METAGAZ (Metals - Gasification - Combustion)

At the time of the energy transition, the energy recovery of refuse derived fuel is an important path, which constitutes an ecological alternative to incineration. Flue-bed combustion is a possible way to control the maximum temperature of fumes and thus NOx emissions. Gasification, on the other hand, appears as an attractive process for future allowing the recovery of CSR from biomass or waste into a H2 and CO riched gas. The latter can itself be burned for energy purposes (heat, electricity) or processed to produce strategic gases such as methane or hydrogen. Globally, gasification or combustion processes face various technological and scientific challenges, one of the main being the limited lifetime of metallic materials used in various pipings and reactors. The gases produced can be particularly corrosive, particularly in the case of fuels rich in chlorine, sulphur, nitrogen, heavy metals, etc. The collaboration of the three partners of Carnot ICEEL aims to test different metallic materials, coated or not coated, and available on an industrial scale, under the representative conditions prevailing in combustion and gasification reactors in order to identify the influence of the material chemistry on the corrosion mechanisms and to evaluate their performance.
