ADVANCED MONITORING TO IMPROVE COMBUSTION TURBINE/COMBINED CYCLE CT/(CC) RELIABILITY, AVAILABILITY AND MAINTAINABILITY (RAM)
Power generators are concerned with the maintenance costs associated with the advanced turbines that they are purchasing. Since these machines do not have fully established operation and maintenance (O&M) track records, power generators face financial risk due to uncertain future maintenance costs. This risk is of particular concern, as the electricity industry transitions to a competitive business environment in which unexpected O&M costs cannot be passed through to consumers. These concerns have accelerated the need for intelligent software-based diagnostic systems that can monitor the health of a combustion turbine in real time and provide valuable information on the machine's performance to its owner/operators. EPRI, Impact Technologies, Boyce Engineering, and Progress Energy have teamed to develop a suite of intelligent software tools integrated with a diagnostic monitoring platform that will, in real time, interpret data to assess the ''total health'' of combustion turbines. The Combustion Turbine Health Management System (CTHM) will consist of a series of dynamic link library (DLL) programs residing on a diagnostic monitoring platform that accepts turbine health data from existing monitoring instrumentation. The CTHM system will be a significant improvement over currently available techniques for turbine monitoring and diagnostics. CTHM will interpret sensor and instrument outputs, correlate …

Ammonia-Free NOx Control System
Research is being conducted under United States Department of Energy (DOE) Contract DEFC26-03NT41865 to develop a new technology to achieve very low levels of NOx emissions from pulverized coal fired boiler systems by employing a novel system level integration between the PC combustion process and the catalytic NOx reduction with CO present in the combustion flue gas. The combustor design and operating conditions will be optimized to achieve atypical flue gas conditions. This approach will not only suppress NOx generation during combustion but also further reduce NOx over a downstream catalytic reactor that does not require addition of an external reductant, such as ammonia. This report describes the work performed during the January 1 to March 31, 2004 time period.

Budget Issues: Reprogramming of Federal Air Marshal Service Funds in Fiscal Year 2003
Correspondence issued by the General Accounting Office with an abstract that begins "On May 15, 2003, and again on July 25, 2003, the Department of Homeland Security (DHS) notified the House and Senate Committees on Appropriations, Subcommittees on Homeland Security, of its intention to reprogram a large amount of funds appropriated to the Transportation Security Administration (TSA) for fiscal year 2003. In an August 2003 letter, Congress requested that we review the key events leading up to the reprogramming and subsequent revisions as they related to the Federal Air Marshal Service (FAMS). In particular, we were asked to determine (1) whether senior TSA, DHS, and Office of Management and Budget (OMB) officials were informed of the implications of the FAMS funding reductions prior to submission of the reprogramming notices; (2) the programmatic implications of the funding reductions on the FAMS program; (3) whether it was legally necessary to send an impoundment message to the Congress; and whether the Secretary of Homeland Security had delegated to the Under Secretary for Management the authority to transmit reprogramming notifications to the cognizant Appropriations Subcommittees. Finally, Congress asked us to identify, as appropriate, improvements in budget execution for future consideration. As agreed, we briefed …

C1 CHEMISTRY FOR THE PRODUCTION OF ULTRA-CLEAN LIQUID TRANSPORTATION FUELS AND HYDROGEN
Faculty and students from five universities--the University of Kentucky, University of Pittsburgh, University of Utah, West Virginia University, and Auburn University--are collaborating in a research program to develop C1 chemistry processes to produce ultra-clean liquid transportation fuels and hydrogen, the zero-emissions transportation fuel of the future. The feedstocks contain one carbon atom per molecular unit. They include synthesis gas (syngas), a mixture of carbon monoxide and hydrogen produced by coal gasification or reforming of natural gas, methane, methanol, carbon dioxide, and carbon monoxide. An important objective is to develop C1 technology for the production of liquid transportation fuel and hydrogen from domestically plentiful resources such as coal, coalbed methane, and natural gas. An Industrial Advisory Board with representatives from Chevron-Texaco, Eastman Chemical, Conoco-Phillips, the Air Force Research Laboratory, the U.S. Army National Automotive Center (Tank & Automotive Command--TACOM), and Tier Associates provides guidance on the practicality of the research. The current report presents results obtained in this research program during the six months of the subject contract from October 1, 2002 through March 31, 2003. The results are presented in thirteen detailed reports on research projects headed by various faculty members at each of the five CFFS Universities. Additionally, an …

A CAVITY RING-DOWN SPECTROSCOPY MERCURY CONTINUOUS EMISSION MONITOR
The construction of the sampling system was completed during the past quarter. The sampling system has been built on a 3 feet x 4 feet x 2 inch breadboard table. The laser system, all the associated optics, and the mounts and hardware needed to couple the UV light into the fiber optic have also been condensed and placed on an identical 3 feet x 4 feet x 2 inch breadboard table. This reduces the footprint of each system for ease of operation at a field test facility. The two systems are only connected with a fiber optic, to bring the UV light to the CRD cavity, and a single coaxial cable used to apply a voltage to the diode seed laser to scan the frequency over the desired mercury transition. SRD software engineers applied a couple of software fixes to correct the problems of the diode seed laser drifting or mode hopping. Upon successful completion of the software fixes another long-term test was conducted. A nearly 3 day long, 24 hours/day, test was run to test out the new subroutines. Everything appeared to work as it should and the mercury concentrations were accurately reported for the entire test, with the …

