FLEXIBILITY SOLUTION

AdvX® FLX

Operational Flexibility

With plants increasingly operating at lower loads and capacity factors, traditional systems – designed for high-load conditions – face new operational challenges, particularly in cycling generation profiles.

The AdvX® FLX system is engineered to remove these constraints, providing greater operational flexibility while delivering significant cost savings in both the short and long term. This low-cost, high-impact solution eliminates efficiency losses when paired with an APH upgrade, allowing power plants to operate more flexibly and efficiently.

Typical Plant Operational Constraints

  • SDA/CDS: SO2 removal, Wastewater evaporation capacity, Minimum load/temperature
  • Steam Generator: Coal moisture/mill temp, APH average cold-end temperatures, Acid dewpoint corrosion

System Benefits

  • Increases dry scrubber inlet temperature for improved performance
  • Optimizes mill temperature to enhance combustion efficiency
  • Raises APH average cold-end temperature (ACET) to minimize corrosion and fouling

The system features a high-efficiency APH element configuration, paired with an advanced X-ratio management system, adaptable to air or gas bypass duct arrangements. Custom optimization ensures seamless integration tailored to your plant’s needs.

Example Project

A utility customer was forced into operating and maintaining a costly, temporary wastewater treatment system due to low capacity factors resulting in reduced evaporation capacity in their SDA. LJUNGSTRÖM’s AdvX® FLX solution incorporated an upgrade to the air preheater that will improve wastewater evaporation and eliminate the costs of additional wastewater treatment.

  • Increase SDA inlet temperature by 20°F
  • Increase ACET by 10°F
  • Increase mill temp by 10°F
  • Improve heat rate at high loads

ZERO LIQUID DISCHARGE

AdvX® ZLD

Zero Liquid Discharge

AdvX® ZLD introduces breakthrough technology that makes Zero Liquid Discharge (ZLD) both practical and cost-effective. By recovering energy for wastewater evaporation without impacting boiler heat rate, it significantly reduces or often eliminates wastewater treatment in FGD systems, optimizing efficiency while minimizing environmental impact.

Our state-of-the-art Zero Liquid Discharge System leverages excess heat to enhance operational efficiency, cut costs, and reduce waste. By integrating advanced Ljungström® Air Preheater technology, a compact spray dryer system, interconnecting ductwork, and smart controls, it delivers a seamless, low-disruption solution for your plant.

Non-Disruptive

Recover energy for wastewater evaporation without impacting boiler heat rate.

  • No impact on boiler heat rate
  • Significant energy recovery
  • Ideal for wastewater treatment systems

Cost-Effective Wastewater Evaporation

Use existing heat sources to optimize efficiency and cost.

  • Reduce or even eliminate FGD wastewater treatment costs
  • Cost-effective evaporation solutions
  • Reduces chloride levels in FGD systems

Fast ROI + Operational Improvements

Experience rapid payback and substantial long-term savings with waste energy reinvestment.

  • Payback periods as short as 1–3 years
  • Boosts boiler efficiency
  • Reduces environmental impact

STACK GAS REHEAT

AdvX® SGR

Stack Gas Reheat

The AdvX® Stack Gas Reheat system captures and utilizes excess heat from flue gas, significantly improving operational efficiency while delivering substantial cost savings. Designed for minimal installation and maintenance, this system provides a high-impact solution with little hassle.

Leveraging LJUNGSTRÖM’s advanced air preheater technology, the system efficiently recovers excess heat from flue gas and repurposes it for stack gas reheat after a wet flue gas desulfurization (WFGD) system. Additionally, it can be tailored to enhance boiler efficiency by supplying hotter air for combustion, improving heat rate, and reducing fuel consumption. By lowering flue gas temperature, the system also significantly reduces particulate emissions and increases mercury capture for improved environmental compliance.

High-efficiency APH element configuration for enhanced heat recovery

X-ratio management system with optimized airflows matched to plant operations

Dedicated AdvX® air duct routed to the stack for efficient heat transfer.

Proprietary gas mixer for uniform distribution and improved reheat efficiency.

Optional fuel-specific SO3 mitigation system, ensuring seamless integration with existing infrastructure.

By streamlining operations, reducing costs, and improving emissions control, AdvX® Stack Gas Reheat is the smart choice for power plants seeking maximum efficiency with minimal disruption.
