Show ADVANCED MULTIPURPOSE INCINERATOR Arnir Rehmat and Mark Khinkis Institute of Gas Technology Chicago, Illinois 60616 ABSTRACT The Institute of Gas Technology (IGT) is developing an advanced multipurpose incinerator that combines the fluidizedbed agglomeration/incineration and cyclonic combustion/ incineration technologies that have been developed separately at IGT over many years. This two-stage combination results in a unique and extremely flexible multipurpose incinerator for solid, sludge, liquid, and gaseous wastes. This system can operate over a wide range of conditions in the first stage, from low temperature (desorption) to high temperature (agglomeration), including gasification of high-Btu wastes. In the combined system, solid, liquid, and gaseous organic wastes would be easily and efficiently destroyed [>99.99% destruction and removal efficiency (DRE)], whereas solid inorganic contaminants or solid residue would be contained within a glassy matrix, rendering them benign and suitable for disposal in an ordinary landfill. This technology is different from other existing technologies because of its agglomeration and encapsulation capability and its flexibility with respect to the types of wastes it can handle. Both the fluidized bed as well as the cyclonic incineration technologies have been fully developed and tested separately at pilot scales. INTRODUCTION There is an ever increasing need for the treatment and safe disposal of a wide variety of organic and inorganic wastes. Most notably, the cleanup of sites under Superfund, the U.S. Department of Defense, and the U.S. Department of Energy has triggered an enormous interest in this area. There are now hundreds of sites on the EPA National Priority List. The types of wastes encountered include one or more of the following: • Soils contaminated with organic and inorganic (metal) contaminants • Contaminated debris, including drum carcasses, wood, rocks, concrete, scrap metal, and brush • Sludges and tars, some of which are extremely viscous and non-pumpable • Pumpable organic and aqueous slurries • Aqueous liquids -1- INSTITUTE o F GAS TEe H N 0 LOG Y |