Ceramic Coatings for Corrosion Resistant Nuclear Waste Container Evaluated in Simulated Ground Water at 90?C
Ceramic materials have been considered as corrosion resistant coatings for nuclear waste containers. Their suitability can be derived from the fully oxidized state for selected metal oxides. Several types of ceramic coatings applied to plain carbon steel substrates by thermal spray techniques have been exposed to 90 C simulated ground water for nearly 6 years. In some cases no apparent macroscopic damage such as coating spallation was observed in coatings. Thermal spray processes examined in this work included plasma spray, High Velocity Oxy Fuel (HVOF), and Detonation Gun. Some thermal spray coatings have demonstrated superior corrosion protection for the plain carbon steel substrate. In particular the HVOF and Detonation Gun thermal spray processes produced coatings with low connected porosity, which limited the growth rate of corrosion products. It was also demonstrated that these coatings resisted spallation of the coating even when an intentional flaw (which allowed for corrosion of the carbon steel substrate underneath the ceramic coating) was placed in the coating. A model for prediction of the corrosion protection provided by ceramic coatings is presented. The model includes the effect of the morphology and amount of the porosity within the thermal spray coating and provides a prediction of the …

CFD SIMULATIONS OF JOINT URBAN ATMOSPHERE DISPERSION FIELD STUDY 2003
In the Spring of 2003, a series of dispersion field experiments (Joint Urban 2003) were conducted at Oklahoma City. These experiments were complimentary to the URBAN 2000 field studies at Salt Lake City (Allwine, et. al, 2002) in that they will provide a second set of comprehensive field data for evaluation of CFD as well as for other dispersion models. In contrast to the URBAN 2000 experiments that were conducted entirely at night, these new field studies took place during both daytime and nighttime thus including the possibility of convective as well as stable atmospheric conditions. Initially several CFD modeling studies were performed to provide guidance for the experimental team in the selection of release sites and in the deployment of wind and concentration sensors. Also, while meteorological and concentration measurements were taken over the greater Oklahoma City urban area, our CFD calculations were focused on the near field of the release point. The proximity of the source to a large commercial building and to the neighboring buildings several of which have multi-stories, present a significant challenge even for CFD calculations involving grid resolutions as fine as 1 meter. A total of 10 Intensive Observations Periods (IOP's) were conducted within …

Combustion Turbine (CT) Hot Section Coating Life Management
The integrity of coatings used in hot section components of combustion turbines is crucial to the reliability of the buckets. This project was initiated in recognition of the need for predicting the life of coatings analytically, and non-destructively; correspondingly, three principal tasks were established. Task 1, with the objective of analytically developing stress, strain and temperature distributions in the bucket and thereby predicting thermal fatigue (TMF) damage for various operating conditions; Task 2 with the objective of developing eddy current techniques to measure both TMF damage and general degradation of coatings and, Task 3 with the objective of developing mechanism based algorithms. Task 4 would be aimed at verifying analytical predictions from Task 1 and the NDE predictions from Task 3 against field observations. Task 5 would develop a risk-based decision analysis model to make run/repair decisions. This report is a record of the progress to date on these four tasks.

CROSS-ROLL FLOW FORMING OF ODS ALLOY HEAT EXCHANGER TUBES FOR HOOP CREEP ENHANCEMENT
Mechanically alloyed oxide dispersion strengthened (ODS) Fe-Cr-Al alloy thin walled tubes and sheets, produced via powder processing and consolidation methodologies, are promising materials for eventual use at temperatures up to 1200 C in the power generation industry, far above the temperature capabilities of conventional alloys. Target end-uses range from gas turbine combustor liners to high aspect ratio (L/D) heat exchanger tubes. Grain boundary creep processes at service temperatures, particularly those acting in the hoop direction, are the dominant failure mechanisms for such components. The processed microstructure of ODS alloys consists of high aspect ratio grains aligned parallel to the tube axis, a result of dominant axial metal flow which aligns the dispersoid particles and other impurities in the longitudinal direction. The dispersion distribution is unaltered on a micro scale by recrystallization thermal treatments, but the high aspect ratio grain shape typically obtained limits transverse grain spacing and consequently the hoop creep response. Improving hoop creep in ODS-alloy components will require understanding and manipulating the factors that control the recrystallization behavior, and represents a critical materials design and development challenge that must be overcome in order to fully exploit the potential of ODS alloys. The objectives of this program are to …

Defense Acquisitions: Assessments of Major Weapon Programs
A letter report issued by the General Accounting Office with an abstract that begins "Although the weapons that the Department of Defense (DOD) develops have no rival in superiority, there still remain ways in which they can be improved. GAO's reviews over the past 20 years have found consistent problems with weapon acquisitions--cost increases, schedule delays, and performance shortfalls--along with underlying causes, such as pressure on managers to promise more than they can deliver. DOD can resolve these problems by using a knowledge-based approach derived from the best practices of successful product developments. GAO's goal for this report is to provide congressional and DOD decision makers with an independent, knowledge-based assessment of selected defense programs that identifies potential risks and offers an opportunity for action when a program's projected attainment of knowledge diverges from the best practice. It can also highlight those programs that employ practices worthy of emulation by other programs. GAO plans to update and issue this report annually."

Defense Acquisitions: DOD Needs to Better Support Program Managers' Implementation of Anti-Tamper Protection
A letter report issued by the General Accounting Office with an abstract that begins "The U.S. government has invested hundreds of billions of dollars in developing the most sophisticated weapon systems and technologies in the world. Yet, U.S. weapons and technologies are vulnerable to exploitation, which can weaken U.S. military advantage, shorten the expected combat life of a system, and erode the U.S. industrial base's technological competitiveness. In an effort to protect U.S. technologies from exploitation, the Department of Defense (DOD) established in 1999 a policy directing each military service to implement anti-tamper techniques, which include software and hardware protective devices. This report reviews DOD's implementation of the anti-tamper policy as required by the Senate report accompanying the National Defense Authorization Act for Fiscal Year 2004."
