Utilizes a compressor refrigeration method to automatically adjust the temperature inside and outside the cylinder, reducing the cooling correction coefficient and making the measurement results more accurate. Employs an advanced refrigeration temperature control system to minimize temperature fluctuations during the experiment to zero. Ensures the stability and accuracy of experimental results. Features a semiconductor refrigeration-type water circulation system that determines the refrigeration capacity based on the previous calorific value, balances the water circulation system, maintains relatively constant water temperature, and reduces environmental impact

Experimental Steps:

1. First, weigh a certain amount of biomass pellets and place them in a drying oven for about 30 minutes (the drying time can be appropriately extended depending on the moisture content of the pellets);

2. Place the dried biomass pellets into a grinder and crush them until the particle size reaches about 0.2mm;

3. Weigh approximately 1g of the crushed sample and place it into a specialized calorimeter. Follow the calorimeter's operating steps to conduct the calorific value experiment;

4. After about 15 minutes, the calorimeter completes the experiment. The combustion value results are displayed on the computer screen or the calorimeter's display, and a printer automatically prints the results.
