Coal quality analysis instruments - Calorimeter phenomenon

Reasons for coal quality analysis instruments and calorimeters

Coal quality analysis instruments Calorimeter processing

1.Oxygen bomb leakage

Aging or wear of rubber sealing rings

Replace the sealing ring

2.点火失败

1.Misfire

1.Check if the wiring is properly connected, if the oxygen warhead is in good contact with the ignition cap, and if the inner cylinder of the oxygen bomb is properly placed

2.Wet sample

2.Oxygenation too fast splashing wet sample

3.Poor contact between ignition wire or cotton thread and the sample

3.Reinstall the sample

4.Two electrodes are too dirty

4.Sanding the electrodes with sandpaper

5.Ignition cap oxidation

5.Sandpaper the ignition cap oxide

6.Short circuit between two electrodes and crucible (in this case, it is easy to burn the crucible and electrodes)

6.Replace the electrode or crucible and reinstall the sample

3.试样燃烧不完全

1. The sample is not flammable

2. Insufficient oxygen or insufficient oxygen pressure

用擦镜纸包好试样延长充氧时间，更换氧气瓶

4.Excessive increase in humidity and high calorific value after ignition

1.The mixer does not rotate

1.The mixing shaft is stuck and the circuit is not connected

2.Mixing blade detachment

2.Insert a cotton thread into the nylon rod hole connected to the mixing shaft and reinsert it

5.The experiment has not ended for a long time

Excessive ambient temperature

Adjust the water temperature of the outer cylinder to be basically consistent with room temperature, or lower the indoor temperature

6.Leakage during oxygenation

Aging or wear of sealing ring during oxygenation

Replace the sealing ring
