Show gaseous effluent from the cyclonic combustor can be cleaned using available technologies (fabric filters, scrubbers, etc.) IGT's Advanced Multipurpose Incinerator is a novel approach to staged incineration/combustion technology[5] with the following unique features: • The ability to process solid, liquid, and gaseous wastes in a single system • A patented sloped grid that enhances solids-circulation patterns within the fluidized bed, promotes complete gassolids mixing and even temperature distribution for higher contaminant ORE • An ash-discharge port with no moving parts, which provides precise discharge rate control and size classification proven in over 10,000 hours of service in a 3-foot-diameter, 24-ton/day coal gasification unit • A central air/fuel jet, which permits efficient combus-tion of natural gas or other fuels within the fluidized bed, while producing a hot zone of controlled size and temperature for the production of agglomerates • A central hot zone, which agglomerates and encapsulates the solids while the cooler surrounding bed scrubs the more volatile inorganics for ultimate removal with the agglomerates • The recycling of elutriated fines to minimize particulate and volatile metals emissions • Staged processing, which insures high organic component ORE and low CO, THC, SOx' and NOx in spite of changing feed conditions • High heat-transfer rates and low air/fuel ratios that allow high treatment capacities in relatively compact, transportable equipment. Thus, for the example of soil contaminated with organics and inorganics, the multipurpose incinerator captures and immobilizes inorganics and heavy metal contaminants in soil in the first stage, while operating in a continuous-feeding mode, by vitrifying the inorganic soil matrix. Some destruction of organic contaminants will also take place in the first stage; however, high organic ORE is expected to be accomplished in the second-stage cyclonic incinerator. The Advanced Multipurpose Incinerator should be most effectively applied at sites -- • Where a removal and treatment approach is required • Which contain combined organic and inorganic or heavy metals contamination, with or without the presence of radionuclides -7- INSTITUTE o F GAS TEe H N 0 LOG Y |
