Prediction method of coal calorific value based on quantile regression

open access: yesGong-kuang zidonghua, 2022
At present, the traditional linear regression model is mainly used to predict the calorific value of coal. But it is difficult to express the complex relationship between independent variables and dependent variables.

Performance of Fuzzy Inference System for Calorific Value Predicting by Using The Mamdani Method

open access: yesIndonesian Journal of Applied Physics, 2021
It is well known that the energy content of fuel is characterized by its calorific value which is usually measured by using a bomb calorimeter. In many analysis, the calorific value is usually related with the proximate analysis results.

Prediction of Calorific Value of Biomass from Proximate Analysis

open access: yesEnergy Procedia, 2017
Abstract Biomass is one of the renewable and sustainable energy sources that does not lead greenhouse gas emissions. Efficient use of biomass energy will help to solve problems resulting from fossil fuels. However, the main concern relevant to use of this energy is mainly related to low calorific value of biomass.

Prediction of the Calorific Value of Coal Deposit Using Linear Regression Analysis

open access: yesEnergy Sources, Part A: Recovery, Utilization and Environmental Effects, 2013
Coal quality has prime importance in the production of energy, and thus determining the quality is useful in planning of coal deposit. The prediction of coal quality, especially calorific value, is one of the important parameters. The estimation of calorific value is a complicated problem in coal deposits.

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

open access: yesHeliyon
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).
