Calorimeter

1, 2500 type coal chemical analysis equipment calorimeter ordinary thermostatic barrel inner cylinder water about 2000g, for different cylinders, water volume can be different, required to meet the national standard to cover the oxygen bomb cover in 10 ~ 20mm, with oxygen bomb portable oxygen bomb At this time, the hook of the oxygen bomb hook can be put into the water. Under this premise, an easy-to-remember number can be used. Calorimeter training materials 19

2, the specific operation can be carried out according to the following steps: the oxygen bomb into the inner cylinder, poured into distilled water or deionized water, over the oxygen bomb cover 10mm, and less than 20mm. Then remove the oxygen bomb, the cylinder with water Weighing on an electronic platform scale (do not have to weigh water alone to reduce the chance of an error). For example, if the weight is 2728g, then 28g of water can be removed, and then 2700g can be weighed each time. This ensures that it meets the national standard and is easy to remember.

3. For dual-control calorimeters, under the premise of ensuring compliance with the national standard, it is advisable to re-fetch the same data with the two inner cylinders. Otherwise, it is easy to remember to mix them during use because the water depth of 10 mm can be adjusted completely. can do.
