Boiler coking detector

Abstract

The invention discloses a boiler coking detector. The boiler coking detector comprises a protecting tube, a lens cone, a cooling tube and a connector, wherein the lens cone is arranged inside the protecting tube; the cooling tube is arranged between the lens cone and the protecting tube; a main lens hole and a secondary lens hole are formed in one end of the protecting tube; the connector is arranged at the other end of the protecting tube; lenses are respectively arranged at the main lens hole and the secondary lens hole. By adopting the mode, the boiler coking detector disclosed by the invention can effectively monitor the security of the interior of a kiln, a glass molten tin bath and a kiln lining, is simple, reliable and convenient to use, can observe in naked eyes by using an eyepiece directly, can also monitor by using cameras or digital single-lens reflex cameras which are connected through connecting rings, and is flexible in observation.

Description

technical field [0001] The invention relates to the field of kiln equipment, in particular to a boiler coking detector. Background technique [0002] The root cause of coking is that the ash in the molten state is deposited on the heating surface, which is related to the injection angle of the burner, combustion adjustment, and air leakage of the boiler equipment. Ash melting point is the key to coking. Coking will cause the temperature of superheated steam to rise, and cause the temperature of superheated steam and reheated steam to desuperheat water to increase, and even cause the steam-water pipe to burst; coking will reduce the output of the boiler, and in severe cases, it will be forced to stop; The service life of the equipment; the loss of exhaust smoke increases, the efficiency of the boiler decreases; the power consumption of the induced draft fan increases; because the coking is often uneven, the slagging of the water wall will affect the water circulation safety ...

AI Technical Summary

Problems solved by technology

Coking will cause the temperature of superheated steam to rise, and cause the temperature of superheated steam and reheated steam to desuperheat water to increase, and even cause the steam-water pipe to burst; coking will reduce the output of the boiler, and in severe cases, it will be forced to stop; The service life of the equipment; the loss of exhaust smoke increases, the efficiency of the boiler decreases; the power consumption of the induced draft fan increases; because the coking is often uneven, the slagging of the water wall will affect the water circulation safety of the natural circulation boiler and the water wall of the forced circulation boiler. Thermal deviations have adverse effects

[0003] Coking is easy to form ash and slag, which makes it difficult to transport the slag extractor and slag crusher, and sometimes overloads and trips. In severe cases, the slag ditch is blocked and the load has to be reduced.

[0004] If the coke is fused into a large piece, it will fall from the top due to gravity, causing the water wall of the cold ash hopper to be smashed

Low load will cause unstable combustion or even flameout due to loss of large pieces of coke
