Abstract：Coal-fired quality detection samples may be affected by external environment such as humidity and temperature during collec-tion and storage,resulting in low accuracy of coal-fired quality detection.Therefore,a coal-fired quality detection method based on atom-ic emission spectrum analysis technology was studied.Firstly,a coal-fired quality detection database was built to store and manage the quality data of coal samples;then,by collecting coal samples and using atomic emission spectrum analysis technology,the content of its key elements was determined,on this basis,the concentration of coal-fired was further calculated,so as to achieve a comprehensive de-tection of coal-fired quality.The experimental results show that in the determination of fixed carbon,air-dried ash,air-dried volatiles,air-dried high calorific value,air-dried moisture,air-dried total sulfur,air-dried hydrogen,air-dried oxygen and air-dried nitrogen,the results of this method are not only lower than the critical value of 95％confidence precision,but also have obvious advantages compared with the other two methods.This shows that the method has high accuracy and reliability in coal-fired quality detection,and can better reflect the real quality of coal-fired samples.
