Application of High-Temperature Corrosion-Resistant Ceramics and Coatings under Aggressive Corrosion Environment in Waste-To-Energy Boilers

Nowadays, a promotion of high level recycling of waste and reduction of environmental load such as CO 2 and dioxins are required worldwide for waste treatment. The concepts of higher efficiency waste-to-energy (WTE) plants are positioned in the center of thermal recycling. A high total cost performance is required for those plants in the storm surrounding the society, such as the globalization of economy. The high-efficiency WTE boilers with steam conditions of more than 400 °C/3.9 MPa have been progressed recently. Also, the fluidized bed boilers burning industrial wastes such as many kinds of biomass fuels, RDF, RPF, etc., have been operated in 450 to 540 °C and 5.9 to 9.8 MPa.
