 1993

Description: The experiments we have been performing are primarily designed to define the extent to which water affects key properties of ashes, powders, and mixtures of sorbents and ashes. We have included selected data from prior quarterly reports in this report for the sake of completeness, and for comparisons with newly-acquired data. In several places in this report samples are referred to by their identification (SID) numbers. Table I provides a brief description of all the samples we have used in thi… more

Fundamental mechanisms in flue gas conditioning. Quarterly report, January 1994--March 1994

Description: We are currently performing a series of pilot-scale tests designed to determine the effects that adsorbed water has on fabric filtration and electrostatic precipitation of entrained fly ash particles in actual flue gas environments. We are investigating two key phenomena in our pilot-scale tests. The first is the ability of flue gas humidification to increase ash cohesivity through the creation of liquid bridges between particles collected in a fabric filter. Increasing cohesivity through the d… more

Fundamental mechanisms in flue gas conditioning

Description: The overall goal of this research project is to formulate a mathematical model of flue gas conditioning. This model will be based on an understanding of why ask properties, such as cohesivity and resistivity, are changed by conditioning. Such a model could serve as a component of the performance models of particulate control devices where flue gas conditioning is used. There are two specific objectives of this research project, which divide the planned research into two main parts. One part of … more

Fundamental mechanisms in flue gas conditioning

Description: We performed a wide variety of laboratory analyses during the past quarter. As with most of the work we performed during the previous quarter, our recent efforts were primarily directed toward the determination of the effects of adsorbed water on the cohesivity and tensile strength of powders. We also continued our analyses of dust cake ashes that have had the soluble compounds leached from their particle surfaces by repeated washings with water. Our analyses of leached and unleached dust cake … more

Fundamental mechanisms in flue gas conditioning. Quarterly report, January 1993--March 1993

Description: Our recent laboratory efforts were primarily directed toward the determination of the effects of adsorbed water on the tensile strength of powders and the development of apparatus for Experiment 3.5. As suggested by our literature review, our data indicate that water adsorption depends on particle morphology and on surface chemistry. Our measurements of tensile strength show that, for many of the samples we have analyzed, a relative minimum in tensile strength exists for samples conditioned and… more

Fundamental mechanisms in flue gas conditioning

Description: SEM pictures of the three mixtures of sorbent and ash from the DITF and the base line ESP hopper ash from Muskingum are shown in Figures 1 through 4. The effects of sorbent addition on particle morphology are evident in Figures 2 through 4 by the presence of irregularly shaped particles and deposits on the surfaces of the spherical fly ash particles. In contrast, the base Ene ash particles have the characteristic relatively smooth, spherical morphology normally associated with pulverized-coal (… more

Particulate hot gas stream cleanup technical issues

Description: The analyses of hot gas stream cleanup particulate samples and descriptions of filter performance studied under this contract were designed to address problems with filter operation that have been linked to characteristics of the collected particulate matter. One objective of this work was to generate an interactive, computerized data bank of the key physical and chemical characteristics of ash and char collected from operating advanced particle filters and to relate these characteristics to th… more

Analyses of ashes from the Tidd PFBC advanced particulate filter

Description: Early observations of the Advanced Particulate Filter (APF) at the Tidd PFBC Demonstration Plant led to the conclusion that tenacious ash deposits formed in the filter vessel and induced stresses that resulted in bent or broken ceramic candle filter elements. The proximity of these bent and broken candle filter elements to large, strong ash deposits emphasized the need to prevent or control the growth of these deposits, facilitate their on-line removal, and/or to develop filter design criteria … more

Characterization and modification of particulate properties to enhance filtration performance

Description: This report describes the results of project activities that occurred during the period from March 1 through May 31, 1989. The organization of this report generally follows the outline of work presented in the Project Work Plan. Work performed during this period included tests under Task 2 -- Parametric Tests of Ashes and Fabrics, and Task 3 -- Survey of Methods to Modify Particle Filtration Properties. Discussion of the Task 2 work has been organized topically, rather than adhering to the acti… more

Fundamental mechanisms in flue gas conditioning. Final report

Description: The US Department of Energy`s Pittsburgh Energy Technology Center (DOE/PETC) initiated this project as part of a program to study the control of fine particles from coal combustion. Our project focus was flue gas conditioning. Various conditioning processes have lowered operating costs and increased collection efficiency at utility particulate control devices. By improving fine particle collection, flue gas conditioning also helps to control the emission of toxic metals, which are concentrated … more
