It is used to detect the combustibility of wood. During the heating process of wood, the moisture, volatile organic matter and other combustibles in the wood will gradually evaporate, and the combustibility of the wood will be reflected by the thermogravimetric curve. When heating wood, since the shape of the wood may be irregular, it may cause uneven burning at the bottom of the wood during heating and combustion, affecting the accuracy of the test data.
