Product Description

     The spontaneous combustion tendency of coal, that is, the difficulty of coal spontaneous combustion, is a manifestation of coal's low-temperature oxidation and one of its inherent properties. Coal from different coal seams and mines has different spontaneous combustion tendencies The tendency of coal spontaneous combustion is the only basis for the classification of coal mine fire prevention and extinguishing levels, and all fire prevention and extinguishing technologies and measures are based on the identification of coal spontaneous combustion tendency. Therefore, scientifically identifying coal spontaneous combustion tendency is crucial for mine fire prevention and extinguishing and coal storage and transportation processes

The ZRJ-2000 coal spontaneous combustion tendency tester is a fully automatic tester designed and manufactured entirely based on current national and industry standards
