Show Typical operating plots are presented in Figures 2 and 3. Waste A is a mixture of sludges, grease and oil having a heating value 14117 BTU/lb. Waste B is a mixture of sand and slightly contaminated water having no heating value. Waste B flow rate is kept constant as in Fig. 2 and the Waste A flow is varied which in turn varies the clean fuel consumption. The unit will be operated at a Waste A flow rate of 1000 lbs./hr. to minimize clean fuel consumption. Fig. 3 provides the relationshiop between fuel rate and total air requirement at 25% and 50% excess air. The unit typically will be operated between 25%-50% excess air. MOBILE WASTE PROCESSOR -75 (MWP-75) A process flow schematic of the MWP-75 is presented in Figure 4. The MWP-75 was designed for incinerating liquid PCBs of high concentration at very high temperature. Transportation of liquid PCBs and other hazardous wastes is a major problem being faced by the hazardous waste industry. MWP-75 was designed to eliminate this problem. The entire unit is mounted on 4 trailers ( 8 1/2' wide x 40' long). Several novel ideas are incorporated in the design of MWP-75. To achieve very high destruction efficiencies, it is necessary to maintain very high flame temperature and residence time in the afterburner. An Adiabatic flame temperature of 4600 DEG.F was achieved by enriching air with pure oxygen (49% by wt. of 0 in the primary air). One of the problems of high temperature incineration is the production of high N0X. '•'N0X formation was controlled by staged combustion and by the use of 02enriched air. EPA requires that we maintain combustion products at 2200 DEG. F. with a minimum of 2 seconds residence time. Since the incineration is carried out at high temperatures, there is a need to remove heat in the primary combustor itself, and therefore it is water cooled. Fuel/air mixing vanes are designed such that the atomized fuel and the primary air travel clockwise, looking from the burner side, with the secondary air in the afterburner travels counterclockwise ensuring a good mixing in a short distance. Hardware selection for the MWP-75 was made based on state-of the-art technology and taking into account "over the road" applications. PCBs mixed with kerosene are fired in the primary combustor and the off |
