摘要
利用煤质快速分析系统对煤的低位热值进行分析,以指导生产。煤质快速分析系统是基于脉冲快热中子活化分析技术(PFTNA),主要由脉冲中子发生器和BGO(锗酸铋)探头构成,数据处理采用多元回归分析方法,较好地解决了元素间的干扰问题,测得煤的低位热量分析值Qnetar与化验值的误差<0.4MJ/kg。
The principle of pulse fast-thermal neutron analysis (PFTNA) is introduced. PFTNA is mainly composed of the pulsed neutron generator and the BGO detector. The low calorific value of coal is measured. The multiple linear regression method is applied to deal with data solving the interferential problem of multiple elements. The results show that the error of low calorific value by PFTNA comparing with the chemical analysis is less than 0.4 MJ/kg.
