  • managing slagging at Monroe Power Plant using on line coal analysis and fuel blending
    Fuel Processing Technology, 2007
    Co-Authors: David A Tillman, Dao Duong
    Abstract:

    Monroe Power Plant of DTE Energy is a 3100 MW (net) station in southeastern Michigan. This station consists of four Babcock & Wilcox wall-fired boilers firing blends of southern Powder River Basin (PRB) subbituminous coal along with Central Appalachian bituminous coals. The station manages the coal properties in the various fuel blends using an on-line analyzer. This analyzer measures the complete proximate analysis, the heating value, and the ash chemistry of the coal being loaded into the silos. The on-line analyzer program has been used to control the slagging properties of the coal being burned, with the result being a dramatic reduction in costly slagging incidents at the Plant. The on-line analyzer is used to guide modifications to the blend; it is also used to provide guidance to operators concerning the fuel being fed to pulverizers and burners. This paper describes this effort in the context of an overall combustion program and it details the results of that program.

  • Evaluation of Sorbent Injection for Mercury Control: Final Report
    'Office of Scientific and Technical Information (OSTI)', 2008
    Co-Authors: Sjostrom Sharon
    Abstract:

    ADA-ES, Inc., with support from DOE/NETL, EPRI, and industry partners, studied mercury control options at six coal-fired Power Plants. The overall objective of the this test program was to evaluate the capabilities of activated carbon injection at six Plants: Sunflower Electric's Holcomb Station Unit 1, AmerenUE's Meramec Station Unit 2, Missouri Basin Power Project's Laramie River Station Unit 3, Detroit Edison's Monroe Power Plant Unit 4, American Electric Power's Conesville Station Unit 6, and Labadie Power Plant Unit 2. These Plants have configurations that together represent 78% of the existing coal-fired generation Plants. The financial goals for the program established by DOE/NETL were to reduce the uncontrolled mercury emissions by 50 to 70% at a cost 25 to 50% lower than the target established by DOE of $60,000 per pound of mercury removed. Results from testing at Holcomb, Laramie, Meramec, Labadie, and Monroe indicate the DOE goal was successfully achieved. However, further improvements for Plants with conditions similar to Conesville are recommended that would improve both mercury removal performance and economics

  • Evaluation of Sorbent Injection for Mercury Control
    'Office of Scientific and Technical Information (OSTI)', 2006
    Co-Authors: Sjostrom Sharon
    Abstract:

    The Power industry in the U.S. is faced with meeting new regulations to reduce the emissions of mercury compounds from coal-fired Plants. These regulations are directed at the existing fleet of nearly 1,100 boilers. These Plants are relatively old with an average age of over 40 years. Although most of these units are capable of operating for many additional years, there is a desire to minimize large capital expenditures because of the reduced (and unknown) remaining life of the Plant to amortize the project. Injecting a sorbent such as powdered activated carbon into the flue gas represents one of the simplest and most mature approaches to controlling mercury emissions from coal-fired boilers. This is the final site report for tests conducted at DTE Energy's Monroe Power Plant, one of five sites evaluated in this DOE/NETL program. The overall objective of the test program was to evaluate the capabilities of activated carbon injection at five Plants: Sunflower Electric's Holcomb Station Unit 1, AmerenUE's Meramec Station Unit 2, Missouri Basin Power Project's Laramie River Station Unit 3, Detroit Edison's Monroe Power Plant Unit 4, and AEP's Conesville Station Unit 6. These Plants have configurations that together represent 78% of the existing coal-fired generation Plants. The goals for the program established by DOE/NETL were to reduce the uncontrolled mercury emissions by 50 to 70% at a cost 25 to 50% lower than the target established by DOE of $60,000/lb mercury removed. The results from Monroe indicate that using DARCO{reg_sign} Hg would result in higher mercury removal (80%) at a sorbent cost of $18,000/lb mercury, or 70% lower than the benchmark. These results demonstrate that the goals established by DOE/NETL were exceeded during this test program. The increase in mercury removal over baseline conditions is defined for this program as a comparison in the outlet emissions measured using the Ontario Hydro method during the baseline and long-term test periods. The change in outlet emissions from baseline to long-term testing was 81%

