Evaluation of Air Emissions-Reduction Technologies for Aerospace Ground Equipment
Abstract
Reported are results of a U.S. Air Force effort to reduce air emissions from aerospace ground equipment (AGE), called the "Green Age" initiative. In Phase I, promising NOx-reduction technologies were identified for deployment on A/M32A-86("-86") generators at March AFB, California. In Phase II, Battelle was contracted to devise and use a numerical rating system by which to evaluate these technologies for merit. The Rating system had five criteria, totally 100 points: Emission Reduction (25), Cost (25), Reliability/Maintainability (20), Deployability (20), and Fidelity of Data (10). A reduction in NOx of greater than or equal 70% was the prime requirement, with no accompanying increase in the emission of carbon monoxide, particulates, or reactive hydrocarbons. Based on this numerical Rating system, the six candidate Green Age NOx-reduction technologies considered were ranked in the following order of decreasing merit: (1) Water-in-Fuel Firing (WFF), WL/FIVC, Tyndall AFB FL; (2) Selective Catalytic Reduction (SCR), Houston Industrial Silencing (HIS) TX; (3) NOx-Filter Cart (NFC), AL/EQ, Tyndall AFB FL; (4) Dual-Fuel Firing (DFF), BKM, San Diego CA; (5) Oxygen-Enriched Air (OEA), AL/FTS, Brooks AFB TX; and (6) Non-Thermal Discharge (NTD), WL/MNMW, Eglin AFB FL. WFF < 5CR, and NFC are recommended for further development and demonstration under Green AGE Phase III. DFF, OEA, and NTD have technical deficiencies, the resolution of which is doubtful, technically or within time.
