Calorimeter experiment time is too long:
1. Calorimeter barrel level is not enough solution:
(1) Drain valve leakage, cleaning or replacement of the drain valve (2) Bucket is not full of water Manually pump the bucket full Reason: Stirring efficiency is not enough Solution:
(1 Stir) Motor does not work, replace motor (2) Stir motor and stir rod are not connected well, then stir rod (3) Stirrer rod position is not correct, adjust the fixed sleeve (4) The stirring blade angle is not correct, the blade is adjusted to 45 degrees Angle (5) sample calorific value is too low, add additives 3. Problems to be Noted When Using Additives: Calorimeters 1) Benzoic acid, standard coal, and mirror paper with known calorific value can all be used as additives.
2) The tested coal sample and additives should be mixed evenly.
3) The sum of the weights of the tested coal samples and additives should be about 1 gram, and the total calorific value should not be lower than 18000J, nor should it be higher than 30000J.
4) Before the calorimeter experiment, add the calorific value (J/g) of the additive to the calorific value of the additive in the system setting. When testing, add the weight of the additive to the corresponding column. At the end of the test, Micro Opportunity automatically subtracts the calorific value of the additive from the result.
4. The probe is not in the correct position and is adjusted to the correct position.
5. Scale around the probe and remove it for cleaning.
