1、 Basic function: Determine ash content
The ash analyzer determines the mass proportion of inorganic residues in the sample through high-temperature combustion method, X-ray induced spectroscopy analysis, or gamma ray penetration method. The specific process includes sample weighing, high-temperature oxidation (usually between 550 ° C and 1000 ° C), cooling weighing, and calculating ash percentage. For example, in the food industry, milk can be tested for water (reduced ash content) or raw materials can be judged for sediment contamination.
2、 Industry Applications and Quality Control
Food industry
Evaluate food hygiene and quality: Determine whether there is adulteration (such as milk mixed with water), raw material impurities contamination, or processing hygiene issues based on the total ash content.
Nutritional assessment: Indirectly evaluate the nutritional value of food through the mineral content (such as potassium and calcium) in ash.
Metal and Chemical Industry
Metal smelting: Determine the impurity content in iron ore and steel, optimize mineral processing and smelting processes.
Chemical products: testing the ash content of coal and petroleum coke to guide combustion efficiency and environmental control; Evaluate the quality of fillers in polymers and rubber.
Oil and Energy Industry
Petroleum product testing: According to ASTM D482 or GB/T 5085 standards, determine the ash content of petroleum to evaluate its performance (such as the influence of sulfide content on corrosion resistance).
Coal analysis: The ash content directly affects the combustion calorific value and environmental indicators, and energy utilization needs to be optimized through testing.
3、 Production process optimization and environmental monitoring
Real time online monitoring: For example, the X-ray induced slurry ash analyzer can detect the ash content of the slurry in the coal preparation plant in real time, guide the flotation process, improve the recovery rate of clean coal by 0.5% to 1%, and reduce waste discharge.
Environmental assessment: High ash fuel combustion produces more exhaust gas and waste residue, and the test data can provide a basis for the formulation of environmental standards.
