The invention discloses a testing test
system for a spectrum in the high temperature stage of the
spontaneous combustion inflammation process of
coal. The
system comprises a constant-temperature furnace, a
coal sample tank, a constant-temperature furnace lifting mechanism, an air supply
system and a
temperature control cabinet; the constant-temperature furnace comprises a constant-temperature furnace body, a constant-temperature furnace cover, a furnace
hearth and a heating unit; the
coal sample tank is composed of a tank body and a tank cover, and a coal sample tank
quartz glass observation hole is formed in the middle of the tank body; the constant-temperature furnace lifting mechanism comprises a support frame, lifters, a motor, shaft steering gears, first transmission shafts, second transmission shafts and lifting bases, and four guiding columns are installed on the support frame; the air supply system comprises an air source, a
drying tube, a pressure stabilizing valve, a gas
mass flow meter and a preheating tube. The invention further discloses a testing test system for the spectrum in the high temperature stage of the
spontaneous combustion inflammation process of the coal. According to the system and method, design is novel and reasonable, implementation, usage and operation are convenient,
temperature control is precise, the coal sample molecular structure change condition of the coal in the high-temperature
spontaneous combustion condition can be truly reflected, the practicability is high, and usage and popularization are convenient.
