Estimation of coal proximate analysis factors and calorific value by multivariable regression method and adaptive neuro-fuzzy inference system (ANFIS) [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2017
The proximate analysis is the most common form of coal evaluation and it reveals the quality of a coal sample. It examines four factors including the moisture, ash, volatile matter (VM), and fixed carbon (FC) within the coal sample.

The effect of adding rice straw charcoal to the processing of bio-pellet from cacao pod husk

open access: yesAdvances in Food Science, Sustainable Agriculture, and Agroindustrial Engineering, 2020
Cacao pod husk and rice straw charcoal are potentially transformed into bio-pellet because of their high calorific value. Cocoa pod husk and rice straw charcoal has a calorific value of 4974.837 cal/g and 3569.837 cal/g, respectively. This research aimed

Calorific Value of Wood Fuel

open access: yesBulletin of Higher Educational Institutions. Lesnoi Zhurnal (Forestry journal), 2017
Древесная биомасса является природным ресурсом многоцелевого назначения. Наиболее востребованы в качестве твердого биотоплива древесные гранулы и брикеты, изготавливаемые из отходов переработки древесины и характеризующиеся высокой энергоемкостью. Теплота сгорания является нормированным показателем качества топлива и основным критерием оценки его ...

Predicting Calorific Value of Thar Lignite Deposit: A Comparison between Back-propagation Neural Networks (BPNN), Gradient Boosting Trees (GBT), and Multiple Linear Regression (MLR)

open access: yesApplied Artificial Intelligence, 2020
Calorific value provides a strong measure of useful energy during coal utilization. Previously, different AI techniques have been used for the prediction of calorific value; however, one model is not valid for all geographic locations.
