An Investigation of Air Emission Reduction Methods for Aircraft Rescue and Firefighter Training Fires: Small-Scale Tests
Final rept. for 1996-1997

Pagination or Media Count:
Small-scale experiments were conducted to examine pollutant reduction techniques for JP-5 spray fires. These tests were part of a program to relocate the fire training facility at Naval Air Training Center NATTC Millington to NATTC Pensacola. The use of water spray, fuel additives, and water emulsion was investigated. Water spray was identified as the most feasible technique for immediate use at the facility. The water spray system was optimized by examining nozzle spray characteristics, nozzle configurations, and water-to-fuel ratios. A smoke reduction of 96 percent was achieved for a water-to-fuel ration of 9.1. Emissions factors for carbon monoxide, sulfur dioxide, nitric oxides, and total hydrocarbons were developed. These factors provide a better estimation of fire trainer emissions than those currently available.
