Abstract

The invention discloses a hood strengthening device of a circulating fluidized bed, and relates to the technical field of hood devices of circulating fluidized beds. The hood strengthening device comprises an operation furnace, a secondary air inlet, a feeding port, cooling pipes, an air distributing plate, hoods and a slagging port. The feeding port is formed in the left side of the operation furnace. The secondary air inlet is formed above the feeding port. The air distributing plate is arranged at the bottom of the operation furnace. The cooling pipes are arranged in the air distributing plate. The slagging port is formed in the middle of the air distributing plate and penetrates the bottom of the operation furnace. The air distribution plate is provided with the hoods. The huge input for the improvement of the fluidized bed and several months of construction are avoided, the work loadloads of dismounting castable and machining and installing novel hoods is are directly omitted, the field construction and improving flexibility is improved, equipment maintaining costs are reduced, and the fluidization quality of a boiler is greatly improved.

Description

technical field [0001] The invention relates to the technical field of a fluidized bed boiler air cap device, in particular to a circulating fluidized bed air cap reinforcing device. Background technique [0002] With the gradual depletion and deterioration of coal resources, many small and medium power station circulating fluidized bed boilers that burn coal, especially the circulating fluidized bed boilers used by some small and medium , that is, it is difficult to meet the needs of worse and worse fuels in terms of the wind speed of the fluidized wind passing through the hood, and it is directly faced with difficulties such as the particle size of the fuel is not easily reduced, and the specific gravity of single particles is large. The original hood wind speed design If it is too small, it will cause frequent coking of the boiler, blockage of the slag outlet, and even failure to maintain normal production. The wind distribution board is completely removed, and the arr...
