| Abstract: | The thermal degradation experiments were carried out for some combustibles such as plastic, hardboard, cloth, board, and thipywood which are common in buildings. The weight loss curves were obtained, and the kinetic parameters of activation energy E and frequency factor A were derived. Based on the thermal degradation kinetic equations and the characteristic concentration, the flashover forecast model for limited space was set up. Finally, a case was presented by this model. |
