Biomass Cofiring in Coal-Fired Boilers
Raymond Ehrhard, P.E.
Overview
Biomass energy technologies convert renewable
biomass fuels to heat or electricity. Biomass cofiring is attracting interest
because it is an economical near-term option for introducing new biomass
resources into today’s energy mix. Cofiring is the simultaneous combustion of
different fuels in the same boiler. Cofiring inexpensive biomass with fossil
fuels in existing boilers provides an opportunity for energy managers to use a
greenhouse gas-neutral renewable fuel while reducing energy and waste disposal
costs and enhancing national energy security.
To help the nation use more domestic fuels and
renewable energy technologies and increase our energy security, the Federal
Energy Management Program (FEMP) in the U.S. Department of Energy, Office of
Energy Efficiency and Renewable Energy, assists government agencies in
developing biomass energy projects. As part of that assistance, FEMP has
prepared this Federal Technology Alert on biomass cofiring technologies. This
publication was prepared to help federal energy and facility managers make
informed decisions about using biomass cofiring in existing coal-fired boilers
at their facilities. It is also helpful to other facilities that operate
municipal and industrial boilers.
This course is intended for engineers, state and
federal regulators, and energy professionals. It provides information on types
of biomass available and criteria used to co-fire in coal fired boilers. Along
with energy impacts, other implementation factors are presented using facility
studies and case examples. Costs and worksheets are given to provide energy and
economic analysis decisions.
The
student is expected to read and review the material contained in the US
Department of Energy, Energy Efficiency and Renewable Energy, Federal Technology
Alert, DOE/EE-0288, May 2004.
The student must take a multiple-choice quiz consisting of
twenty (20) questions at the end of this course to obtain 4 PDH credits.
