Consensus on pre-commissioning stages for cogeneration and combined cycle power plants : an ASME research report

This publication is an important adjunct to several previously published documents prepared to inform, educate and assist the reader in adequately considering and planning for the many major activities involved in the design, construction and start-up of cogeneration and combined cycle power plants. Experience has shown that failure to consider the complex interrelationships between the various component systems can result in costly delays in project completion and turn over dates. Additionally, incorrect procedures and planning can result in damage or failure of key pieces of equipment or systems during subsequent operation. This consensus was prepared by a task group of this subcommittee under the leadership of Edward Beardwood. The task group consisted of representatives of manufacturers, operators and consultants involved with the planning, design, manufacture, operation and monitoring of industrial and utility boilers, steam generators and associated equipment and systems. The ASME Research and Technology Committee on Water and Steam in Thermal Systems will review, revise and reissue this document from time to time as necessary to comply with advances in technology in the design of these plants and the water treatment options.
