Book excerpt: The target species to be analyzed in the DCM extracts are nitrated-PAH, hydroxylated-NO2-aromatic PAH (OH-NO2-AR/PAH), and PAH derivatives containing either a sulfur (PASH), nitrogen (PANH) or oxygen (oxy-PAH) (see Procedure 02 in the Appendix). Battelle recommends that extracts from particle size ranges A and B for both HD and LD samples be combined together for analysis. This combination will provide a sample quantity of 2.73 mg (0.88 + 0.96 + 0.48 + 0.40, from Table 6) to begin the fractionation into polarity classes. By combining the extracts in this manner it will not be possible to develop data differentiated by (1) particle size within the two size classes or (2) coal firing rate. The overriding factor, in Battelle's opinion, is that without combining the four extracts into one, it is likely that measurements of most of the target species will result primarily in nondetectable results because of the small concentrations of these species in the samples combined with the small quantity of sample. Battelle believes that it is most important to obtain measurable results for the species to guide the planning effort for the power plant study in the summer of 1993. The best opportunity to accomplish this goal for these difficult to measure species is by working with as much material as possible. Two other considerations are that there will still be differentiation of results by particle size for size range C versus the combined A+B. Also, results for PAH and other analytes (not reported herein) suggest that the differences in samples between the two coal firing rates may not be significant. Both of these considerations support Battelle's recommendation to combine the extracts according to the scheme cited above.

This book was released on 1993 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laboratory combustor studies were conducted at Battelle in the fall of 1992 to evaluate sampling methods and analysis techniques for air toxics generated by buming pulverized coal. These experiments were described in the fifth quarterly progress report. In this report results from additional analyses of samples are reported. Results are shown in Tables 1--8 for analysis of nitro-polycyclic aromatic hydrocarbons (nitro-PAH), oxygenated PAH (oxy-PAH), hydroxy-nitro-aromatic compounds (OH-NO2-AR/PAH), and PAH derivatives containing sulfur (PASH) and nitrogen (PANH). In the tables the two fning rates refer to the rate at which coal was fired in the laboratory fumace. The high firing rate was 5.7 g/s (45 lbs/hr), and the low firing rate was 5.3 g/s. The first letter in the sample identification refers to high (H) or low (L) coal firing rate. The second letter refers to either the hot flue samples (H) or samples collected with a Plume Simulating Dilution Sampler (D). The third letter refers to the particle size range. Size range A was about 3.3-7.1 [mu]m. Size range B was about 0.87-3.3 Jim. Size range C was less than 0.87-3.3[mu]m. Size range C was less than 0.87[mu]m. The nitro-PAH data from the hot flue and PSDS vapor and particle samples are summarized in Tables 1 through 4. The data on oxy-PAH, N02-OH-AR/PAH, PASH, and PANH from the PSDS particle samples are given in Tables 5 through 8, respectively. The most abundant target oxyPAH is fluorenone. Higher concentrations were found in size C samples as compared to the size A and size B composite samples. A similar relative concentration trend was also observed for other PAH derivatives.

Available in PDF, EPUB and Kindle. Book excerpt: Emissions of hazardous air pollutants from coal combustion were studied in a laboratory-scale combustion facility, with emphasis on fine particles in three size ranges of less than 7.5[mu]m diameter. Vapors were also measured. Substances under study included organic compounds, anions, elements, and radionuclides. Fly ash was generated by firing a bituminous coal in a combuster for 40 h at each of two coal feed rates. Flue gas was sampled under two conditions. Results for organic compounds, anions, and elements show a dependence on particle size consistent with published power plant data. Accumulation of material onto surface layers was inferred from differences in chemical composition between the plume simulating dilution sampler and hot flue samples. Extracts of organic particulate material were fractionated into different polarity fractions and analyzed by GC/MS. In Phase II, these laboratory results will be compared to emissions from a full-scale power plant burning the same coal.

This book was released on 1997 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: To help meet the requirements of the 1990 Clean Air Act Amendments, the U.S. Department of Energy (DOE) sponsored Phase I of a study entitled 'Comprehensive Characterization of Toxic Emissions from Coal-Fired Power Plants' in 1992. Final reports which detail air toxic emissions from eight power plants (nine configurations) have been completed by the contractors. The University of North Dakota Energy & Environmental Research Center (EERC) served as an independent third-party reviewer of these reports. In addition, the EERC has prepared two reports. The first report is a summary and evaluation of the stack emissions, entitled 'A Comprehensive Assessment of Toxic Emissions from Coal-Fired Power Plants: Phase I Results from the U.S. Department of Energy Study, ' of which a draft has been submitted to DOE and the individual contractors for input. All review comments were received as of January 1996 and are currently being incorporated into the final report. The second report, entitled 'A Comprehensive Assessment of Toxic Emissions from Coal- Fired Power Plants: Statistical Correlations from the Combined DOE and EPRI Field Test Data', prepared by the EERC details empirical correlations derived from the Phase I DOE data and the Electric Power Research Institute (EPRI) PISCES (Power Plant Integrated Systems: Chemical Emissions Studies) data. Review comments from the contractors and DOE have been received and responses prepared. Further work on the statistical correlations report is on hold until Phase II data are available to be incorporated.

