between the untreated and analyzed samples. One of the variables influencing the performance of a coal-fired power plant is the moisture content of the raw coal which is directly proportional to its calorific value. There are many moisture concepts in coal analysis and its impact on power plant performance as stated below -

• As-received basis (ar): The basis for analytical data calculated to the moisture condition of the sample as it arrived at the laboratory and before any processing or conditioning. If the sample has been maintained in a sealed state so there has been no gain or loss, then the as-received basis is equivalent to the moisture basis as sampled.

What is the difference between ARB and ADB? ARB puts all variables into consideration and uses the total weight as the basis of measurement. ADB (air-dried) basis neglect the presence of moistures other than inherent moisture unlike ARB which uses total moisture. This results in different measured GCV on different Basis.
Difference in GCV and UHV of coal? GCV, gross calorific value, is the quantity of heat produced by combustion. UHV, useful heat value, is the gradation of non-coking coal.
Reduction in GCV shall be computed as per the difference between weighted average GCV- ARB of loading end as reported by TPSA (results, including that of referee) and GCV-ARB determined at the plant end for the Batch. Example: Assume Base price is INR 5000 PMT for GCV (ARB) 4900 Kcal/kg but received GCV (ARB) is 4750 Kcal/kg.
calculating other measured quantities to the as received basis (ARB) and as dry basi s (ADB). T otal moisture is important in assessing and controlling the commercial processin g of coals.
Fixed carbon is a calculated value of the difference between 100 and the sum of the moisture, ash, and volatile matter where all values are of the same moisture reference base. ... A represents the ash content, the subscripts ARB, ADB and DB represent the values related on as received basis, air dried basis and dry basis. Table …
Its analysis, wt % on an air dried basis (as was used for the experiments) is the following: moisture = 3.6, ash = 22.3, volatile matter = 25.9, G.C. V. = 5664 Kcal/K, C …
The difference between the above three conditions is the proportion of the Moisture. The Calorific Value and other coal constituents analysed in the laboratory on 'Air Dried' basis is converted to 'As received' or 'As Fired' basis proportional to the moisture content. Search.

The gross calorific value (GCV) of dry bagasse has a mean value of 19605 kJ/kg. The gross calorific value (GCV) of wet bagasse is based on the composition of wet bagasse. Water has no calorific value and it also absorbs heat being vaporized during combustion. The combustion reactions of bagasse as a fuel are as given in Table 3 ( Mugadhi 1999 ...

ADB – Air-Dried Basis. In coal sample analysis, ADB neglects the presence of moistures other than inherent moisture while DB (dry-basis) leaves out all moistures, including surface moisture, inherent moisture, and other moistures. ARB – As-Received Basis. It provides a rough estimate of the heating value of coal.

The gradation of non-coking coal is based on Gross Calorific Value (GCV), the gradation of coking coal is based on ash content and for semi coking /weakly coking coal it is based on ash plus moisture content, as in vogue as per notification. Grades of Coking Coal. Grade. Ash Content. Steel Grade - I. Not exceeding 15%.
The term '5,500 NAR' refers to the net calorific value (heating value) of the coal in kilocalories per kilogram. S&P Global Commodity Insights also publishes the first ever daily ash assessment which is a normalization tool for use within the 17-23% ash range assessed. The new price and ash differential assessments provide thermal coal ...
