Show CURRENT STATUS A cyclonic incineration demonstration system capable of incinerating 60 gallons per hour of waste is currently being fabricated by York-Shipley, Inc. Scheduled start-up of the demonstration system is t-1arch 1984. Testing and evaluation of this system is expected to be followed by a 300 gph industrial-size cyclonic incineration system. A schematic of the demonstration and commercial systems is shown in Figure 5 and a description of the system's major components is given below. Incinerator Chamber The incinerator chamber will be water cooled. The calculated total water flow will be 22 gpm at a 6T of 54°F and using a velocity of 4.9 ft/sec. The cooling annulus width is 1/2 inch. In general, the same type of construction as used on the pilot unit has been repeated. Harbison-Walker's Ruby plastic refractory will be used as well as the 1/2 inch diameter anchoring studs. For system "start-up," an eclipse nozzle mixing pilot will be used. An air-cooled ultraviolet scanner will be used to monitor the flame along with a solid-state flame control. The base of the incinerator will be basically the same as the pilot unit with the exception that the slag/ash removal port is located at the side of the base. Temperature monitoring inside the base will utilize a type K shielded thermocouple. Major parameters of the incinerator chamber for the demonstration and commercial units are: Waste Consumption, gph Natural Gas Firing Rate, CF / h Cooling Water Flow, gpm Inside Diameter, inches Height, inches Waste-Handling Subsystem Demonstration Unit 60 720 22 27-1/4 54-1/2 Industrial Unit 300 3600 64 46-1/2 93 The pump that will supply waste to the incinerator is a Model "0" Cresaco pump with rubber impellers. The pump is mounted on a stainless baseplate and driven through a scoopmounted gear reducer. The motor is a 1/2 hp AC motor, which the speed and, hence, pump capacity can be varied through a variable frequency AC drive, either manually or automatically through a flow-control loop. The loop begins with a micro motion flowmeter in the waste conveying line which sends a signal back to a flow-recording controller. The recorder, in turn, varies the pump speed to maintain a desired preset flow rate. The inlet of the pump is directly connected to a 4000 gallon storage tank. The incinerator is located approximately 135 feet from the pump which allows heating the waste on the way to the incinerator with a triple jacketed line heated with hot water at approximately 43 |
