34、two applications:(a) industrial furnacesintegral components of manufacturing processes that provide direct heating, for example, inaggregate, cement, lime, or phosphate kilns; coke ovens; or blast, smelting, melting, refining, or drying ovens.(b) industrial boilerslarge indirect heating units that t
35、ransfer thermal energy to water or other fluids or gases for use inheating in industrial settings and in manufacturing processes3.3.2 reprocessing, n in petroleum product recycling, the preparation of used oil to be suitable as a fuel.3.3.2.1 DiscussionReprocessing includes procedures such as settli
36、ng, filtration, blending, distillation, and chemical treatment.4. Classification4.1 There are four grades of industrial burner fuel containing recycled lubricating oils covered by this specification. Thesegrades may or may not correlate directly with similar grades in other ASTM standards. The RFO d
37、esignation identifies them asReprocessed Fuel Oils. The usage descriptions of each grade may not describe all the uses, but are included as general information.The four grades are described as follows:4.1.1 Grade RFO4Primarily a blend of used lubricating oils and distillate or a reprocessed distilla
38、te product derived from usedoil. It is intended for use in pressure atomizing industrial burners with no preheating. This grade of recycled oil fuel is used in manymedium capacity industrial burners where ease of handling justifies the higher cost over the heavier used oil fuels.4.1.2 Grade RFO5LA s
39、traight (100 %) used lubricating oil blend or a used lubricating oil and distillate blend fuel ofintermediate viscosity, heavier than Grade RFO4. It is intended for use both in pressure-atomizing industrial burners not requiringhigher cost distillates and in burners equipped to atomize oils of highe
40、r viscosity with or without pre-heating. Its permissibleviscosity range allows it to be pumped and atomized at relatively low-storage temperatures.4.1.3 Grade RFO5HAstraight (100 %) used lubricating oil blend or a used lubricating oil and residual blend fuel, heavier thanGrade RFO5L. It is intended
41、for use in industrial burners equipped with devices that atomize oil of higher viscosity than domesticburners can handle. Preheating may be necessary in some types of equipment for burning and in colder climates for handling.4.1.4 Grade RFO6Ahigh-viscosity used lubricating oil and residual blend fue
42、l, heavier than Grade RFO5H. It is intended foruse in large industrial heaters and may require preheating in the storage tank to permit pumping.Additional preheating at the burnermay be necessary to permit satisfactory atomization. The extra equipment and maintenance required to handle this fuel usu
43、allypreclude its use in small installations.5. General Requirements5.1 The fuel oils specified herein shall contain a minimum of 25 % (volume) of used lubricating oil-derived products, thebalance being a Specification D396 fuel oil or suitable refinery stocks.5.2 The fuel oils shall be homogeneous f
44、luids consisting primarily of hydrocarbons. Fuel oils containing residual componentsshall remain uniform in storage and shall not separate by gravity or aging into layers in normal operating conditions.NOTE 4Prolonged storage or equipment down time may necessitate circulation of the fuel oil in-tank
45、 to prevent such separation.5.3 The fuel oil shall not contain excessive amounts of organic or inorganic acids, or both, and shall be free of solid or fibrousmatter that could cause system handling or maintenance problems. The buyer and seller should agree on any requirements forparticle size.NOTE 5
46、The fuels defined by this specification are appropriate only for burners capable of handling and combusting fuels with potentially highermetals and ash content.D6448 1436.
