Design and Operating Experience of Wet Electrostatic Precipitators Following Wet FGD’s:
For Sulfuric Acid Mist and Fine Particulate Control
PD Hours: 2 Viewing Format(s): PDF Fee: $59.00 Purchase / Take Exam

7

During fossil fuel combustion, most of the sulfur in the fuel reacts to produce sulfur dioxide (SO2). However, a small fraction further oxidizes to sulfur trioxide (SO3). Visually, SO3 will impart a blue coloration to the stack emissions, where the common term is known as the "blue plume." More seriously, SO3 will react with moisture in the atmosphere to produce sulfuric acid aerosols that cause low-level air pollution. This course outlines a mechanical technology, wet electrostatic precipitators (WESP), for reducing SO3 and fine particulate emissions from fossil-fired boilers.

Educational Objectives:
  1. Gain an understanding of the wet electrostatic precipitators and their operations at two electric power generating units.
  2. Understand the design and installation of the power plants' WESP systems.
  3. Understand the rationale for upgrading other WESP systems.
  4. Gain an understanding of test results related to the installations.

This course examines the fundamentals of an ash collection and recycling system installed on a 600 MW boiler.

Educational Objectives:
  1. Understand the design/sizing criteria for a pneumatic recycle ash conveying system.
  2. Understand the limits of traditional fly ash pneumatic conveying systems.

Oxy-Combustion: A Sound and Near Term Technology for CO2 Emissions Reduction – Development and Next Steps
Not Rated
PD Hours: 2 Viewing Format(s): PDF Fee: $59.00 Purchase / Take Exam

19

Coal makes up centuries’ worth of additional fossil fuel supplies around the globe. However, it is increasingly apparent that the continued use of coal will require tighter control of CO2 emissions. Underground sequestration will undoubtedly be part of the answer, but this brings forth another issue: capturing the CO2 from flue gas. Conventional combustion utilizes ambient air, but the air we breathe contains 78% nitrogen, which in turn comprises the bulk of the flue gas flow. Such large volumes require very large backend equipment for CO2 removal. A technology that is emerging is oxy-combustion, where the boiler is fired with pure oxygen combined with recycled flue gas, such that the flue gas is primarily CO2 with very little nitrogen. This course outlines important issues regarding this emerging technology.

Educational Objectives:
  1. Understand the difference between oxy-combusion and standard combustion techniques.
  2. Learn which types of boilers are best suited for oxy-combustion.
  3. Learn how oxy-combustion influences air emissions control.
  4. Understand modifications that must be made to steam generators to utilize oxy-combustion.
