Co-firing of Biomass in the US: Strategy and Opportunities
PD Hours: 2 Viewing Format(s): PDF Fee: $59.00 Purchase / Take Exam

3

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:
  1. Understand the main drivers behind considering a biomass co-firing strategy.
  2. Understand the limitations, constraints and oppportunities for co-firing in Progress Energy Carolinas Inc.'s coal-fired power plant fleet.
  3. Be introduced to a scorecard method of considering alternative biomass co-firing strategies.
  4. Become aware of the importance of capital investment constraints as well as the cost of coal and biomass for a particular power plant site.

Firing Opportunity Fuels With Minimized Emissions In CFB Technology
PD Hours: 2 Viewing Format(s): PDF Fee: $59.00 Purchase / Take Exam

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:
  1. 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.
  2. Learn about one of the cirtical components in most CFB's, the cyclone separator.
  3. Gain knowledge of air emission control processes offered by CFB.
  4. Study actual case histories of CFB operation, and see some of the "lessons learned" from these plants.
