This course describes how superheaters, reheaters, and the economizer affect boiler efficiency and heat rate. After completing this course, participants should be able to describe how superheaters and reheaters add heat to steam, and how the economizer adds heat to feedwater. They should also be able to explain how attemperators control steam temperatures and protect superheaters and reheaters; and how problems with superheaters, reheaters, and economizers affect heat rate.
Vector Solutions has a long history of providing industry-specific content for its customers. While this course and its content remain accurate and functional within our systems, the look and feel may not match our more modern offerings.
At the end of this course, you will be able to:
Explain why superheaters are used to increase the temperature of steam.
Explain why a primary superheater and a secondary superheater are normally connected in series to superheat steam.
Explain how a reheater affects boiler efficiency and heat rate.
Explain how attemperators limit steam temperature and describe the impact that attemperators have on heat rate.
Explain how the economizer affects boiler efficiency and heat rate.
Describe the effects of ash buildup on superheaters, reheaters, and economizers and how ash buildup can be minimized.
Describe the effects of too much excess air on heat transfer in superheaters, reheaters, and economizers and why excess air should be maintained at desired levels.
