In recent years, the occurrence of various building fires has also put forward certain requirements for the fire safety performance of building materials. This is reflected not only in the requirements for the flame retardancy of building materials, but also in the requirements for the concentration of smoke produced and the heat release rate of building materials. In reality, the heat release rate of burning objects at the scene of a fire accident will affect the time it takes for combustible materials to ignite and burn, and the time it takes for them to flash over, thus affecting rescue time. The smoke produced by combustion is also one of the key factors in on-site rescue and life-threatening threats.

[0003] The existing single combustion test device needs to cool down to room temperature naturally after burning the material or directly carry out the combustion test of the next batch of materials. It cannot accurately control the initial temperature of the material before combustion according to various working conditions, thereby affecting the test accuracy of the material combustion. In addition, the ash of the burned material will accumulate inside the equipment, making it difficult for workers to clean it later. Therefore, a single combustion test device is proposed.
