37、red in certain jet aircraft is animportant performance requirement. The thermal stability mea-surements are related to the amount of deposits formed in theengine fuel system on heating the fuel in a jet aircraft.Commercial jet fuels should be thermally stable at fueltemperature as high as 163C (325F
38、). Such fuels have beendemonstrated to have inherent storage stability.X1.3.2 In 1973, Test Method D3241 replaced Method ofTest D1660, known as the ASTM Coker for the determinationof oxidative thermal stability. (See CRC Report 450, dated1969 and revised in 1972. See also Bert and Painters SAEpaper
39、730385.15) Today, a single pass/fail run with the tubetemperature controlled at 260C is used to ensure compliancewith the specifications minimum requirements. For a morecomplete characterization of a fuels thermal stability, a break-point can be obtained. The breakpoint is the highest tubetemperatur
40、e at which the fuel still passes the specificationrequirements of the tube deposit color and pressure differential.Normally, obtaining a breakpoint requires two or more runs atdiffering tube temperatures. Breakpoints are therefore not usedfor quality control, but they serve mostly for research purpo
41、ses.X1.4 CombustionX1.4.1 Jet fuels are continuously burned in a combustionchamber by injection of liquid fuel into the rapidly flowingstream of hot air. The fuel is vaporized and burned at nearstoichiometric conditions in a primary zone. The hot gases soproduced are continuously diluted with excess
42、 air to lower theirtemperature to a safe operating level for the turbine. Fuelcombustion characteristics relating to soot formation are em-phasized by current specification test methods. Other fuelcombustion characteristics not covered in current specificationsare burning efficiency and flame-out.X1
43、.4.2 In general, paraffin hydrocarbons offer the mostdesirable combustion cleanliness characteristics for jet fuels.Naphthenes are the next most desirable hydrocarbons for thisuse. Although olefins generally have good combustioncharacteristics, their poor gum stability usually limits their usein air
44、craft turbine fuels to about 1 % or less. Aromaticsgenerally have the least desirable combustion characteristicsfor aircraft turbine fuel. In aircraft turbines, they tend to burnwith a smoky flame and release a greater proportion of theirchemical energy as undesirable thermal radiation than the othe
45、rhydrocarbons. Naphthalenes or bicyclic aromatics producemore soot, smoke, and thermal radiation than monocyclicaromatics and are, therefore, the least desirable hydrocarbonclass for aircraft jet fuel use. All of the following measure-ments are influenced by the hydrocarbon composition of the15Bert,
