Prediction of gross calorific value from coal analysis using decision tree-based bagging and boosting techniques [PDF]

Heliyon, 2023
The calorific value of any fuel is one of the crucial parameters to grade fuel's burning capability. The bomb calorimeter has historically been used to calculate coal's gross calorific value (GCV).
