Prediction of Gross Calorific Value of Coal using Machine Learning Algorithm

International Journal for Research in Applied Science and Engineering Technology, 2022
Abstract: The rising number of occurrences of coal grade slippage among coal suppliers and users is causing worry in the Indian coal industry.One of the most important metrics for determining coal quality is the Gross Calorific Value (GCV). As a result, good GCV prediction is one of the essential techniques to boost heating value and coal output.

Coal Calorific Value Prediction Based on Projection Pursuit Principle

TELKOMNIKA Indonesian Journal of Electrical Engineering, 2012
The calorific value of coal is an important factor for the economic operation of coal-fired power plant. However, calorific value is tremendous difference between the different coal, and even if coal is from the same mine. Restricted by the coal market, most of coal fired power plants can not burn the designed-coal by now in China.
