INNOVATIVE, COST-EFFECTIVE, AND LOW PARTICULATE EMISSION INCINERATOR FOR SOLID AND LIQUID HAZARDOUS WASTES

INCREASED PUBLIC OPPOSITION TO PROPOSED PERMITS FOR LAND-BASED INCINERATOR FACILITIES AND THE GROWING MARKET TREND FOR THERMAL DESTRUCTION OF HAZARDOUS WASTES HAVE RESULTED IN A NEED FOR INNOVATIVE, COST-EFFECTIVE, AND RELIABLE TRANSPORTABLE INCINERATOR FACILITIES. THIS PROJECT PROPOSES TO ADAPT A PULSED ATMOSPHERIC FLUID-BED COMBUSTION SYSTEM FOR THERMAL DESTRUCTION OF SOLID AND LIQUID HAZARDOUS WASTES. THE OBJECTIVES ARE TO PROVIDE A COST-EFFECTIVE COMPACT, AND RELIABLE TRANSPORTABLE DESIGN THAT CAN MEET FEDERAL AND LOCAL INCINERATION REQUIREMENTS AND GUIDELINES. THE PROPOSED SYSTEM INTEGRATES THE HIGH EFFICIENCY FLUID-BED COMBUSTOR WITH A HIGH-INTENSITY OSCILLATING FLOW PULSE COMBUSTOR FOR A COMPACT AND LOW PARTICULATE AND TOXIC GAS EMISSION UNIT. THE BASIC DESIGN AND OPERATING CHARACTERISTICS OF A COAL-FIRED PULSED ATMOSPHERIC FLUID-BED COMBUSTOR HAS ALREADY BEEN DEMONSTRATED BY MTCI AT THE 1.5 MMBTU/HR SIZE FOR THE U.S. DEPARTMENT OF ENERGY. DESPITE ITS COMPACT SIZE, THE RELATIVELY HIGH VOLUMETRIC RELEASE RATE OF THE UNIT WITH ITS LOW HEIGHT (10 FT.), FAST START-UP AND FUEL INSENSITIVITY MAKE IT EMINENTLY SUITABLE FOR ON-SITE OPERATION. THE UNIT PERFORMANCE WITH RESPECT TO COMBUSTION, ENVIRONMENTAL INTRUSION, AND STEAM RATE WAS SUPERIOR TO STANDARD BUBBLING FLUID-BED AND CIRCULATING FLUID-BED COMBUSTORS. THE INTENT OF THE PHASE I PROJECT IS TO CONDUCT A SET OF TRIAL BURNS WITH A SURROGATE WASTE ON THE EXISTING PAFBC FACILITY TO DEMONSTRATE ITS FEASIBILITY FOR DESTRUCTION OF HAZARDOUS WASTES.
