Coal spontaneous combustion bundle tube monitoring

Coal spontaneous combustion bundle tube monitoringOverview

Using coal spontaneous combustion fire monitoring system to monitor O₂、N₂、H₂、CO、CO₂、CH₄、C₂H₄、C₂H₆、C₂H₂、SO₂By measuring parameters such as gas content, temperature, and pressure, the generation law of multi-component gas indicators during coal spontaneous combustion can be detected, providing technical and theoretical support for identifying the characteristics of early hidden dangers in coal spontaneous combustion. By measuring and analyzing the gas markers of spontaneous combustion fires, timely prediction and forecasting of temperature changes at the ignition point, judgment of coal surface oxidation, and providing scientific basis for the prevention and control of coal mine spontaneous combustion fires and mine gas accidents.

The DKCSF MS-1 series coal spontaneous combustion fire monitoring system from Duke Tech Company, based on infrared photoacoustic spectroscopy technology, has the advantages of high measurement accuracy, low detection limit, good real-time performance, in-situ online, and efficient measurement. It can be used as a monitoring system for coal spontaneous combustion large and small sample experimental platforms, and can also provide experimental conditions and improve coal production efficiency for scientific research in multiple directions such as coal fire disaster fire prevention and fire science.
