Abstract

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.

Description

technical field [0001] The invention relates to a circulating fluidized bed combustion equipment, in particular to a horizontal circulating fluidized bed combustion equipment with a horizontal cyclone separator, which belongs to inferior coal, solid waste, urban and industrial sludge, biomass and other inferior Fuel combustion equipment, especially suitable for circulating fluidized combustion of biomass with low ash content. Background technique [0002] At present, the main combustion equipment for low-quality fuels such as low-quality coal, solid waste, sludge, and biomass in my country are chain furnaces, water-cooled vibrating grate boilers, and circulating fluidized bed boilers. Different types of furnaces are selected according to different fuels. Different furnace types have their own characteristics. [0003] Circulating fluidized bed boiler is an efficient and clean combustion technology developed in recent years. It has wide fuel adaptability and can burn high-qua...
