Tetra In Action #4 - July, 2016
Come see us at the PowerGen Asia conference in Seoul! And read about Boiler Preservation Engineering...
This seminar is primarily intended for O&M staff at all levels of experience working in combined cycle power plants, but should also be of interest to engineers and managers involved in new project development. The course gives attendees a comprehensive yet in-depth survey of a broad range of topics relating to the design, operation and maintenance of the HRSG and associated steam cycle systems. Drawing on our field experience working at power plants throughout the world, the objective is to provide attendees with clear instruction on the operator actions and design issues that impact HRSG reliability, efficiency and operating life.
TETRA Engineering was engaged by a European client to perform a site works assessment at a Southeast Asian power plant construction site. Work had been delayed for months due to disagreements among two parties involved in the project regarding scope of work, responsibility and scheduling issues.
A Tetra engineer visited the site to meet with key personnel from the parties and to inspect the current state of the works. The results of the survey revealed
Analysis of deposits found in the HRSG is a common and very useful way for determining what is occurring on both the waterside and gas side. Waterside deposits found in the drum are analyzed to determine chemical and elemental composition. The presence of certain elements such as chlorine might indicate that there is or was a problem with contamination of the boiler water. Analysis of gas side deposits such as those found on the cold end tubes can identify the various compounds present and their disposition in the deposits. Excessive cold end deposition results when unit design does not match actual fuel characteristics or from mistuned process conditions. The deposits are often corrosive and can lead to premature tube failures as well as loss HRSG or boiler performance.
