Classification4.1 There are four grades of industrial burner fuel contain-ing recycle
35、d lubricating oils covered by this specification.These grades may or may not correlate directly with similargrades in other ASTM standards. The RFO designation iden-tifies them as Reprocessed Fuel Oils. The usage descriptions ofeach grade may not describe all the uses, but are included asgeneral inf
36、ormation. The four grades are described as follows:4.1.1 Grade RFO4Primarily a blend of used lubricatingoils and distillate or a reprocessed distillate product derivedfrom used oil. It is intended for use in pressure atomizingindustrial burners with no preheating. This grade of recycledoil fuel is u
37、sed in many medium capacity industrial burnerswhere ease of handling justifies the higher cost over the heavierused oil fuels.4.1.2 Grade RFO5LA straight (100 %) used lubricatingoil blend or a used lubricating oil and distillate blend fuel ofintermediate viscosity, heavier than Grade RFO4. It is int
38、endedfor use both in pressure-atomizing industrial burners notrequiring higher cost distillates and in burners equipped toatomize oils of higher viscosity with or without pre-heating. Itspermissible viscosity range allows it to be pumped andatomized at relatively low-storage temperatures.4.1.3 Grade
39、 RFO5HA straight (100 %) used lubricatingoil blend or a used lubricating oil and residual blend fuel,heavier than Grade RFO5L. It is intended for use in industrialburners equipped with devices that atomize oil of higherviscosity than domestic burners can handle. Preheating may benecessary in some ty
40、pes of equipment for burning and in colderclimates for handling.4.1.4 Grade RFO6A high-viscosity used lubricating oiland residual blend fuel, heavier than Grade RFO5H. It isintended for use in large industrial heaters and may requirepreheating in the storage tank to permit pumping. Additionalpreheat
41、ing at the burner may be necessary to permit satisfac-tory atomization. The extra equipment and maintenance re-quired to handle this fuel usually preclude its use in smallinstallations.5. General Requirements5.1 The fuel oils specified herein shall contain a minimumvolume of 25 % of used lubricating
42、 oil-derived products, thebalance being a Specification D396 fuel oil or suitable refinerystocks.5.2 The fuel oils shall be homogeneous fluids consistingprimarily of hydrocarbons. Fuel oils containing residual com-ponents shall remain uniform in storage and shall not separateby gravity or aging into
43、 layers in normal operating conditions.NOTE 4Prolonged storage or equipment down time may necessitatecirculation of the fuel oil in-tank to prevent such separation.5.3 The fuel oil shall not contain excessive amounts oforganic or inorganic acids, or both, and shall be free of solid orfibrous matter
44、that could cause system handling or maintenanceproblems. The buyer and seller should agree on any require-ments for particle size.NOTE 5The fuels defined by this specification are appropriate only forburners capable of handling and combusting fuels with potentially highermetals and ash content.6.
