Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] The embodiments of the present invention provide a coking treatment method for a fluidized combustion hot blast stove.

[0024] The coking of the hot blast stove has the following phenomena:

[0025] ⑴ When the fluidized bed is coking, the pressure in the air chamber fluctuates violently, and the pressure difference of the material layer drops significantly. When the coking is serious, the pressure in the air chamber drops suddenly.

[0026] (2) Observe that the bed material does not tumbling in the area where white sparks a...

Abstract

The invention discloses a fluidized combustion hot-blast stove coking treatment method. When the combustion temperature of a dense-phase zone is monitored and the temperature change speed is too high,the coal feeding amount should be reduced, and the air volume should be correspondingly increased; when the temperature rise can not be effectively controlled by the measures, a slag discharging pipeclose to a coal feeder side is immediately subjected to slag discharging, and slag discharging is stopped when the temperature has a decreasing trend; if the particle size is too large to boil, the cold slag discharge can be enhanced, and the air supply can be properly increased in a short time; when small coke blocks are coked in a stove, an operator needs to dredge a slag pipe in time, observesthe deslagging condition of the pipe is observed within a considerable period of time, and more slag is discharged than other deslagging pipes during deslagging until the small coke blocks are completely discharged; and if coking is serious, the stove is stopped, slag blocks in a hearth are cleaned away, cold slag is paved for re-ignition, and a cold state test is performed before ignition to check the air distribution uniformity of a hood. The treatment method is quick and appropriate, faults can be eliminated in time, the treatment time is greatly shortened, and the working efficiency of equipment is improved.

Description

technical field [0001] The invention relates to the technical field of high blast temperature, in particular to a coking treatment method of a fluidized combustion hot blast stove. Background technique [0002] Hot air stoves began to be widely used in my country in the late 1970s. The hot air generated by hot air stoves can be used to dry materials, heat and evaporate the moisture of dried materials to achieve the purpose of drying, and can also be used to heat greenhouses and farms, making greenhouses And the temperature of the livestock farm is suitable for the growth of animals and plants. In addition, as a heat exchange medium, hot blast stoves are also widely used for heating in various construction industries, indoor heating in winter, etc. [0003] Common causes of coking in hot blast stoves: [0004] ⑴The coal feeding system breaks down, and the coal feeding fluctuates too much. [0005] ⑵The particle size of coal exceeds the design requirements, causing the boili...