Book excerpt: The Clean Air Act Amendments of 1990 identify a number of hazardous air pollutants (HAPs) as candidates for regulation. Should regulations be imposed on HAP emissions from coal-fired power plants, a sound understanding of the fundamental principles controlling the formation and partitioning of toxic species during coal combustion will be needed. With support from the Federal Energy Technology Center (FETC), the Electric Power Research Institute, the Lignite Research Council, and VTT (Finland), Physical Sciences Inc. (PSI) has teamed with researchers from USGS, MIT, the University of Arizona (UA), the University of Kentucky (UK), the University of Connecticut (UC), the University of Utah (UU) and the University of North Dakota Energy and Environmental Research Center (EERC) to develop a broadly applicable emissions model useful to regulators and utility planners. The new Toxics Partitioning Engineering Model (ToPEM) will be applicable to all combustion conditions including new fuels and coal blends, low-NO combustion systems, and new power generation x plants. Development of ToPEM will be based on PSI's existing Engineering Model for Ash Formation (EMAF). This report covers the reporting period from 1 July 1998 through 30 September 1998. During this period distribution of all three Phase II coals was completed. Standard analyses for the whole coal samples were also completed. Mössbauer analysis of all project coals and fractions received to date has been completed in order to obtain details of the iron mineralogy. The analyses of arsenic XAFS data for two of the project coals and for some high arsenic coals have been completed. Duplicate splits of the Ohio 5,6,7 and North Dakota lignite samples were taken through all four steps of the selective leaching procedure. Leaching analysis of the Wyodak coal has recently commenced. Preparation of polished coal/epoxy pellets for probe/SEM studies is underway. Some exploratory mercury LIII XAFS work was carried out during August at the Advanced Photon Source (APS), the new synchrotron facility at Argonne National Laboratory, Chicago, IL. Further analysis of small-scale combustion experiments conducted at PSI in Phase I was completed this quarter. The results of these experiments for the first time suggest almost complete vaporization of certain trace elements (Se, Zn) from coal combustion in the flame zone, in accordance with theoretical equilibrium predictions. Other elements (As, Sb, Cr) appeared considerably less volatile and may react with constituents in the bulk ash at combustion temperatures. The combustion section of the University of Arizona's Downflow Combustor was completely rebuilt. The University of Utah worked on setting up EPA Method 26A to give the capability to measure chlorine in flue gas. The chlorine kinetic calculations performed as part of the Phase I program were found to have an error in the initial conditions. Therefore, the calculations were re-done this quarter with the correct starting conditions. Development of a quasi-empirical emissions model based on reported emissions of particulate matter from field measurements was continued this quarter. As a first step in developing the ToPEM, we developed a sub-model that calculates the evaporation of major elements (Na, K, Fe, Si, Al, Ca and Mg) from both inherent and extraneous minerals of coal. During this quarter, this sub-model was included into EMAF, which formed the ToPEM. Experimental data from the Phase I program were used to test and modify the sub-model and the ToPEM.

This book was released on 1996 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before electric utilities can plan or implement emissions minimization strategies for hazardous pollutants, they must have an accurate and site-specific means of predicting emissions in all effluent streams for the broad range of fuels and operating conditions commonly utilized. Development of a broadly applicable emissions model useful to utility planners first requires a sound understanding of the fundamental principles controlling the formation and partitioning of toxic species during coal combustion (specifically in Phase I, As, Se, Cr, and possibly Hg). PSI Technologies (PSIT) and its team members will achieve this objective through the development of an {open_quotes}Engineering Model{close_quotes} that accurately predicts the formation and partitioning of toxic species as a result of coal combustion. The {open_quotes}Toxics Partitioning Engineering Model{close_quotes} (ToPEM) will be applicable to all conditions including new fuels or blends, low-NO(subscript x) combustion systems, and new power systems being advanced by DOE in the Combustion 2000 program. This report describes the mineralogy and chemical analysis of bituminous coal samples.

This book was released on 1995 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Babcock and Wilcox (B and W) is conducting a five-year project aimed at the development of practical, cost-effective strategies for reducing the emissions of hazardous air pollutants (commonly called air toxics) from coal-fired electric utility plants. The need for air toxic emissions controls will likely arise as the US Environmental Protection Agency proceeds with implementation of Title III of the Clean Air Act Amendments of 1990. Data generated during the program will provide utilities with the technical and economic information necessary to reliably evaluate various air toxics emissions compliance options such as fuel switching, coal cleaning, and flue gas treatment. The development work is being carried out using B and W's new Clean Environment Development Facility (CEDF) wherein air toxics emissions control strategies can be developed under controlled conditions, and with proven predictability to commercial systems. Tests conducted in the CEDF will provide high quality, repeatable, comparable data over a wide range of coal properties, operating conditions, and emissions control systems. The specific objectives of the project are to: (1) measure and understand the production and partitioning of air toxics species for a variety of steam coals, (2) optimize the air toxics removal performance of conventional flue gas cleanup systems (ESPs, baghouses, scrubbers), (3) develop advanced air toxics emissions control concepts, (4) develop and validate air toxics emissions measurement and monitoring techniques, and (5) establish a comprehensive, self-consistent air toxics data library. Development work is currently concentrated on the capture of mercury, fine particulate, and a variety of inorganic species such as the acid gases (hydrogen chloride, hydrogen fluoride, etc.).
