Embodiment 1
[0021] figure 1 It is a structural schematic diagram of the device for detecting the characteristics of the coal coking process in the coke oven of the present invention, as figure 1 As shown, the device for detecting the characteristics of the coal coking process in the coke oven of the present invention includes a coal sample heating system, a characteristic detection system, a light source adjustment system, an atmosphere system and a water cooling system.
[0022] The structure and connection relationship of the coal sample heating system are: heating furnace 5; there is a high-temperature furnace tube 3 inside the heating furnace 5, and a quartz window 10 is arranged at one end of the high-temperature furnace tube 3, and there is a frosted glass with a scale on the quartz window 10; The constant temperature zone in the tube 3 is provided with a sample substrate 7; the sample box 6 is arranged on the sample substrate 7 and faces the quartz window 10; The temperature contr...
Embodiment 2
[0028] In this embodiment, the device for detecting the characteristics of the coal coking process in the coke oven in Embodiment 1 is used for detection.
[0029] S0: Make the coal sample A to be tested: crush the coal A with an ash content of 13.11%, a fixed carbon content of 61.93%, a volatile matter content of 23.87%, and a moisture content of 1.09% to less than 0.05mm, and press it to grow under a pressure of 15MPa 20mm, 20mm wide, 15mm high block.
[0030] S1: Put the coal sample into the sample box and close to the movable baffle, then set the sample box containing the coal sample on the sample substrate, the material of the sample substrate is Al 2 o 3 , and set it in the constant temperature zone in the high-temperature furnace tube, then use the light source adjustment system to adjust the brightness of the light source, and adjust the lens accordingly, so that the digital camera can capture a clear image of the coal sample.
[0031] S2: Pass argon gas into the hig...
Embodiment 3
[0037] S0: Make coal sample B: crush coal B with an ash content of 16.27%, a fixed carbon content of 59.67%, a volatile matter content of 23.21%, and a moisture content of 0.85% to less than 0.05mm, and press it under 20MPa pressure to grow 20mm wide. 20mm, 15mm high block.
[0038] The material of the sample substrate used in this embodiment is SiO 2 , the inert gas introduced into the atmosphere system is helium, using the same detection methods S1-S4 as in Example 2, the maximum expansion rate of the coal sample is calculated to be 4.1% and the maximum expansion pressure is 3.12kPa.
