The laboratory results proved that the SGFB incinerator produced reclaimed abrasives conforming to the requirements of MIL-A-22262A for fresh blasting abrasives. Results of Second-Stage Cyclonic Incinerator The second stage of the multipurpose incinerator, the cyclonic incinerator, has demonstrated the following advantages relative to commercially available incineration equipment: • Improved ORE • Dry-ash operation • Benign bottom ash • Higher combustion intensity • Lower excess air requirements • Reduced supplementary fuel demand • Wider range of operating temperatures • Higher turndown ratio • Extremely stable operation -12- 200 INSTITUTE o F GAS TEe H N 0 LOG Y |
