 Project Summary
 Pulverized Coal  Combustion:
 Pollutant  Formation  and Control,
 1970-1980
 Paul M. Lemieux
  The U.S. Environmental Protection
Agency (EPA) directed  a  major
research effort during the 1970s to
understand  pollutant  formation
during  pulverized coal combustion.
Understanding the conversion of fuel
nitrogen to nitrogen oxides (NOX) is
important, since changes  in the
combustion process designed to
control  NOX emission  may also
influence the formation  of  soot,
polycyclic aromatic hydrocarbons
(PAHs), and unburned carbon, and
the  vaporization of  inorganic
constituents. In addition, reduction of
sulfur oxides while maintaining low
NOX levels is also important.
  This Project  Summary was
developed by EPA's Air and  Energy
Engineering  Research Laboratory,
Research  Triangle  Park, NC,  to
announce key findings of the research
project that is fully documented in a
separate report of the same title (see
Project Report ordering information at
back).

Organization
  The full report details the research that
was  supported by the  Combustion
Research  Branch of  EPA's Air and
Energy Engineering Research Laboratory
during the 1970s. It is  a detailed
monograph, written by 19  coauthors,
containing sections on:
• The High Temperature Decomposition
  and Combustion of Pulverized Coal.

• Characterization of  Coal and Coal
  Thermal Decomposition.

• The Fate of Fuel Nitrogen and Ash
  During Combustion of Pulverized Coal
  Particles.

• Kinetic Modeling  of  Gas-Phase
  Chemistry  in  Coal   Volatiles
  Combustion.

• Soot and  PAH  Formation  in Coal
  Combustion.

• The Combustion Rates of Pulverized
  Coal Char Particles.

• Reduction  of  Nitric  Oxide by Solid
  Particles.

• Bench-S ale  Experiments  on the
  Formation and  Control of NOX
  Emissions  from Pulverized-Coal
  Combustion.

• Optimization of  Burner/Combustion-
  Chamber Design to Minimize NOX
  Formation During Pulverized Coal
  Combustion.
