G562: Steam Turbine-Generator Maintenance Scheduling

The major objectives of this study were: review the practice and methodology used in the thermal generating industry for scheduling steam turbine-generator inspection outages, and recommend topics for future research and a course of action for the CEA which will lead to obtaining the maximum economic advantage from improvements to maintenance scheduling. Questionnaires were designed and sent to utilities, consulting companies, manufacturers and insurance companies around the world. Responses fro

G1015: Identifying and Quantifying Contaminants from Coal Combustion by Thermodynamic Calculations

The objective of this project was to predict the type and amount of priority species during pulverized coal (PC) and circulating fluidized bed combustion (CFBC) of coal. For the latter, the prediction was made in the presence and the absence of limestone. For this purpose, the Facility for Analysis of Chemical Thermodynamics (F.A.C.T.) method was used. Focus was on species containing sulphur, nitrogen, chlorine, arsenic, mercury, lead, cadmium and alkalis. Three low-rank coals and four bituminou

GT221: Equipment Reliability Information System User Guide

This manual describes the Equipment Reliability Information System (ERIS) operated by the Canadian Electrical Association (CEA) to maintain inventory and performance information on generation and transmission equipment. The manual is directed towards people interested in obtaining information from the system. The manual contains a general description of the system including an index of currently available reports with a description of each. In addition, the manual contains sufficient information

G105: Conversion of Existing Unit to Fluidized-Bed Combustion

This project would provide the industry with a cost and operating experience for retrofiting and existing boiler to fluidized bed combustion, experience with an industrial unit on a utility grid system as well as an opportunity to study, test and evaliate many aspects of this type of operation.

G408C: Boiler Tube Erosion Evaluation Phase II

The objective of this project was to carry out measurements of actual boiler erosion variables with different fuels and operating units, such that experimentally derived relationships could be verified as correct.Correlations derived in the ABB-CE Erosion Test Facility under simulated velocities and ash loadings were assessed by actual measurements in the NSPC - Lingan #1 and APL - Sheerness #1 boilers over a 1-3 year period.

G728: Environmental Noise Emissions From Thermal Generating Plant: A Survey of Sources, Legislation and Control Methods

The aim of this project was to identify, by means of a survey of the utility industry and of relevant Provincial legislation, the thermal generating plant whose impact upon environmental noise levels would benefit from noise attenuation. Based upon that data, the further research necessary to hasten the provision of improved noise attenuation on those plant items was identified.

G450: Identification & Control of Scaling in Recirculating Ash Disposal Systems

The scaling problems encountered in the re-circulating ash disposal systems for three Canadian Thermal Generating Stations are studied in terms of the nature and types of scale that have deposited. These stations, the Nanticoke, Poplar River and Keephills Generating Stations are unique in Canada, in that they burn significant quantities of low sulfur or lignite coal, and either currently employ, or have had previous experience in the use of a wet re-circulating system for transport of fly ash an

G146: Improving Thermal Fatigue Resistance of Welds

Under cyclic or "two-shift" operation, the superheater outlet headers of large power boilers may be susceptible to thermal-fatigue, particularly in the region of welded joints. An investigation was carried out into the effects of weld geometry and microstructure on the performance of welds in 1-1/4 Cr-1 Mo ferritic steel.Thermal-mechanical low-cycle fatigue tests were performed on tubular specimens incorporating an autogenous weld within the gauge length. The welds were produced using an automat

G891: Activation/Reuse of Fluidized Bed Waste

The focus of this project was on improving limestone utilization in circulating fluidized bed combustors (CFBC's) through the reactivation and recycle of partially utilized sorbent present in the ash.The first phase of the project involved a literature review, the outcome of which was a summary of possible methods of sorbent reactivation. The second phase involved a bench-scale study directed at investigating those methods of sorbent reactivation showing promise of being commercially viable.The
