A brief discussion on the calibration key points of oxygen bomb ash analyzer
In order to solve the problem of long time for coal ash detection,the development of new equipment oxygen bomb ash detector.For the equipment mainly contains weighing system and combustion system,the principle is to put a certain amount of samples in a special oxygen bomb filled with a certain pressure of oxygen combustion,to the quality of the residue of the mass of the coal sample quality of the mass fraction of the coal sample as a coal sample of the ash.According to the technical parameters of the instrument,the ash detection of the instrument was calibrated by using the standard substances for analysis of physical properties and chemical composition of coal,and the calibration results showed that the repeatability of the sample detection was 0.09％～0.28％,and the uncertainty of the measurement results of the display value error was 0.4％～0.9％.
