Study on the Influencing Factors of Automatic Oxygen Bomb Calorimeter for Measuring the Calorific Value of Coal Gangue
Based on GB/T 213-2008 Determination of Coal Calorific Value,four different ash content ranges of coal gangue were selected.A small oxygen bomb calorimeter was used to measure the calorific value of coal gangue under different combustion conditions,different sample weights,different oxygenation times,and whether it was a ground sample under isothermal conditions at 25℃.Through comparative experiments,the method of reducing the error in determining the calorific value of coal gangue has been verified.By measuring the calorific value of coal gangue,the rational utilization of its waste heat value can be achieved.
