Advanced X-Ratio Management for CO2 Emission Reduction and Operational Flexibility

Improving a power plant’s heat rate directly reduces coal consumption and CO2 emissions. With the World focusing more on reducing greenhouse gas emissions, improving a power plant’s heat rate is one of many tools that can be implemented to improve efficiency, reduce coal consumption, and reduce CO2 emissions. A power plant’s Air Pre-heater (APH) is a critical piece of equipment for improving heat rate.

LJUNGSTROM has multiple solutions that can improve a power plant’s heat rate ranging from advanced element profiles and reduction in leakage and control.

LJUNGSTROM’s innovative AdvX®-HRI solution is also built to recover and utilize additional heat, maximizing efficiency, reducing CO2 emissions while providing significant long-term savings.

Additionally, US coal utilities are running at lower loads and capacity factors more often. Many air pollution control systems were not designed with low capacity factors in mind. Low load operation can impact:

1. SO2 removal
2. Wastewater (process water) evaporation capacity in SDA/CDS
3. Coal moisture in pulverizers, and
4. Minimum operating temperatures (Average cold-end temperatures (ACET), acid dewpoint, or SDA/CDS min load)

LJUNGSTROM’s AdvX®-FLX is a low cost system which can mitigate or eliminate these issues with little or no heat rate impact, affording power plants greater operational flexibility at lower capacity factors.

The presentation will cover basic principles of APH, AdvX® and recent case studies and projects.
