Cedar Bay Cogeneration Project: A plant in transition
1994Co-Authors: Perry, R.p. LenertzAbstract:The Cedar Bay Cogeneration Project was initially developed by Applied Energy Services and contracted on a turnkey basis to Multipower Associates as part of a multiple projects agreement. Multipower Associates is a joint venture including The Pritchard Company (a wholly owned subsidiary of Black and Veatch), Marubeni Corporation, and Ahlstrom Pyropower. The project changed ownership to the Cedar Bay Generating Company at the midpoint of the construction phase. The Cedar Bay Cogeneration Plant provides 250 MW net to Florida Power and Light Company while producing up to 380,000 lb/h process steam to the adjacent Seminole Kraft Papermill. Three Ahlstrom Pyropower circulating fluidized bed boilers provide steam to a Toshiba turbine. Each boiler incorporates reheat capabilities to improve cycle thermodynamic efficiency. One reverse gas Fabric Filter is provided for each boiler to control particulate emissions. Ammonia injection (Thermal DeNo{sub x}-SNCR) is employed to limit the NO{sub x} emissions. The plant relies on a dilute phase pneumatic ash handling system to move the byproduct to an ash pelletizing complex. The original project developers required a state-of-the-art ash pelletizing system. Appreciable research has been done in adapting this new technology for this project. The ash pelletizing system transforms the ash into pellets, allowingmore » the ash to be loaded into open railcars and transported back to the coal mine by conventional material handling equipment.« less

Investigation and Demonstration of Dry Carbon-Based Sorbent Injection for Mercury Control
1997Co-Authors: Jason Ruhl, Justin Smith, Sharon Sjostrom, Sheila Haythorthwaite, Terry HuntAbstract:The U.S. Department of Energy (DOE) issued Public Service Company of Colorado (PSCO) a cost sharing contract to evaluate carbon-based sorbents for mercury control on a 600 acfm laboratory-scale particulate control module (PCM). The PCM can be configured as simulate an electrostatic precipitator, a pulse-jet Fabric Filter, or a Reverse-Gas Fabric Filter and is installed on an operating coal-fired power plant. Three different dry carbon-based sorbents were tested this quarter to determine their mercury removal capability in the different configurations. The project is currently in the seventh quarter of an eight-quarter Phase I project. Testing in all configurations is nearly complete. Original plans included the use of an on-line mercury analyzer to collect test data. However, due to very low baseline mercury concentration, on-line measurement did not provide accurate data. The project used a modified MESA method grab sample technique to determine inlet and outlet mercury concentrations. A major concern during sorbent evaluations was the natural ability of the flyash at the test site to remove mercury. This often made determination of sorbent only mercury removal difficult. The PCM was configured as a Reverse-Gas baghouse and brought online with "clean" flue gas on March 10* at an A/C of 2.0 ft/min. The dustcake forms the Filtering media in a reverse gas baghouse. In the absence of flyash, the bags were precoated with a commercially available alumina silicate material to form an inert dustcake. Some baseline tests were completed with clean gas for comparison to clean gas pulse jet tests. The PCM was reconfigured as a TOXECON unit in April 1997 with testing completed in May 1997. TOXECON, an EPIU patented technology, is a pulse-jet baghouse operating at a high A/C ratio downstream of a primary particulate colIector with sorbent injection upstream of the baghouse for air toxics removal. Mercury removals of O to 97o/0 were obtained depending on test conditions
