Introduction
This seminar will provide a comprehensive understanding of various types of circulating fluidized bed (CFB) boilers. All the components of CFB boilers including furnace, cyclones, economizers, superheaters, reheaters, ammonia injection systems, electrostatic precipitators, polishing dry scrubbers, fuel and sorbent feeding systems, bottom ash handling and extraction systems will be covered in detail. The design, selection considerations, operation, maintenance, diagnostic testing, troubleshooting, refurbishment, pay-back period, and economics as well as, emission limits, reliability, monitoring and control systems of CFB boilers will also be covered thoroughly. This seminar will focus on maximizing the efficiency, common problems and solutions, reliability, and longevity of CFB boilers by providing an understanding of the characteristics, selection criteria, common problems, and repair techniques, preventive and predictive maintenance. All the common problems encountered in CFB Boilers will be discussed in detail. This includes thermally induced failures, anchor system induced failures, water walls tube failures, NMEJ damages, clinker formation, refractory damages, APH tube chock-up. Solutions will be presented to each problem.
 
Several studies have confirmed that CFB boilers are the best method for power generation. This is due to their fuel flexibility, and lowest electricity cost among all types of boilers. This technology is in great demand due to various other advantages such as lower emissions as compared to other types of boilers and has a carbon footprint well below the norms laid down by the World Bank emission requirements. This seminar is a MUST for anyone who is involved in the selection, applications, or maintenance of circulating fluidized bed boilers, because it covers how this equipment operates, the latest maintenance techniques, and provides guidelines and rules that ensure successful operation of CFB boilers. This seminar will also provide up-dated information in respect to all the significant improvements that have been made to this equipment during the last two decades.

Education @ Your Desk. A Live Webinar Class means that you will attend the class via the web using your computer. There are scheduled breaks for coffee and lunch. You use a microphone, headset, or your phone and are able to interact with the instructor and other students while following notes while watching the presentation slides online just as you would in a live classroom. Notes are posted online. For an extra cost a hard copy can be requested.

The virtual classroom is becoming more and more popular, and we have a lot of experience teaching in this format. The only real difference between a live in-class and live via webinar is where you sit and what you look at. You can learn from the comfort of your own home or office. You pay less for the live webinar format than you would for the in-class format, and you do not have to travel to another city to attend the class. Please contact us at gic@gic-edu.com for Special Group & Corporate Rates for one or more participants.
