1 metric ton (tonne) short tons. From GAR to NAR. The difference between net and gross as received (NAR v/s GAR) specific energy values is the latent heat of the water vapour which lowers the effective calorific value in the boiler. To convert from GAR to NAR for bituminous coals subtract approximately. mj/kg. 260 kcal/kg. 470 btu/lb.

How do you calculate inherent moisture in coal?

First, determine the weight of the object while wet. Using a scale, we find the object to be 20g while wet. Next, determine the weight while dry. After drying the object, we weigh it again and find that the weight is 10g. Finally, calculate the moisture content. Using the formula we find the moisture content to be 50%.

Moisture in Coal University of Kentucky

Asreceived moisture: Moisture (water) in a sample upon delivery to a lab. The same as asdelivered moisture. Also used as a recording standard (denoted as "ar" or "AR"). Asreceived (AR) moisture equals airdried loss moisture plus residual moisture (measured from the proximate analyzer).

Proximate Analysis an overview | ScienceDirect Topics

Total moisture includes airdry loss moisture and inherent moisture. Airdry loss moisture, which is not linked to organic matter, is the loss of weight resulted by drying at room temperature. Inherent moisture content is determined by heating an airdried coal sample at 105°110°C (221230°F) under specified conditions until a constant ...

Basis of coal CKIC

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

What is the difference between ADB and ARB in coal?

ADB AirDried Basis. In coal sample analysis, ADB neglects the presence of moistures other than inherent moisture while DB (drybasis) leaves out all moistures, including surface moisture, inherent moisture, and other moistures. ARB AsReceived Basis. It provides a rough estimate of the heating value of coal.

Net Calorific Value an overview | ScienceDirect Topics

If the ash content of the fuel is low and rather constant, the calculation can be based on the dry basis Eqn () with a typical value of q p,net; however, if the ash content varies quite a lot (or is high) for the specific biofuel then using the equation for dry and ashfree basis () with a typical value of q p,net,daf is preferable. 1 ...
