A Circulating Fluidized Bed (CFB) is a type of combustion technology used primarily for burning solid fuels, such as coal or biomass. In a CFB, air is blown through a bed of solid particles, causing them to become suspended and behave like a fluid. This allows for efficient mixing and heat transfer, leading to improved combustion efficiency and reduced emissions. CFBs are commonly used in power plants and industrial processes due to their ability to handle a wide range of fuel types and their lower environmental impact. The design allows for better control of temperature and combustion conditions, making them suitable for various applications, including waste-to-energy conversion.
