fluidized bed combustors for biomass boilers - asme

Fluidized Bed Combustors for Biomass Boilers - ASME

Fluidized-bed boilers are the most common type of boiler recommended for biomass fuel, which is burned within a hot bed of inert particles, typically sand. The fuel-particle mix is suspended by an upward flow of combustion air within the bed. As velocities increase the gas/solid mix exhibits fluid-like properties.

high-temperature corrosion problems in steam boilers

High-temperature corrosion problems in steam boilers

Abstract. There are essentially three distinct high temperature corrosion problems in fossil fuel fired steam boilers. These are: (1) corrosion of the superheaters and reheaters due to the deposition of fuel impurities, principally alkali metal sulfates in the case of coal-fired boilers and vanadium pentoxide in the case of oil-fired units.
