ABSTRACT: A Better Alternative to SO₃ for conditioning Electrostatic Precipitators

Using SO₃ to condition the flue gas of boilers burning low-sulfur coal is going to face a new challenge: Mercury control, since SO₃ inhibits the mercury removal by either fly ash or powdered activated carbon (PAC).  A better alternative is to inject trona into flue gas upstream of hot-side or cold-side ESP.  It can lower the resistivity of fly ash and solve the problem of back corona due to “sodium depletion” of hot-side ESP_.  In addition, the added trona can remove SO₃ and thus improve the mercury removal.  The trona addition system is simple and its capital cost is much lower than that of SO₃ production and injection system.

Title:  “Wet ESPs for Particulate Control Enhancement from Utility Boilers”

ABSTRACT:  New emission control rules that are expected from the US EPA will put increasing pressure on utility-boiler operators.   Wet electrostatic precipitator technology is a logical add-on alternative to help meet these rules.  This is particularly true if boiler emissions are already being treated with wet a FGD.  This presentation will explore the pros and cons of wet ESPs in the utility environment with an emphasis on retrofit issues .

PAUL LEANZA – POLLUTION CONTROL SERVICES, INC.

BIO: Paul is the Senior Technical Engineer for Post Combustion Control Equipment, with Pollution Control Services, Inc.  PCS was started in 1998 to provide experienced on-site consultant services for Wet-FGD Scrubbers, WESP, ESP, Baghouse, SCR and Dry Injection Systems.  Paul started with Forry, Inc in 1988, which was a major supplier of precipitator automatic voltage and rapper controls.  Paul also worked for Southern Environmental, Inc and TRK Engineering prior to joining PCS in 2002.

ABSTRACT: This presentation will focus on evaluating existing precipitators’ ability to meet the future PM_2.5 regulations.  The majority of existing ESP’s are not operating under their original design basis. Many existing ESPs have not been upgraded with modern operating philosophies or equipment. Taking a holistic approach in evaluating the precipitator in its current operating parameters permit a viable plan forward as the operating parameters have been modified as additional post combustion control equipment like SO₃, NO_x, and Hg control have been incorporated over the last few years.

C. JEAN BUSTARD – ADA-ES, INC.

ABSTRACT: C. Jean Bustard, COO at ADA-ES, Inc., will present information on an alternative to SO₃ for flue gas conditioning.  SO₃ is widely used to improve the performance of ESPs on units firing lower sulfur fuels.  Unfortunately, SO₃ impacts the effectiveness of activated carbon for mercury control.  ADA offers an alternative to SO₃ for flue gas conditioning that does not impact activated carbon.  This presentation will include an overview of the technology, results, and photos of the equipment.
