Judging the quality of charcoal produced by the carbonization machine requires comprehensive consideration of appearance characteristics, physical properties, chemical properties, combustion performance and environmental protection indicators.
First, you can observe the appearance. High-quality charcoal usually presents a shiny black color. The surface of high-quality charcoal is relatively smooth, without obvious cracks, burrs or unevenness. In addition, the charcoal should have a relatively regular shape.
Secondly, the density of charcoal can be calculated by simple weighing and volume measurement methods. Generally speaking, the density of high-quality charcoal should be within a certain range. Too high or too low may cause problems. Then press it with your hands or tap it lightly with a tool to feel the hardness of the charcoal. Good quality charcoal should not be too hard. If it is too hard, it is not easy to ignite. You can also judge the size of the porosity by observing the cross-section of the charcoal or using a professional porosity measuring instrument.
Finally, the most important indicator for judging the quality of charcoal is the fixed carbon content, which can be determined by chemical methods. The lower the ash content, the higher the purity and quality of the charcoal. In addition, at a certain temperature, the substances that can volatilize from the charcoal are also one of the important means to judge the quality of charcoal.
High-quality charcoal should also minimize the content of harmful substances, such as sulfur, phosphorus, heavy metals, etc. These substances will release harmful gases during combustion, which will harm the environment and human health. The environmental performance of charcoal can be judged by observing the flue gas emissions during the combustion process.
Therefore, if you want high-quality charcoal, the choice of charcoal machine is crucial. If you have any equipment needs, please feel free to contact Zhengzhou Dingli New Energy Equipment Co., Ltd., and a professional team of engineers will give you a customized production line solution!
