Estimation of gross calorific value of coals using artificial neural networks

Fuel, 2007
The gross calorific value (GCV) is an important property defining the energy content and thereby efficiency of fuels, such as coals. There exist a number of correlations for estimating the GCV of a coal sample based upon its proximate and/or ultimate analyses.

Accurate Measurements of the Gross Calorific Value of Methane by the Renewed GERG Calorimeter

Journal of Physical and Chemical Reference Data, 2019
Due to the commercial transfer of billions of cubic meters of natural gases, the knowledge of the gross calorific value (GCV) of the main natural gas components and, in particular, of methane, is of outstanding interest. On the basis of previous work carried out by a Groupe Européen de Recherches Gazières (GERG)–Physikalisch-Technische Bundesanstalt ...

Determination of Uncertainty in Gross Calorific Value of Coal Using Bomb Calorimeter

International Journal of Measurement Technologies and Instrumentation Engineering, 2011
A bomb calorimeter is an apparatus used for measuring the performance of coal in term of heat of combustion. Recent awareness has been created regarding uncertainty of measurement, due to mainly two reasons. Laboratory accreditation, which has steadily been on the rise, which requires a estimation of uncertainty of measurement particularly in the field
