“…Six fly ash samples, two blanks, and one control were cut into three or four pieces to check uniformity. Samples were analyzed at the Nuclear Radiation Center, Washington State University, by using INAA methods described previously (16,10). The samples from stages 23 through 27 and the blanks and controls were analyzed a second time because of the larger relative interference from the low concentrations of elements in the polyethylene bags in which the samples were originally sealed and analyzed.…”

“…from one of the studies (7,10), at the Kramer Station, may represent a lower limit of some sort since this boiler had the smallest submicrometer fume mass concentration of the six boilers on which our group made total submicrometer fume mass measurements (7).…”

“…On the basis of the accumulated literature on ozone chemistry, it can be postulated that the cyanide species, HCN and CN~, may react directly by molecular ozone, as well as by the hydroxyl radical, OH•, which may be prof Present address: Versar Inc., Springfield, VA 22151. duced upon hydroxide ion initiated decomposition of ozone (9), and as an intermediate product of the reaction of cyanide species with molecular ozone. The decomposition of ozone is strongly catalyzed by the hydroxide ion (10)(11)(12). Therefore, the rate of OH• formation, as well as cyanide speciation, is determined by the pH of water.…”

“…Typically, ESPs have a penetration window in the particle size range of 0.1-1 µm. In pulverized coal combustion, even 10% of the particles in this size range may penetrate the ESP (10)(11)(12). Fabric filter collection efficiency also decreases with decreasing particle size, but with a well-maintained fabric filter, the maximum penetration is typically significantly lower than with ESPs.…”

Particle and trace element emissions from energy production have continuously been subject to tightening regulations. At the same time, not enough is known on the effect of different combustion processes and different fuels and fuel mixtures on the particle characteristics and particle removal device operation. In this investigation, electrostatic precipitator fractional collection efficiency and trace metal emissions were determined experimentally at a 66 MW biomass-fueled bubbling fluidized-bed combustion plant. The measurements were carried out at the inlet and outlet of the two-field electrostatic precipitator (ESP) at the flue gas temperature of 130-150 degrees C. Two fuel mixtures were investigated: biomass fuel containing 70% wood residue and 30% peat and biomass with recovered fuel containing 70% wood residue, 18% peat, and 12% recovered fuel. The particle mass concentration at the ESP inlet was 510-1400 mg/Nm3. Particle emission at the ESP outlet was 2.3-6.4 mg/Nm3. Total ESP collection efficiency was 99.2-99.8%. Collection efficiency had a minimum in particle size range of 0.1-2 microm. In this size range, collection efficiency was 96-97%. The emission of the trace metals As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Sb, Tl, and V was well below the regulation values set by EU directive for waste incineration and co-incineration.

“…The baghouses evaluated encompassed a representative sampling of unit size, design, and fuels, and are listed in Table II. Data taken at the Nucla and Kramer stations reported by Ensor et al 4 ' 5 under earlier EPRI sponsorship are included in the table as well. Also, for comparison with these full-scale units, EPRFs two pilot baghouses-the lowsulfur coal fabric filter pilot plant (FFPP) at the Public Service Co. of Colorado's Arapahoe Station in Denver, and the high-sulfur coal fabric filter pilot plant (HSFP) at Gulf Power Co.'s Scholz station near Sneads, Floridaare included in the data base.…”

Performance of Full-Scale Utility Baghouses This is the third in a series of papers discussing the experience of electric utilities in applying baghouse technology for the collection of particulate matter at coal-fired electric power generating plants. The series presents new data obtained in research sponsored by the Electric Power Research Institute (EPRI) on reverse-gas and shake/deflate cleaned baghouses, and specifically addresses a number of unresolved issues in the design and operation of these units. This paper provides an overview of the design and operating characteristics of baghouses now in place in the utility industry. In addition, it discusses three key issues in design and operation: the relationships among dust cake weight and chemical composition, air-to-cloth ratio, and pressure drop; fabric selection; and bag life.
