Significance and Use
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).
1.1 This test method covers the determination of total, combustible, and carbonate carbon remaining in the solid byproducts of combustion from boiler furnaces and similar reactors, including ash, flyash, char, slag, and similar materials.
1.2 This test method is intended for the use of industry to determine the performance of boiler furnaces and similar combustion reactors and aid in determining the quality of the solid residue from combustion.
1.3 This test method comprises the use of any of several methods to determine total carbon content combined with any of several methods to determine carbonate carbon, and the calculation, by difference, of the combustible carbon remaining in a sample.
1.4 Alternatively, this test method applies to the determination of total carbon remaining in a material after acidification with strong acid to evolve carbonate carbon. In this case, the combustible carbon is the total carbon measured in the sample after acidification.
