Fluidized Bed Boiler A Fluidized Bed Boiler is a type of boiler that uses a bed of solid particles, such as sand or ash, which are suspended and behave like a fluid when air or gas is passed through them. This fluidization process enhances heat transfer and allows for efficient combustion of various fuels, including coal, biomass, and waste materials. The boiler operates at lower temperatures compared to conventional boilers, reducing the formation of harmful nitrogen oxides (NOx) and enabling b
