Abstract
This paper provides an experimental investigation of a kerosene/air burner (the NexGen burner designed on the FAA's proposed ISO 2685 standard), which is used to generate flame/burnt gases impinging on material samples in the field of fire safety. The purpose of this study is to characterize this burner, and experimental means are implemented to better understand the effects of the equivalence ratio on the spatial distribution of the gas temperature (thermocouples), the heat flux (heat flux gauge), and gas emission species. Hence, the measured flame temperature, heat flux, and heat release rate increase up to a critical value of equivalence ratio equal to 1.03. Furthermore, a pyrolysis test was carried out on composite materials and the results of the comparative analysis of carbon-phenolic, carbon-BMI, and carbon-PEKK materials show that carbon-PEKK had the lowest mass loss, highest back-face temperature without significant material delamination, and the lowest concentration of gas emission species.
期刊介绍：
Fire and Materials is an international journal for scientific and technological communications directed at the fire properties of materials and the products into which they are made. This covers all aspects of the polymer field and the end uses where polymers find application; the important developments in the fields of natural products - wood and cellulosics; non-polymeric materials - metals and ceramics; as well as the chemistry and industrial applications of fire retardant chemicals.
Contributions will be particularly welcomed on heat release; properties of combustion products - smoke opacity, toxicity and corrosivity; modelling and testing.
