automatic calorimeter for coal mining and chemical industry

Automatic Calorimeter provides key data for fuel performance evaluation, energy efficiency calculations and feedstock selection by accurately measuring the amount of heat released by the fuel during complete combustion.

Main Features of the Automatic Calorimeter

1. multi-probe temperature sensing technology: the automatic calorimeter adopts multi-probe temperature sensing technology, which is capable of real-time monitoring of the inner cylinder water temperature, the outer cylinder water temperature, the room temperature as well as the water temperature of the temperature-controlled water tank. The independent measurement of each probe ensures the accuracy of temperature monitoring, and effectively avoids the influence of temperature fluctuation on the experimental results under different experimental conditions.
2. constant temperature water circulation system: the automatic calorimeter is equipped with an efficient constant temperature water circulation system, which can realize two working modes: with temperature and fixed temperature. In the temperature mode, the water temperature follows the room temperature, which can solve the problem of temperature instability caused by the heat exchange between the outer cylinder water and the indoor air in the constant temperature mode and ensure the accuracy of the test.
3. automatic oxygen filling and deflating device: the automatic calorimeter is equipped with self-developed automatic oxygen filling and deflating device and automatic lifting and lowering mechanism of oxygen bomb, which does not require manual intervention for oxygen filling or deflating. The highly automated design makes the operation easier and improves the experimental efficiency and safety.
4. high-precision electronic measuring cup: using high-precision probe-type electronic measuring cup, no need to weigh the water manually, the system automatically measures the amount of water in the inner cylinder. The repeatable error of water volume measurement is less than 0.5g, which means more accurate water volume control, reduces testing errors and speeds up the experiment process at the same time.
5. ignition wire automatic identification function: this function can automatically determine the working status of the ignition wire, accurately identify the bad state, to avoid experimental errors due to ignition wire failure, to ensure the smooth progress of the experiment.
6. integrated laboratory management system: the automatic calorimeter can be connected with the laboratory management system to automatically upload and backup the test data, avoiding the risk of manual recording and data loss and improving the efficiency and safety of data management.
7. suitable for a variety of samples and accessories: the instrument can be equipped with special oxygen bomb and crucible and other accessories for solid waste samples to meet the testing needs of different samples. In addition, it can also be equipped with oxygen bomb gas collection device to collect and analyze the gas generated in the oxygen bomb.

Working Principle

Automatic Calorimeter determines the calorific value of a sample by measuring the amount of heat released when the sample is completely burned in an oxygen bomb. The sample is first placed in a sealed oxygen bomb, filled with oxygen, the instrument through the electric ignition device to ignite the sample. The combustion of the sample releases heat, which is transferred to the surrounding water through the walls of the oxygen bomb, thereby increasing the temperature of the water. By accurately measuring the change in water temperature and combining it with the known volume and specific heat capacity of the water, the instrument can calculate the calorific value of the sample. In addition, the instrument is equipped with a thermostatic water circulation system and multi-probe temperature sensing technology to ensure temperature stability and measurement accuracy.
