Waste-Oil Boiler Firing Demonstration at Naval Weapon Center China Lake, California.

Abstract : The waste oil generated at Naval Weapon Center (NWC), China Lake, CA was fired in a 20,000-lb/hr steam boiler at NWC to determine the operational requirements for using it as a boiler fuel. Two series of tests were conducted using blends of this waste oil and commercial grade No. 6 fuel oil normally used for NWC boilers. The first series tested batch-blended oils, while the second series an in-line blending scheme. Six thousand gallons of waste oil was consumed and 440 boiler hours covering the full range of firing conditions were logged during the tests. Results show that the NWC waste oil can be satisfactorily fired either straight or in blends of any concentration with No. 6 fuel oil. Only minor adjustments to firing controls are sometimes required. No operational or environmental emission difficulties were encountered. (Author)
