Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] The test method of the influence of space and multi-component gas on the tendency of coal spontaneous combustion in this embodiment comprises the following steps:
[0023] 1) adjust the height of the inner cavity of the reactor;
[0024] 2) Put the piled coal sample into the reactor;
[0025] 3) Pass three kinds of gases with specified components, fluxes and concentrations through the three gas inlets on the reactor;
[0026] 4) Adjust the temperature of the oil bath outside the reactor so that the oil bath temperature is always equal to the self-heating temperature of the coal sample;
[0027] 5) Turn on the fan arranged on the end surface of the gas inlet side of the reactor to control the ventilation state in the reactor;
[0028] 6) Collect the inner cavity temperature and cavity wall temperature in various places in the reactor through th...
