The simplest test to evaluate whether a coal is suitable for production of coke is the free swelling index test. It involves heating a small sample of coal in a standardized crucible to around degrees Celsius ( °F).

The free swelling index in British Standards Index (BSI) nomenclature (the crucible swelling.

This test method is a small-scale test for obtaining information regarding the free-swelling properties of a coal. The results may be used as an indication of the caking characteristic of the coal when burned as a fuel.

This test is not recommended as a method for the. Studies using the RF method in the field of coal have mostly focused on predicting coal properties, such as calorific value [30], free swelling index [31, 32], coal grindability index [ The mineral content of coal affects the type of ash that will be produced on combustion.

Despite the same volatile matter content, the Okobo 1 FSI is with ash content of while Okobo 2 FSI. Indian Standard:, Determination of Hargrove Grindability Index of Coal, Bureau of Indian Standards, New Delhi.

Indian Standard Part 1,Methods of Test for Coal and Coke: Proximate analysis (Second Revision), Bureau of Indian Standards, New Delhi. Ultimate analysis parameters. Ultimate analysis of coal and coke involves the determination of carbon, hydrogen, nitrogen, sulfur (total sulfur), and oxygen by difference (ASTM D).As with fixed carbon, calculated oxygen contains a huge uncertainty resulting comes from the summation of all the errors incurred during the determinations of other components and, as a result, is not an Cited by: The free swelling index (FSI) is reported on a scale of 1 to 9 in increments of 1/2.

Coals having a FSI from 1 to 3 are generally referred to as free burning, from 3h to 5 as moderately caking, and from 5% to 9 as strongly caking. Caking characteristics have little or no effect on the performance of spreader stokers.

The free-swelling index is quite important in differentiating between groups in the classification of coals; it also gives considerable information on the combustion characteristics of coal.

The test consists of heating the coal under prescribed conditions and comparing the residue or. Other Coal Properties Analysis of the test coal was conducted by Commercial Testing and Engineering Company, Western Division, located in Denver, Colorado.

Analyses were performed according to standard proced- ures to measure proximate and ultimate analyses, ash fusion temperature, and free swelling index.

(15) Bernas, B. In this study, an in-depth investigation of this commonly used method has been accomplished for the analysis of pyrolysis oil.

Several commonly used internal standards for 31 P NMR have been examined by in situ monitoring. The results indicated that endo-N-hydroxynorbornene-2,3-dicarboximide (NHND) is not stable after a long period of.

However, the free swelling test is simple to perform, does not require sophisticated instrumentation, and provides a reasonable measure of the caking properties of coal; therefore it is widely used for assessing coals for coke-making.

The free swelling index generally increases with rank among relatively fresh bituminous coals with less than 9%. Biomass is relatively cleaner than coal and is the only renewable carbon resource that can be directly converted into fuel. Biomass can significantly contribute to the world’s energy needs if harnessed sustainably.

However, there are also problems associated with the thermal conversion of biomass. This paper investigates and discusses issues associated with the thermal conversion of coal and Cited by: An Investigation of a Laboratory Test for Determination of the Free-Swelling Index of Coal, U.S.
