Title: McIntosh Unit 4 PCFB demonstration project

Abstract

The City of Lakeland, Foster Wheeler Corporation and Westinghouse Electric Corporation have initiated a full scale demonstration of Pressurized Circulating Fluidized Bed (PCFB) Technology at Lakeland`s McIntosh Power Station in Lakeland, Florida. Two technologies will be demonstrated sequentially in the project: (1) the non-topping version of the PCFB where the gas turbine is driven directly by hot flue gases exhausted from the boiler, and (2) the topping version of the PCFB where the hot flue gases from the boiler are fired with syngas to raise the gas turbine inlet temperature. Each of these versions of the technology has its advantages and both will serve different future markets. The total project duration will be approximately eight years and will be structured into three separate phases: two years of design and permitting, followed by an initial period of two years of fabrication and construction and concluding with a four year demonstration (commercial operation) period. It is expected that the project will show that Foster Wheeler`s PCFB technology coupled with Westinghouse`s Hot Gas filter and power generation technologies represents a cost effective, high efficiency, low emissions means of adding greenfield generation capacity and that this same technology is also well suited for repoweringmore » applications.« less

  • The City of Lakeland, Foster Wheeler Corporation and Westinghouse Electric Corporation have embarked on a utility scale demonstration of Pressurized Circulating Fluidized Bed (PCFB) technology at Lakeland`s McIntosh Power Station in Lakeland, Florida. The US Department of Energy will be providing approximately $195 million of funding for the project through two Cooperative Agreements under the auspices of the Clean Coal Technology Program. The project will involve the commercial demonstration of Foster Wheeler Pyroflow PCFB technology integrated with Westinghouse`s Hot Gas Filter (HGF) and power generation technologies. The total project duration will be approximately eight years and will be structured intomore » three separate phases; two years of design and permitting, followed by an initial period of two years of fabrication and construction and concluding with a four year demonstration (commercial operation) period. It is expected that the project will show that Foster Wheeler`s Pyroflow PCFB technology coupled with Westinghouse`s HGF and power generation technologies represents a cost effective, high efficiency, low emissions means of adding greenfield generation capacity and that this same technology is also well suited for repowering applications.« less
  • The City of Lakeland, Florida, Foster Wheeler and the Westinghouse Electric Corporation have embarked on the demonstration of a Clean Coal Technology at the City of Lakeland`s McIntosh Power Station in lakeland, Polk County, Florida. The project will demonstrate the Pressurized Circulating Fluidized Bed Combustion (PCFB) technology developed by Foster Wheeler and Westinghouse. The Lakeland McIntosh Unit 4 Project is a nominal 170 MW power plant designed to burn a range of low- to high-sulfur coals. The combined cycle plant employs a Westinghouse 251B12 gas turbine engine in conjunction with a steam turbine operating in a 2400/1000/1000 steam cycle. Themore » plant will demonstrate both the PCFB and topped PCFB combustion technologies. This paper provides a process description of the Foster Wheeler PCFB and Topped PCFB technologies and their application to the Lakeland McIntosh Unit 4 Project.« less
  • In December 1997, the City of Lakeland, Florida, signed a Cooperative Agreement with the US Department of Energy (DOE) that will facilitate the demonstration of the Advanced Circulating Fluidized-Bed Combined Cycle (ACFBCC) technology being developed by Foster Wheeler. The project will be conducted under the DOE Clean Coal Technology Program at the City of Lakeland's McIntosh Power Station in Lakeland, Florida. In August 1998, Lakeland released Foster Wheeler to begin preliminary engineering and permitting support of the demonstration plant. The Lakeland McIntosh Unit 4 Project is a nominal 240 MWe combined cycle plant that integrates the partial gasification of coalmore » with pressurized circulating fluidized bed (PCFB) combustion. The partial gasification process produces a low Btu syngas and a coal char residue. The latter is burned in a PCFB boiler producing steam for a steam turbine and hot vitiated air/flue gas for a gas turbine. The syngas, in turn, is burned in the gas turbine (topping combustion) to heat the vitiated air to over 2,300 F. The plant is designed to burn both low and high sulfur coal and incorporates a Siemens V64.3 gas turbine with a 2,400 psig/1,000 F/1,000 F steam turbine. This paper describes the demonstration plant and identifies its design status.« less
  • Midwest Power, Dairyland Power Cooperative, Pyropower Corporation (a subsidiary of Ahlstrom Pyropower Inc.), and Black & Veatch have embarked on the demonstration of Clean Coal Technology at Midwest Power`s Des Moines Energy Center (DMEC) in Pleasant Hill, Iowa. The DMEC-1 PCFB Repowering Project has been awarded $93,253,000 from the US Department of Energy for the demonstration of AHLSTROM PYROFLOW{reg_sign} First Generation Pressurized Circulating Fluidized Bed (PCFB) Technology. The project team has completed a detailed evaluation of an 80 MWe PCFB demonstration unit for repowering of the No. 6 steam turbine at the DMEC site. During the course of that analysis,more » a significant opportunity was identified to enhance the economics of the project. This has resulted in an extension of the first budget period of the project to allow alternative configurations to be evaluated in more detail. The modified plant configuration is expected to have substantially improved economics and plant efficiency. This paper will provide a technical and economic comparison of the original 80 MWe design with several alternative configurations and will discuss the resulting plans for the demonstration of Pyroflow PCFB technology on Midwest Power`s power generation system.« less
  • The market drivers for the Electric Utility Industry have significantly changed during the 1990`s. Increasing environmental regulatory requirements mandated by the Clean Air Act Amendments, coupled with pressures to become the lowest cost producer in an unregulated utility market, have altered the traditional approach that Utility Companies have taken to better position themselves for the electric utility business of the future. This paper reviews a project at Savannah Electric`s Plant McIntosh Unit {number_sign}1 that successfully achieved the dual objectives of environmental compliance while reducing production costs utilizing a cost effective ESP design, a customized discharge electrode configuration, and a dualmore » flue gas conditioning system. The paper details the attempts of plate straightening precluding the decision to rebuild the ESP and presents some detail on the selection and implementation of the design choices made to meet Savannah Electric`s objectives. The ESP`s performance is compared burning a Quality Challenged, low moisture, high resistivity ash coal with approximately 92% (AL{sub 2}O{sub 3}+SiO{sub 2}) in the ash. Also, the paper discusses the suitability of SO{sub 3} and NH{sub 3} conditioning to achieve opacity lower than 10%. The paper describes the sequence of events allowing the work to be done in a short outage time to minimize loss production.« less
