[0002] Pulverized coal particle size testing requires extracting samples for particle size analysis, enabling subsequent particle size testing. Regular sampling provides representative samples for particle size analysis and chemical composition testing. This data helps optimize the combustion process, improve thermal efficiency, reduce pollutant emissions, and ensure compliance with relevant environmental standards. Furthermore, sampling can help identify trends in pulverized coal and enable timely adjustments to production processes, thereby improving overall production efficiency and economic benefits.
