1、Designation:D2014/D2014M19Standard Test Method forExpansion or Contraction of Coal by the Sole-Heated Oven1This standard is issued under the fixed designation D2014/D2014M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of l
2、ast revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers a large-scale laboratory test forobtaining information on the expansion or contraction of coalor coa
3、l blends during carbonization under specified conditions.This test method is applicable in the examination of coals orcoal blends intended for use in the manufacture of coke.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach
4、 system are not necessarily exact equivalents;therefore,toensure conformance with the standard,each system shall beused independently of the other,and values from the twosystems shall not be combined.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its u

7、Gross Sampleof CoalD3302 Test Method for Total Moisture in Coal3.Summary of Test Method3.1 During the test,a measured thickness of coal about102 mm 4 in.is heated from the bottom surface while a forcecorresponding to 15.17 kPa 2.20 psi is applied to the topsurface through a piston.At the end of the
8、test,the thickness ofthe coke is measured by observing the final position of thepiston.4.Significance and Use4.1 The values determined in this test method indicate towhat extent a given coal or coal blend will expand or contractduring the carbonization process when evaluated in terms ofpertinent exp
9、erience with other coals and coal blends andprocessing conditions used in commercial-type coke ovens.5.Apparatus5.1 Test Oven Assembly,consisting of the following:eithera single-chamber oven having approximately 280 mm 11 in.width,610 mm 24 in.length,and 280 mm 11 in.depth,or adouble-chambered oven
10、with two chambers each having ap-proximately 280 mm 11 in.width,length,and depth;aheating system to heat the charge(s)unidirectionally throughthe sole according to a controlled program;piston(s)arrangedso that a constant load may be applied to the top surface of thecharge;and suitable instrumentatio
11、n so that appropriate tem-peratures and the position of the piston(s)may be measured.The auxiliary equipment includes apparatus facilitating thecharging of the oven in a standard manner.The verticalpartition of the double-chambered oven may be of 51 mm2 in.firebrick tile or equivalent.5.1.1 Carboniz
12、ation Chamber:5.1.1.1 The sole shall be of silicon carbide tile,about 40 mm1.5 in.thick,305 mm 12 in.wide,and extending approxi-mately 75 mm 3 in.beyond the carbonization chamber at thefront and back.Side,front,and back walls should be 40 mm1.5 in.firebrick tile or equivalent.It is appropriate to ke
