Abstract : The need to describe the complexity of the situation concerning fires with more accuracy and taking all the different phases of the fire behaviour (such as the ignition, its growing, its extinction ...) into consideration, has led to a great effort from the international research community in the past few years to improve the performance of the numerical simulation codes. These codes consist of different sub-models in order to simulate the different physical, thermal and chemical aspects of the fire, such as the thermal decomposition. This plays a significant role on the fire ignition and its evolution since it represents the fuel quantity supplied to the combustion process. Then, the requirement of a more detailed characterization and description is one actual and important challenge. This is the objective of this article which deals with pyrolysis of solid fuels in the conditions of fire, addressing both the experimental investigations and the modelling development aspects. After a presentation of the objectives and challenges of pyrolysis, this article details the different steps re- quired for its description, based on an experimental and numerical scaling-up approach. Examples of application are explained. Special focus is given on different scientific bolts, issues and challenges for pyrolysis modellin
