With applicability to most types of boilers, including heat-recovery steam generators, this course is practically oriented but grounded on solid theoretical foundations of Boiler Cycle Chemistry & Industrial Water Chemistry & includes a half-day workshop
- Course Outline
After participating in this seminar you will be able to:Description
• Apply your knowledge of the different boiler chemical treatment technologies to determine whether you are employing best practices in your boiler system and protecting critical assets.
• Justify the importance of well designed and operated pre-treatment systems upstream of your boiler plant to increase overall plant reliability and lower operating costs.
• Interpret industry-wide guidelines and monitor key performance indicators in pre-boiler, boiler and post-boiler systems.
• Determine boiler cycles of concentration and improve chemical management
• Recognize ways to troubleshoot boiler feedwater, boiler and steam purity problems
• Identify invaluable insights on how to design for success in new boiler plant projects
There is hardly an industry that does not make use of boilers to generate steam, and boilers are generally viewed as critical to the overall success of the operation. The end use of steam varies from being the driving force in power generation to a multitude of applications and processes as heating medium or reactant. For boilers to operate efficiently, they require both a high quality feed water and the maintenance of proper water chemistry in the boiler. The steam itself needs to meet certain purity guidelines appropriate for the end use.
Water chemistry and chemical treatment play a critical role in achieving all of the above objectives. A good understanding of both is essential to troubleshoot operational problems, optimise boiler plant operations, and evaluate competitive bids of chemical water treatment. There are also regulatory, health & safety and environmental factors that play a role in the selection of the best chemical treatment for the boiler.
With applicability to most types of boilers, including heat-recovery steam generators, this course is practically oriented but grounded on solid theoretical foundations of Boiler Cycle Chemistry and Industrial Water Chemistry, and includes a half-day workshop where participants have the opportunity to work through real-plant situations.Who Should Attend
