Title:
EXPERIMENTAL PLATFORM FOR MEASURING COAL SPONTANEOUS COMBUSTION CHARACTERISTIC PARAMETERS
Document Type and Number:
WIPO Patent Application WO/2022/047835
Kind Code:
A1
Abstract:
An experimental platform for measuring coal spontaneous combustion characteristic parameters, which belongs to the field of coal spontaneous combustion experimental technology, and comprises: an intelligent temperature-controlled reaction cabinet (5); a gas supply assembly, which comprises a plurality of gas supply apparatuses (1); a gas distribution instrument (2), the gas supply apparatuses (1) all being in communication with the gas distribution instrument (2), and the gas distribution instrument (2) being in communication with the inside of the intelligent temperature-controlled reaction cabinet (5); a suspended-type weighing apparatus (12), which is arranged at the top end of the intelligent temperature-controlled reaction cabinet (5); a suspended basket (8), the suspended basket (8) being connected to the suspended-type weighing apparatus (12); a gas chromatograph (14), which is in communication with the inside of the intelligent temperature-controlled reaction cabinet (5); an infrared thermal imaging system; a temperature sensing assembly, which is arranged within the intelligent temperature-controlled reaction cabinet (5), and which comprises an ambient temperature sensing apparatus (10) and a coal sample temperature sensing apparatus (9); and computers (16). The present experimental platform is able to simulate the environment in a mine, and can dynamically capture characteristic parameters during coal spontaneous combustion such as coal mass, gas products, and heating rates for various marker points in a coal sample.
