working principle. The HZ2681 automatic industrial analyzer is designed according to the industrial analysis principle of GBT212-2008 coal. The sample is automatically weighed at a certain temperature and time and the moisture ash and volatile content are calculated based on the remaining mass of the sample and the carbon is fixed.

Ash content one of the important environmental concerns can be determined by massing the residue remaining after burning a sample of coal under controlled conditions. Duplicate results may be necessary for increased accuracy. Difficulty may be experienced in securing satisfactory determinations of ash for coal unusually high in calcite and.

Coal is ranked from lowest to highest lignite bituminous and anthracite. The lower the moisture and ash content the higher the rank. Activity Duration 2 to 3 class periods. Objective When students complete this activity they will be able to. demonstrate how a proximate analysis of coal is determined using actual measurements and.

Oct 07 2019 Ash yield is measured to determine how much material remains called ash residue after a coal is combusted. Ash yield is measured directly in an automated proximate analyzer or ashing furnace. Results are presented in weight percent. The ash yield of a coal sample is the amount of material remaining after combustion.

The AshScan measures the combined total of these elements which directly correlates to the total ash content in coal. The DUET technique uses two radioactive sources; Am-241 and Cs-137. Am-241 is a low energy gamma radiation. Absorption of Am-241 gamma rays occurs due to the presence of Si Fe Al and Ca and the amount of coal on the belt scale.

The difference in weight from the previous weighing is the fixed carbonFC. In actual practice fixed carbon. The FC derived by subtracting from 100 the value of moisture volatile matter and ash. 4. Proximate analysis. The proximate analysis indicates the percentage by weight of fixed carbon volatiles ash and moisture content in coal.
