Clean Coal Demonstrations
Power Plant Improvement Initiative (PPII)
On October 11, 2000, the Power Plant Improvement
Initiative (PPII) was established under United States Public Law 106-291
for the commercial-scale demonstration of technologies to assure the
reliability of the Nation's energy supply from existing and new electric
generating facilities. PPII is geared toward demonstrations of advanced
near-term technologies to increase the efficiency, lower the emissions,
and improve the economics and overall performance of coal-fired power
plants. Most PPII projects focus on technologies enabling
coal-fired power plants to meet increasingly stringent environmental
regulations at the lowest possible cost. With many coal plants
threatened with shutdowns because of environmental concerns, more
effective and lower cost emission controls can keep generators running
while improving the quality of the nation’s air and water. Other
projects will improve by-product utilization, performance, and
reliability of power plants.

-
Achieving New Source Performance Standards (NSPS) through Integration
of Low NOx Burners with an Optimization Plan for Boiler Combustion -
Participant: Sunflower Electric Power Corporation
- A unique combination of high-tech
combustion modifications and sophisticated control system
modifications will be installed and tested at the 360 MWe
coal-fired boiler at Sunflower Electric's Holcomb Power Station in
Finney County, Kansas. This technology is expected to reduce air
emissions, yet save costs for rate payers.
-
Commercial Demonstration of the Manufactured Aggregate Processing
Technology Utilizing Spray Dryer Ash - Participant: Universal
Aggregates, LLC Universal Aggregates, LLC will design, build, and operate an aggregate
manufacturing plant that converts 115,000 tons/year of spray dryer by-products into 150,000 tons/year of lightweight masonry blocks or
lightweight concrete.
-
Demonstration of a Full-Scale Retrofit of
the Advanced Hybrid Particulate Collector (AHPC) Technology -
Participant: Otter Tail Power Co.
The Advanced Hybrid Particulate Collector (AHPC)
overcomes the problem
of excessive fine particle emissions that escape
collection in ESPs and
the reentrainment of dust in baghouses. The
goal of the project is
to demonstrate the AHPC concept in a
full-scale application.
-
Big Bend Power Station Neural Network – Sootblower Optimization - Participant: Tampa Electric Co. This Project applies a neural network intelligent sootblowing system
in conjunction with state-of-the-art controls and instruments to
optimize the operation of a utility boiler and systematically
control boiler fouling.
