1、Designation:D441800(Reapproved 2011)Standard Practice forReceipt,Storage,and Handling of Fuels forGas Turbines1This standard is issued under the fixed designation D4418;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last
2、 revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers the receipt,storage,and handling offuels for gas turbines,except for gas turbines used in aircraft.It is i
3、ntended to provide guidance for the control of substancesin a fuel that could cause deterioration of either the fuel system,or the gas turbine,or both.1.2 This practice provides no guidance for either the selec-tion of a grade of fuel,a topic covered by Specification D2880,or for the safety aspects
4、of the fuel and fuel systems.Forexample,this practice does not address the spacings of storagetanks,loading and unloading facilities,etc.,and procedures fordealing with the flammability and toxic properties of the fuels.1.3 The values stated in SI units are to be regarded as thestandard.The values g
5、iven in parentheses are for informationonly.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory

8、entering the combustor(s)this term is used todesignate the fuel that is actually burned in the gas turbine.Fuel may actually be sampled at a point upstream from thepoint of entry into the combustor(s),provided the sample isrepresentative of the fuel actually entering the combustor(s).3.2 fuel contam
9、inantsin principle,are any fuel componentother than hydrocarbon oils.In the present context the con-taminants are foreign materials that make the fuel less suitableor even unsuitable for the intended use.The contaminants ofprimary interest are foreign materials introduced subsequent tothe manufactur
10、e of specification quality fuel.Hence they arematerials introduced in the distribution system(that is storagetanks,pipelines,tank,trucks,barges,etc.),or in the usersstorage and handling systems,or generated within thesesystems(rust generated in steel pipes and tanks by moist fuel,etc.).Contaminants
11、may be soluble or insoluble in the fuel.3.3 dissolved and free waterwater may be present in thefuel as dissolved water or as“free”(undissolved)water,orboth.The free water may be fresh or saline.Fresh water mayenter the fuel from steam coils in storage tanks,from conden-sation out of moisture-laden a
12、ir,or from leaking cooling coils.Saline water can enter the fuel during transportation in bargesor tankers.3.4 particulate solidsmay enter a fuel from the air(sus-pended dirt and aerosols)or from the distribution and storagesystems(rust,corrosion products,gasket debris,and so forth).3.5 metallic com
13、poundsmetals may be present as metalliccompounds in the fuel as a natural result of the composition ofthe crude oil and of the refining process.However,unlessspecial precautions are taken,additional metallic compoundscan be acquired during distribution and storage.A commercialproduct pipeline may co
