Operating Experience of the 20-MW AFBC Pilot Plant
Abstract
The Tennessee Valley Authority (TVA) took the
first major step toward utility-scale demonstration
of atmospheric fluidized bed combustion (AFBC) with
the construction and operation of the 20-MW AFBC
Pilot Plant. The pilot plant was built to bridge
the gap between the small process development units
and utility-scale demonstration plants. To date,
the pilot plant has operated successfully for over
20,000 hours in a test program cosponsored by the
Electric Power Research Institute. The purpose of
the test program was to address the technical
uncertainties associated with application of the
AFBC process for the utility industry. The test
program emphasized investigations of process
performance, coal and limestone feeding, system and
equipment reliability, and turndown and control
system development. The confidence that was gained
from the operation of the pilot plant has encouraged
TVA and others to move forward with utility-scale
demonstration of fluidized bed combustion. TVA's
operating experience at the 20-MW AFBC Pilot Plant
is discussed.
