Abstract
A circulating fluidized bed boiler superheater tube is composed of a high-temperature superheating piping (1), a suspended piping (2), a low-temperature superheating piping (3) and a stiffened plate (4); the superheater tube is characterized in that the stiffened plate is welded on the tube banks on both sides of the pipe bank centerlines (5) of the high-temperature superheating piping (1) and the low-temperature superheating piping (3), so that the flue gas resistance is closer to the design value to reduce partial abrasion and partial overheating of tube walls and avoid tube explosion; besides, the superheater tube is low in cost and easy to implement, which increases the service life of the superheating pipes and is especially applied to the tire industry.
Description
Technical field:
The utility model relates to a kind of boiler hot organ pipe, the hot organ pipe of particularly a kind of CFBB.
Background technology:
At present, YG-130/5.29-M
4High temperature superheater piping and low temperature superheater piping all are to be by the fixing high low temperature superheater tube of the boatswain chair on the column pipe superheater in the type CFBB superheating system, because column pipe middle part swing, distance between the overheated piping is inhomogeneous, out of plumb between the pipe row, the flow passage resistance that can cause boiler tail flue gas like this is excessive or too small, overheated piping serious wear, overheated piping long term wear can very fast attenuation, cause hot-spot, serious meeting causes the booster phenomenon, influences the service life of overheated piping.
Summary of the invention:
The purpose of this utility model is exactly will provide a kind of spacing between the overheated piping pipe row is consistent, and reduces pipe row wearing and tearing, hot-spot, avoids the booster phenomenon, and is cheap, implements the hot organ pipe of simple CFBB.
The purpose of this utility model is achieved in that the hot organ pipe of a kind of CFBB, by hyperthermia and superheating piping (1), hang outstanding piping (2), cryogenic overheating piping (3), gusset (4) and form, it is characterized in that described gusset (4) is welded on hyperthermia and superheating piping (1), cryogenic overheating piping (3) pipe row center line (5) the both sides pipe row.
The utility model compared with prior art has the following advantages:
Owing to adopted gusset (4) to be welded on hyperthermia and superheating piping (1), cryogenic overheating piping (3) pipe row center line (5) the both sides pipe row, thereby can make flue gas resistance more near design load, reduce tube wall concentrated wear and hot-spot, avoid the booster phenomenon, cheap, implementing simply increases the service life of superheater tube.

The specific embodiment:
Be welded on apart from pipe row center line both sides 1100mm pipe row place with 8800 * 60 * 4mm stainless steel gusset (4), during welded pipe row, guarantee that distance is 110mm between pipe row and the pipe row.
During use, the distance between pipe row and the pipe row is that 110mm immobilizes, and makes the boiler smoke resistance more near design load, can use.
Claims (1)
1, the hot organ pipe of a kind of CFBB, by hyperthermia and superheating piping (1), hang outstanding piping (2), cryogenic overheating piping (3), gusset (4) and form, it is characterized in that described gusset (4) is welded on hyperthermia and superheating piping (1), cryogenic overheating piping (3) pipe row center line (5) the both sides pipe row.
