ABSTRACT: The combustion of MSW contains several species which if liberated into
the flue gas will participate in erosion-corrosion reactions with the alloy surface and
with the oxide layers. Actually with the evolution of material science and the discovery of 2D materials, we can handle that situation as well as possible.
The graphene as 2D material presents a lot of advantage due to it physical properties such: melting point,
boiling point and thermal conductivity, which can
help to manage the problem of low and middle temperature (100°C - 300°C)
erosion-corrosion into the boiler wall of waste to energy. The aim of the study
was focused on analyzing the resistance at low and middle temperature (100°C - 300°C) in the
enclosed environment and the corrosion-erosion resistance abilities of the graphene sheet as the 2D protective coating
material. This paper analyzed the possibility of using the graphene in
the aggressive environment which is waste to energy boiler. The results
obtained from this study after simulation using ANSYS software which is one of
the best software for simulations showed
that Graphene protects the furnace walls against corrosion-erosion for
temperatures lower than 400°C and that in the presence of certain impurities
such as: sodium (Na), sulfur (S), chloride (Cl) and Phos- phorous (P), Sodium
Chloride (NaCl), Hydrogen Chloride (HCl), Dioxide of Carbone (CO2)
and Dioxide of Sulfur (SO2).
