Air
Pollution Control and Combustion Systems
Franklin Engineering integrates gas-cleaning systems for particulate,
metals, organics, acid gas, and NOx emissions control. Many of our projects
involve difficult applications such as submicron particulate, volatile
metals like mercury, or highly toxic organics such as dioxins/furans.
Our projects frequently begin with evaluation and troubleshooting of existing
air pollution collection and control systems. We determine the need, feasibility
and cost of system upgrades/retrofits to meet new regulatory standards
or increase capacity. Our services range from preliminary engineering
to detailed design, construction, and start-up. We also develop and execute
emissions test plans and specify CEMS to meet regulatory requirements.
Franklin Engineering designs waste and conventional fuel combustion systems. We retrofit existing systems to improve throughput, on-stream time, and pollutant removal efficiencies. Many of our projects involve evaluation of system compliance with regulatory standards and development of innovative operating or equipment modifications to meet the required standards.
Air Pollution Control Systems:
- Wet inertial impaction scrubbers for particulate and metals removal, including flux force/condensation enhanced designs.
- Wet and dry electrostatic collectors for particulate and metals.
- Fabric filter collectors for particulate and metals.
- High-efficiency filters for submicron particulate and mist.
- Wet absorbers for acid gas removal - HCl/Cl2, SOx, other halogen acids.
- Dry lime, lime slurry, and sodium carbonate slurry injection upstream of fabric filters for acid gas removal.
- Adsorbent based systems for dioxin/furan and mercury removal.
- Activated carbon/solvent recovery systems for VOC removal.
Combustion and Ancillary Systems:
- Rotary kiln, fluid bed, and fixed/rotary hearth incinerators for solid, liquid, and gaseous wastes.
- Various thermal oxidizer designs for gaseous and liquid wastes.
- Conventional coal-stoker, oil, and gas-fired boilers.
- Liquid waste tank farm storage and blending operations.
- Containerized and bulk solid waste staging, shredding, and feeding operations, including ram and auger feed systems.
- Sludge and direct burn feed systems for reactive/viscous wastes.
- Wet and dry ash handling systems.
- Scrubber water
handling systems involving sodium or calcium-based neutralization of
acid gases.
