Subtask 2.11 - An Investigation into the EERC Staged Electrostatic Precipitator Concept

PDF Version Also Available for Download.

Description

A new concept of electrostatic precipitator (ESP), named a Staged ESP (an Energy & Environmental Research Center proprietary), was conceived in June 2004. The concept is based on a simple design that can be retrofitted on existing coal-fired power plants to provide high particulate matter (PM) collection efficiency without compromising reliability. A prototype of Staged ESP was designed, fabricated, and tested in two different combustion coal flue gases with different fly ash resistivities. Several design parameters of the Staged ESP were evaluated under various operating conditions to optimize PM collection performance. A set of particulate sampling data, including aerodynamic particle ... continued below

Description

A new concept of electrostatic precipitator (ESP), named a Staged ESP (an Energy & Environmental Research Center proprietary), was conceived in June 2004. The concept is based on a simple design that can be retrofitted on existing coal-fired power plants to provide high particulate matter (PM) collection efficiency without compromising reliability. A prototype of Staged ESP was designed, fabricated, and tested in two different combustion coal flue gases with different fly ash resistivities. Several design parameters of the Staged ESP were evaluated under various operating conditions to optimize PM collection performance. A set of particulate sampling data, including aerodynamic particle sizer, scanning mobility particle sizer, and U.S. Environmental Protection Agency Method 5 data, was collected to determine PM emissions of the Staged ESP configurations. These data were compared against data collected with a conventional ESP configuration. Compared to PM capture performance in conventional ESPs, an additional 30% to 70% reductions on total PM emissions were achieved for Staged ESPs in flue gas with medium- to high-resistivity fly ashes. Experimental data proved that the Staged ESP concept is capable of achieving higher PM collection efficiency, especially for particles in the submicrometer size range typically thought difficult to capture in an ESP.
