Air Pollution Control Equipment
Alden’s CFD and Air & Gas Flow Modeling Groups work together to address a wide variety of problems related to the performance of air pollution control equipment. Selective areas of collaboration include:
Selective Catalytic Reduction (SCR) Systems
- Flow conditioning downstream of turbine
- Velocity uniformity upstream of catalyst face
Stack Modeling
- Stack flow distribution
- Plume constituent downwash modeling
- Plume temperature profiles
Electrostatic Precipitators (ESPs)
- Flow guidance device optimization
- Particulate trajectory simulation
- Pressure drop calculation
- Box inlet and outlet velocity/temperature distribution
Baghouses
- Flow distribution between compartments
- Velocity distribution at bottom of bags
- Flow uniformity through bag surface area
- Particulate distribution between compartments/at bottom of bags
- Pressure drop calculation
Complex Duct Systems
- Flow distribution and pressure drop
- Flow guidance device devlopment and refimenment
Flue Gas Desulfurization (FGD) Systems
- Velocity distribution at sprays and mist eliminator
- Spray coverage prediction and wall fraction estimation
- Wet/dry interface identification/optomization
Other Components
- Air heaters, heat exchangers, condensers
- Fans and blowers
- Boiler windboxes