  • Evaluation of Sorbent Injection for Mercury Control

    Abstract:

    The Power industry in the U.S. is faced with meeting new regulations to reduce the emissions of mercury compounds from coal-fired Plants. These regulations are directed at the existing fleet of nearly 1,100 boilers. These Plants are relatively old with an average age of over 40 years. Although most of these units are capable of operating for many additional years, there is a desire to minimize large capital expenditures because of the reduced (and unknown) remaining life of the Plant to amortize the project. Injecting a sorbent such as powdered activated carbon into the flue gas represents one of the simplest and most mature approaches to controlling mercury emissions from coal-fired boilers. The overall objective of the test program described in this quarterly report is to evaluate the capabilities of activated carbon injection at five Plants with configurations that together represent 78% of the existing coal-fired generation Plants. This technology was successfully evaluated in NETL's Phase I tests at scales up to 150 MW, on Plants burning subbituminous and bituminous coals and with ESPs and fabric filters. The tests also identified issues that still need to be addressed, such as evaluating performance on other configurations, optimizing sorbent usage (costs), and gathering longer-term operating data to address concerns about the impact of activated carbon on Plant equipment and operations. The four sites identified for testing are Sunflower Electric's Holcomb Station, AmerenUE's Meramec Station, AEP's Conesville Station, and Detroit Edison's Monroe Power Plant. In addition to tests identified for the four main sites, parametric testing at Missouri Basin Power Project's Laramie River Station Unit 3 has been scheduled and made possible through additional costshare participation targeted by team members specifically for tests at Holcomb or a similar Plant. This is the fifth quarterly report for this project. Long-term testing was completed at Meramec during this reporting period. Preliminary results from parametric, baseline and long-term testing at Meramec are included in this report. Planning information for the other three sites is also included. In general, quarterly reports will be used to provide project overviews, project status, and technology transfer information. Topical reports will be prepared to present detailed technical information

  • Using On-Line Coal Analysis to Optimize Combustion in Utility Boilers: a 10-yr Program at Monroe Power Plant
    2012
    Co-Authors: Tillman, David A.
    Abstract:

    Monroe Power Plant (MPP) of DTE Energy, a 3200 MW generating station fired with blends of Powder River Basin subbituminous coal and Central Appalachian bituminous coal, has developed and advanced the technologies of on-line coal analysis. Technologies involved include both the analytical instrumentation and the communication of results to operators trained in the use of these results. At MPP the x-ray fluorescence (XRF) analyzer provides the full proximate analysis and calorific value of the fuel being transported to the silos; it also provides the complete ash elemental analysis of this fuel. Through additional statistical manipulation the XRF provides ultimate analysis data to the operator. The XRF obtains a data set every 90 seconds. The software used to transmit the data to the Power Plant operators, developed by Engineering Consultants Group (ECG) of Akron, OH, provides operators, shift supervisors, and engineering staff with data concerning the fuel being burned at the present time, fuel that can be expected in 1 hr, 2 hrs, 4 hrs, and the fuel being loaded into the silos. The information provided to operations includes an assessment of the quality of the fuel from several perspectives: calorific value, moisture content, ash loading, and ash chemistry. Further, using the analyzer and associated PI data, the operator can obtain real time boiler efficiency and flyash resistivity data. Training of personnel provides staff with insights into the meaning of the data, and appropriate responses to the data. For example, the operations group, led by the shift supervisor, periodically adjusts the blend to optimize calorific value, minimize slagging and fouling potential, manage the use of SO3 for flyash conditioning, and manage the use of REF additive for emissions control. These capabilities have been employed by the Plant for the past several years, facilitating operation of the four units at MPP. This paper describes the system, its usage, and its technical benefits to the generating station
