2D Materials As Protective Coating Against Low And Middle Temperature Erosion-corrosion In Waste To Energy Plant

The actual population increases and will increase more and more for next decade.We should know the increase of population is proportional with the increase of waste.A lot of countries around do not manage well their waste,most of them manage it by using the landfill however for example in 2016 the global waste contribute for 5%of global emissions,with an output of 1.6 billion metric tons of carbon-dioxide-equivalent.That number is expected to grow to 2.6 billion metric tons by 2050,which food waste accounted for 47%of those emissions.Regarding to this we need a good way to handle our waste.For that right,solution is to use waste to energy facilities but this one suffer a lot about the high temperature erosion-corrosion due to heterogeneity of the MSW.The combustion of MSW contains several species which if liberated into the flue gas can participate in erosion-corrosion reactions with the alloy surface and with the oxide layers.Other than the significant concentration of chlorine,there is a large concentration of ash,which can contain alkali metals such as sodium and potassium or heavy metals,such as zinc and lead.This is what we had analyzed below.All of that contribute to diminish the live of waste to energy power plant.Actually with the evolution of science and the discovery of 2D material,we can handle that situation as well as possible.The next page showed the advantage of graphene as 2D material what can help to manage the problem of low and middle temperature erosion-corrosion into the boiler of waste to energy.
