The invention relates to a horizontal type
circulating fluidized bed boiler with a horizontal
cyclone separator, belonging to
combustion equipment of inferior fuels such as inferior
coal,
solid waste,
sludge or
biomass and the like, and the horizontal type
circulating fluidized bed boiler is particularly suitable for fluidized
combustion of a
biomass boiler with less ash content. The horizontal type
circulating fluidized bed boiler consists of a main
combustion chamber, a secondary
combustion chamber, a
burnout chamber and a
tail gas
flue, and a horizontal
cyclone separator is arranged in the
burnout chamber. The horizontal type circulating
fluidized bed boiler in the invention changes a single-stage vertical circulating structure of a vertical circulating
fluidized bed, can effectively reduce the height of a boiler and reduce the requirement for building height of a factory, meanwhile, the horizontal
cyclone separator is integrated in the
burnout chamber, the structure is more compact, thereby being beneficial to
miniaturization of a circulating
bed boiler and reducing the cost effectively. The horizontal type circulating
fluidized bed boiler has all the advantages of a circulating fluidized
bed and can combust fuels such as inferior
coal,
solid waste, municipal and industrial
sludge,
biomass and the like, has wide fuel adaptability and is high-efficiency combustion equipment with clean combustion, a compact structure and long service life.
