Abstract
Foam is displacing wet suppression as the method
of choice for controlling fugitive emissions from
coal. Coal treated by wet suppression consumes
through moisture addition, a heat energy
equivalent of 1 ton out of every 500 tons fired.
The application of foam requires less than 10% of
the moisture usually required for wet
suppression. In addition, foam is a much more
effective dust suppressant, especially on
respirable dust (particle with an aerodynamic
diameter less than 10 microns). To achieve
maximum benefit from foam dust control, efficient
on-site production of dry, stable foam is
required. This paper discusses the basics of
foam production and the many variables affecting
foam expansion ratios. Successful applications
of foam are also described.
