Comparison of nitrogen in coal by semi-micro Kjeldahl method and infrared thermal conductivity method
LONG Yaping
Abstract：In order to improve the test efficiency of nitrogen in coal,two determination methods of Nitrogen in coal in GB/T 19227-2008 and infrared thermal conductivity method were compared.The results showed two test methods were accurate, there was no significant difference of coal,which met the test requirements.However,it was more simple,high automation and operation safety with infrared and thermal conductivity method.
