How are additives used when coal testing equipment measures the calorific value of lower-calorie substances?

How to use additives when measuring calorific value? What is a fully automatic calorimeter used for? A fully automatic calorimeter mainly measures the calorific value of coal, oil, straw, coal gangue, shale, fly ash, slag, silt, tailings, food, garbage and other substances. However, the calorific value of some substances is relatively low, and when encountering this situation, mirror paper must be used to support combustion.

Attention to the use of calorimeters (additives).

Materials with known calorific value can be used as additives (benzoic acid, standard coal, mirror cleaning paper, etc.).

The coal sample to be tested is mixed evenly with the additive.

The sum of the weight of the coal sample and the additive is about 1 gram. The total calorific value cannot be less than 18000J, higher than 30000J.

The calorific value of the additive set by the system before the experiment is entered.

When testing, the weight of the additive should be entered into the corresponding column.

After the test, the microcomputer subtracts the heat of the additive itself.

When using additives, remember to enter the weight of the additive.
