Up to 850 DEG C to 1100 DEG C or so, dust content is high, and the conveying of this super high temperature flue gas is to the more demanding of pipeline, it is desirable that resistance to
High-temperature wearable, heat insulation effect will be got well, and pipeline external surface temperature control is at 50 DEG C or less.Traditional inside holding type high temperature boiler flue gas tube
Road, internal layer are heavy castable, then alumina silicate fibre blanket and rock wool are used to be kept the temperature, anchor studs material is welded on outer shield steel
Guan Shang, because of expansion, the welding of blind rivet and steel outer casing can crack, or even if blind rivet because being welded not open between steel outer casing
It splits, also results in blind rivet breathing, damage castable, castable cracking or part castable is made to fall off.Former inner wall is castable
High-temperature furnace smoke pipeline, castable is intolerant to abrasion, and long-term breathing, is easy to cause the cracking of inner wall castable and falls off, blind rivet
It is directly welded on steel outer casing, leads to heat bridge effect, the steel outer casing surface temperature made locally exceeds scope of design, leads to pipe
Road corresponding site appearance overtemperature.This structure existing defects, the safety that the entire high-temperature furnace smoke pipeline system made can not be long-term
Steady running.Since anchor studs thermal coefficient is big, so anchor studs root and the temperature of pipeline pad are excessively high, and anchor studs material
Expect that the thermal expansion amount difference with welding material causes the thermal stress of the two under high temperature excessive, damages fire resisting and thermal insulation material.Fire resisting
The wear-resisting property of liner is poor.The heat shaken stability of refractory lining is poor, therefore leads to the fire resisting and heat preservation of high-temperature furnace smoke pipeline liner
Material damage needs regular repairing, influences entire high-temperature furnace smoke pipeline system long-term safety steady running, and then needs to carry
The generation of problem above is prevented for a kind of structure.
Utility model content
The utility model is connected on to solve the anchor nail welding of the castable of thermal-insulating type high-temperature furnace smoke pipeline on steel outer casing
The thermal expansion amount difference of existing defects, anchor studs material and welding material causes the thermal stress of the two under high temperature excessive, in pipeline
Portion's refractory material and thermal insulation material fall off, and damage refractory material and thermal insulation material, and then provide a kind of applied to high temperature boiler flue gas tube
The composite block structure in road.
