[0002] When conducting ash analysis, the ground coal sample needs to be placed in a combustion box and the ash content is determined by high-temperature burning. This process requires the sample to be completely burned under specific high-temperature conditions so that the organic matter decomposes and leaves inorganic minerals. Depending on the type and purpose of coal, the slow ash method or the fast ash method may be used to determine the ash content. Ash content is the main factor in testing coal quality and an important part of coal pricing. Therefore, the determination and calculation of coal calorific value cannot be ignored, and the heat detection of coal requires the use of a detection box for detection;

After the water injection is completed, the combustion box body 1 is started through the control panel 7 for combustion and heating, and the coal on the top of the water inlet pipe 3 is burned. After combustion, the debris after combustion will fall into the collection frame 801 through the holes of the isolation net 13.
