Lower Heating Value Estimation of Coal Gangue through Proximate Analysis Data Based on GB/T 212-2008

Abstract:

The calorific value of coal gangue is an important indicator to assess its quality for comprehensive utilizations. Although the heating values can be measured experimentally with a Bomb calorimeter, an easier and faster approach within an acceptable tolerance is in great demand. Herein, we use an alternative approach to estimate the heating value based on proximate analysis data, which are measured under the instruction of GB/T 212-2008. The lower heating values of coal gangue samples we collected range from 2307 to 8309 kJ/kg, which are key information for the use of coal gangue in principle. We conclude that the sample with calorific value of 8309 kJ/kg can be used as formal fossil fuel; another sample of 5799 kJ/kg can be used for thermal power generation, while the other four are not worth for fuel.
