Значение и использование

5.1 The combustible carbon content of solid residues is used to calculate efficiency of fuel combustion in boiler furnaces and similar combustors.

5.2 Combustible carbon values are also used to determine the residual fuel value of incompletely combusted/reacted coal and coke in other reactors that consume carbonaceous fuels (examples include fluidized bed furnaces and liquefaction, gasification and pyrolysis reactors).

5.3 The combustible carbon content of flyash is an important parameter in the use of flyash as a cement additive.

Область применения

1.1 Thistest method covers the determination of total, combustible, andcarbonate carbon remaining in the solid byproducts of combustionfrom boiler furnaces and similar reactors, including ash, flyash,char, slag, and similar materials.

1.2 Thistest method is intended for the use of industry to determine theperformance of boiler furnaces and similar combustion reactors andaid in determining the quality of the solid residue fromcombustion.

1.3 Thistest method comprises the use of any of several methods todetermine total carbon content combined with any of several methodsto determine carbonate carbon, and the calculation, by difference,of the combustible carbon remaining in a sample.

1.4Alternatively, this test method applies to the determination oftotal carbon remaining in a material after acidification withstrong acid to evolve carbonate carbon. In this case, thecombustible carbon is the total carbon measured in the sample afteracidification.

1.5 Thevalues stated in SI units are to be regarded as standard. Non-SIunits, if provided, are for information only and are containedwithin parentheses.

1.6This standard does not purport to address all of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety,health, and environmental practices and to determine theapplicability of regulatory limitations prior to use.

1.7This international standard was developed in accordance withinternationally recognized principles on standardizationestablished in the Decision on Principles for the Development ofInternational Standards, Guides and Recommendations issued by theWorld Trade Organization Technical Barriers to Trade (TBT)Committee.
