State-level renewable energy portfolio standards mean that biomass fuels have become a major topic for the power generation sector. For utilities seeking to leverage biomass within their existing coal-fired power plants, they are developing strategies for both near-term and future biomass-fired power. This course explores the current status, constraints and opportunities for co-firing activities as experienced in one coal-fired power plant fleet. This course outlines the initial analysis of regional biomass supplies, assesses power plants for conversion to co-firing units, and weighs the viability of various technical methods from regional study data conducted by the KEMA group involving 19 plants.
Educational Objectives:
- Understand the main drivers behind considering a biomass co-firing strategy.
- Understand the limitations, constraints and oppportunities for co-firing in Progress Energy Carolinas Inc.'s coal-fired power plant fleet.
- Be introduced to a scorecard method of considering alternative biomass co-firing strategies.
- Become aware of the importance of capital investment constraints as well as the cost of coal and biomass for a particular power plant site.

Circulating fluidized-bed (CFB) boilers, as the name implies, burn fuel within a fluid bed in the furnace. This design allows combustion of a wide variety of fuels, which is a definite advantage at locations where alternative fuels are available for supplemental combustion with coal. This course examines a number of the alternative fuels that can supplement CFB coal combustion, and offers ideas for flexible CFB fuel selection at potentially many sites around the country.
Educational Objectives:
- Understand the variety of fuels that can be burned in a circulating fluidized-bed boiler. Fuel flexibility often offers potential cost savings regarding fuel purchases.
- Learn about one of the cirtical components in most CFB's, the cyclone separator.
- Gain knowledge of air emission control processes offered by CFB.
- Study actual case histories of CFB operation, and see some of the "lessons learned" from these plants.

The plant outlined in this course burns PRB coal, and PRB coal produces elemental mercury which can be difficult to remove. Also of significant importance at this plant and at others that sell fly ash to concrete manufacturers is that the injection of activated carbon may degrade ash properties to the point where the ash can no longer be used for concrete making. This course outlines activated carbon injection testing for mercury control at Boardman Station.
Educational Objectives:
- Learn about activated carbon injection tetsing for mercury control.
- Understand the effects of activated carbon on the resistivity of fly ash.
- Learn what improvements would allow faster absorption of mercury by powdered activated carbon.
- Understand what causes higher mercury concentration in fly ash.

A technique for reducing CO2 emissions, improving plant efficiency and potentially increasing plant capacity is to repower old coal-fired steam generators with modern combined-cycle units. This course examines one such project at a plant in Minnesota, where the project included new plant design, steam turbine upgrades, modifications to the circulating water system, plant control upgrades and others.
Educational Objectives:
- Learn about the increasingly popular technique of repowering existing steam turbines with combined-cycle systems.
- Understand the effect that switching from coal to natural gas has on air pollutant emissions.
- Understand the effects such a change has on boiler control systems.
- Learn about a number of major auxiliary system modifications that go into a repowering project.
