A Circilation Fluidized Bed Boiler for Overcome Combustion Failure in a Circulating Fluidized Bed Boiler Using Solid Fuel Containing Nonflammable and Chorine Component

摘要

The present invention relates to a circulating fluidized bed boiler capable of overcoming combustion failure in a circulating fluidized bed boiler using solid fuel containing incombustible and chlorine components and a method of operating the same. More particularly, it relates to various problems (combustion failure, efficiency reduction and temperature reduction, erosion and damage of equipment, stable combustion of solid refused fuel and bio-SRF, In order to prevent the operation member and the low efficiency and high temperature corrosion, the incombustibles are continuously removed from the lower part of the combustion furnace by using the inclined air dispersion plate, and the circulation particles accumulated on the inclined surface between the combustion furnace and the cyclone are prevented, And ensuring a sufficient combustion space in which a Char component with a long burning time can be sufficiently burned, thereby preventing the clinker (slag) of the fly ash containing chlorine component from being locally overheated, so as not to be immersed in steam and heat To a circulating fluidized bed boiler capable of reducing the high temperature corrosion of the tube.
