Coal and wood co-fired boiler technology has been
significantly advancing in the past years, but many
of their capabilities remain unknown to much of the
industry today. The term "co-firing", when used by
members of the biomass or utility communities, has
come to mean mixing a modest amount of clean, dry
sawdust with coal and burning the sawdust coal
mixture in the existing coal firing equipment of a
large, coal-burning, utility boiler. This work serves
as a guideline to allow for coal-wood co-fired
boilers to be sized, priced, implemented, and
operated properly based on facility information.
Information about the equipment that is required for
the boiler replacement project is provided. This work
also recognizes energy savings that would be
available upon installation as compared to other
types of boilers. The energy savings that are
available as a result of implementing these types of
boilers present very significant cost savings.
