Glossary | Ares Asia Glossary 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.
An as fired sample can be reported on an As Received (AR) (how the lab received the sample and includes the total moisture), Air Dried Basis (ADB) also called As Determined Basis, Dry Basis, and ...
Summary. The proximate analysis of coal separates the products into four groups: (1) moisture, (2) volatile matter, consisting of gases and vapors driven off during pyrolysis, (3) fixed carbon, the nonvolatile fraction of coal, and (4) ash, the inorganic residue remaining after combustion. The proximate analysis of coal is presented as a group ...
Common recording standards (in alphabetical order): Airdried basis: Data or results are calculated to the moisture condition of the coal after being allowed to airdry (at room condition humidity). Usually denoted as "ad" or "AD." Asdetermined (airdried) basis: Usually denoted as "adm" or "ADM."
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 .

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.
Various terms in coal/steam coal and their meanings ADB = AIR DRIED BASIS ARB = AS RECEIVED BASIS NCV = Gross calorific Value kcal/kg (adb) GAD. 5800 5600 GCV basis ARB means basically cargo 6300 GCV basis ADB.
determination of moisture in the airdried material shall be made at the same time as the ash and volatile matter are determined. The results of proximate analysis are generally recorded as a percentage of the airdriedmaterial. The ash may be expressed on 'dry' basis. Volatile matter and fixed carbon may be expressed on 'dry'basis,
Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate electricity. It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel ...
ADB=Air Dried Basis ARB=As Received Basis. What gcv of coal is it when it's gar is 3600 to3800? GAR is ((100total moisture)/ (100inherent moisture)) x Calorific Value in ADB So all depends on ...
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 ...
