In order to study the possibility of fast analyzing the nitrogen conten in coal by D-D generator,the measuring equipment was designed and the Monte Carlo code was used to simulate the measuring results of the different coals.The absolute error of the nitrogen conten is no more than 0.08%,which meets the requirements of the standard GB/T 476-2001.The results indicated that it is feasible for D-D generator to analyze the nitrogen conten in coal.
