0118: Operation and Maintenance Issues with Advanced Combustion Turbines

This report explains the growth of advanced technology combustion turbines (CTs) installed and operated in North America. It tracks the growth of the industry since 1985 and the changes that have occurred. While the report concentrates on operation and maintenance issues (O&M) associated with these CTs, other issues, such as the impact of high natural gas prices on the O&M costs, are discussed. It is noted that these advanced turbines can generate power at efficiencies approaching 60% (LHV Basis

0114: Boiler Tube and Pressure Parts Inspection and Assessment

This report surveys the current state of the art of inspection and life assessment tools and techniques for boiler tubing, headers, pressure piping and other high temperature pressure components. The 87 technologies identified generally have become available or have been under development since 1998 or more recently.The report classifies technologies as commercial or emerging and further sub-classifies them based on their component Nondestructive Evaluation (NDE), component life assessment, on-

0142: On-Line Monitoring and Evaluation of Critical Components

The main objective of this project is to identify the current state of the art for on-line monitoring equipment currently available as well as emerging technologies that may be applicable to critical power plant equipment. This project involved member and non-member utilities as well as industry specialists to document these technologies in a format to capture the advantages and disadvantages of each, the capabilities, the industry acceptance, and industry experience. Several case studies releva

0152: Identification and Mitigation of Barriers to Reducing Minimum Loads and Improving Ramp Rates for Coal-Fired Power Plants and Natural Gas Fired Combined Cycle Gas Turbines (CCGT)

This study provides information on plant improvements to increase ramp rates and decrease minimum stable operating loads. CEATI TGIG members were interviewed with a detailed analysis and past experiences to identify those areas of coal-fired power plants and natural gas-fired CCGTs that can be barriers to and limit a power plant, reducing minimum load capabilities and increasing ramp rates. Consequences associated with operating power plants at minimum loads are identified, and each barrier to m

0137: Preservation Guidelines for CCGT & Conventional Power Plant during Short & Long Term Shutdowns

This study covers the preservation techniques used for CCGT and CPP units that will be shutdown for short or extended periods, i.e. both the wet and dry storage methods. Information onlay-up practices and preservation techniques has been brought together from published andunpublished sources and critically analysed by ETD preservation experts and in addition asurvey of plant operator experience was carried out to examine the preservation procedures thathave been/ are being used by some of the pa

0154: thermalAMP Consolidated Thermal Generation Equipment Condition Assessment Guide - Version 1.0

In 2019 the members of the CEATI Thermal Generation Interest Group (TGIG) identified a gap in thermal plant condition assessment, scoring and documentation. The suggestion was made and supported to develop condition assessment guides following the work previously completed by hydroAMP (CEATI Report No. T172700-0367-2, hydroAMP Guide, Hydropower Asset Condition Assessment, Rev 2.0, April 2018). This initiative has led to a collaborative effort by the TGIG members to develop thermalAMP, a series o

0117: Investigation on State of the Art "Expert" Systems for Maintenance of Thermal Power Plant Equipment

A survey was conducted of the existing maintenance expert systems that are currently available to industry. This survey included evaluating existing suppliers of these technologies and determining their applicability to the power plant environment. After refining review criteria, eight supplier products were chosen for detailed analysis, which included review of supplier literature, visiting installations of some products, and meeting with suppliers to witnessdemonstrations of other products.

0145: Technology and Economic Evaluation Methodology for Fast and Flexible Generation

The installed capacity of renewable energy resources - primarily wind and solar photovoltaics (PV) - has been rising steadily in North America over the past 10 years. As wind and solar PV account for a large share of the generation mix, their intermittency and non-dispatchable nature pose challenges for grid operators and electric utilities. Output from these renewable resources can drop - or rise - suddenly, affecting electric power operations by making the balancing of load and generation more
