Enhancements for Competitive Coal-Fired Boiler Systems” (Technical Paper
BR#1616)

Existing coal-fired capacity
potentially offers the lowest variable cost power production option if these
units are upgraded to optimize capacity, operating cost (including fuel),
efficiency, and availability while also meeting today’s stringent emissions
control requirements. This paper highlights a variety of boiler system
upgrades and enhancements which are being utilized to make aging coal-fired
boilers low cost competitors in the 1990s.

Life and Availability Improvement Program” (2006 Portfolio)

Participants in the Boiler Life and
Availability Improvement Program will receive technology, forums for
information exchange, and support to safely and reliably operate boiler
components while maximizing economic return. More specifically, efforts will
be geared to reducing the impact of boiler tube failures, the highest source
of fossil plant availability loss, to less than 1%. This program contains
three projects that broadly address major boiler component nondestructive
evaluation (NDE), condition assessment, repair, replacement and cost-benefit
decision making. The program provides members with the earliest information
on emerging issues affecting boiler component reliability. Specific
guideline reports are provided and routinely updated to direct fossil power
plant life management efforts for boiler tubing, headers and drums, and
high-energy piping systems. Each of the projects depends on the other two to
provide an integrated, overall approach.

plants” (CCC/41, December 2000)

This report discusses the prospects and market opportunities
for upgrading conventional pulverised coal-fired plants. It covers the
retrofitting and upgrading of pulverisers and their fuel distribution
system, particulate control, flue gas desulphurisation, and NOx abatement
and control measures. Process optimisation to minimise pollutant formation
and improve boiler efficiency is also described. The two repowering options
covered are circulating fluidised bed boilers and the integration of a
natural gas turbine to form a combined cycle.

The Power Plant Improvement
Initiative (PPII) was established in October 2000 to further the
commercial-scale demonstration of clean coal technologies at existing and
new electric generating facilities. The goals of PPII are geared toward
demonstrating near-term advances in technologies to increase the efficiency,
lower the emissions, and improve the economics and overall performance of
coal-fired power plants, and will build on the successes gained through the
Clean Coal Technology Demonstration Program (CCTDP). Projects will focus on
more effective and lower cost emission controls, and improving the
by-product utilization, performance and reliability of power plants.
