Particle-Size Distributions and Heavy Metal …

Emission measurements examined PM and gas emission concentrations, particle size distributions (PSDs), the partitioning of heavy metals, and the concentration of ultrafine particles. The facilities examined included two bituminous coal-fired power plants (pulverized coal combustors) and one anthracite coal-fired power plant (circulating fluidized bed combustor). Measurements were made at ...

Different boilers, coals, and PECDs are used in these power plants. Measurement in situ was performed by an electrical low-pressure impactor with a sampling system, which consisted of an isokinetic sampler probe, precut cyclone, and two-stage dilution system with a sample line to the instruments. The size distribution was measured over a range from 0.03 to 10 µm. Before and after all of the ...

Electrostatic precipitator - Wikipedia

Invention of the electrostatic precipitator. The first use of corona discharge to remove particles from an aerosol was by Hohlfeld in 1824. However, it was not commercialized until almost a century later. In 1907 Frederick Gardner Cottrell, a professor of chemistry at the University of California, Berkeley, applied for a patent on a device for charging particles and then collecting them ...
