Abstract
Due to global warming, biomass fuels are gradually being used to replace fossil fuels. However, high-temperature biomass corrosion is a crucial issue affecting its future application. In this article, different factors affecting boiler performance are summarized from various studies to guide the optimization of boiler parameters in practical applications, such as corrosive components and boiler temperatures. Meanwhile, different coating formation methods and materials are summarized to provide better protection strategies. The potential coating materials for future research are also discussed. The addition of other elements, such as Ti, Mo, and W, has the potential to accelerate the formation of oxide layers during high-temperature corrosion and directly slow down the corrosion rate. Future studies should focus on these elements containing materials.
Highlights
With the development of human society, fossil fuels have gradually become the main source of energy
High-velocity oxygen fuel (HVOF) and high-velocity air fuel (HVAF) thermal spray are often used in the production of corrosion-resistant coatings
The HVOF and the HVAF are characterized by the high speed, which can accelerate to speeds of up to 300–500 m/s or higher
Summary
With the development of human society, fossil fuels have gradually become the main source of energy. The burning of fossil fuels results in a large amount of greenhouse gases, which gradually causes the greenhouse effect and endangers human survival. This urgently requires us to find another clean and pollution friendly way to obtain energy. The deposit causes serious corrosion to the pipe wall [1,13,14] These processes reduce boiler steam temperature and increase the risk of boiler shutdown [15]. A great deal of research has been devoted to the development of new materials and technologies to meet the high-temperature environment in the furnace While these technologies are gaining popularity, there are still many things we need to learn in order to achieve longer service times and better combustion performance. The corrosion resistance of each material is summarized, and the future development of materials is expected
