Characterization of the particulate emission by a large oil fuel fired power plant

Morphologie und Mineralogie der Flugasche von einem Kohlekraftwerk

“…2b). The latter, on the basis of a simple external examination of their shape and superficial features, are similar to those recognized as typical of oil-fuel combustion emission [9][10][11]. Ele-7* Fig.…”

Control of Toxic Metal Emissions from Combustors Using Sorbents: A Review

“…Coal, municipal solid waste, and municipal waste sludge tend to have most of the targeted (in the 1990 CAAA) trace metals in their matrix. Fuel oils tend to contain nickel, vanadium, and several alkali and alkaline earth metals 28,29 in their matrix and are normally present or bound organically. Aviation fuels are refined and consist of the lighter fractions of the organics.…”

Primary and Secondary Sources of Atmospheric Aerosol

“…These images present a characterization of combustion particles (Hobbs, 2000) 26 (Hobbs, 2000), 45 (Tsigaridis et al, 2006) 12 (Hobbs, 2000) 23 (Hobbs, 2000) 14.2 (IPCC, 2001) 21.3 (Liao et al, 2004) 44.1 (Tsigaridis et al, 2006) Carbonaceous aerosols from biomass burning (sizes < 2 μm) Carbonaceous aerosols from fossil fuel (sizes < 2 μm) Fossil fuel organic matter (sizes < 2 μm) Biomass burning black carbon (sizes < 2 μm) Anthropogenic organic compounds Carbonaceous aerosols from aircraft Industrial dust, etc. Total (natural + anthropogenic) 6315 (IPCC, 2001) sampled in the Po Valley (Italy) area, as emitted by an oil fuel-fired power plant (Bacci et al, 1983), a coal-fueled power plant (Del Monte and Sabbioni, 1984), and a domestic heating unit fueled by distilled oil (Sabbioni and Zappia, 1992). An analysis of these samples indicated that (a) oil-fired aerosol particles have spherical shapes presenting a porous surface, internal cavities, and a spongy structure, as can be seen in Figure 1.11a and b, which often contain sodium and vanadium oxide hydrate crystals having prismatic shapes and presenting relatively high elemental concentrations for all size classes over the 0.01-50 μm range (mainly with traces of Na, Al, Mg, S, K, V, Fe, Ni, Cu, Zn, and Pb elements); (b) fly ash particles emitted by a coal-fired power plant, such as that shown in Figure 1.11c, which may include different components of particulate matter, such as (i) glassy aluminosilicates of variable composition, (ii) spongy carbonaceous matter, (iii) spherical metallic particles containing different iron oxide phases (magnetite, hematite, maghemite), (iv) spherical rutile particles, (v) spherical lime particles, and (vi) mineral formless particles, containing mainly quartz and mullite; and (c) particles generated by domestic heating units fueled by distilled oil exhibit different morphological typologies (irregular, rounded to spherical, spherical with circular pores, smooth spherical particles, and spherical agglomerated particles, as presented in the example of Figure 1.11d); they often host crystals with different structural shapes, such as "rosettes" composed of twinned crystals with hexagonal habit or elongated crystals, in which the elemental composition is mainly given by S, Fe, Pb, Ti, V, Mn, Cu, Zn, Cd, Ni, Co, Ca, Si, and Cr.…”
