Technical field
The present invention relates to boiler washing pipe technical fields, and in particular to 660MW supercritical pressure turbine debugging apparatus.
Background technology
After boiler long-time service, can be deposited on the inner wall of boiler substantial amounts of steam dirt, iron filings and with the sundries such as iron rust,
When the sundries in boiler runs up to a certain amount of, it may appear that a part of sundries comes off, and when the sundries to come off is larger, is just present with
Sundries blocks steam conveying pipeline and pipe is caused to overheat explosion or sundries occur and is impinged upon with high speed steam flow on turbine blade
Leaf destruction is caused, has caused a serious accident.The most susceptible to plugging steam conveying pipeline of sundries come out from boiler is just proximate to pot
One section of nearest steam conveying pipeline of stove, as long as often clear to carrying out sundries close to one section of nearest steam conveying pipeline of boiler
It removes, the steam conveying pipeline that will make steam turbine is unimpeded.
When being now to carrying out eliminating impurities close to one section of nearer steam conveying pipeline of boiler, it is necessary to stop steam conveying
Pipeline is to steam turbine steam supply, so as to cause halt turbines.
The content of the invention
When the present invention is to solve now to carrying out eliminating impurities close to one section of nearer steam conveying pipeline of boiler, need
Stop steam conveying pipeline to that could be carried out after steam turbine steam supply, so as to cause the deficiency of halt turbines, provide one kind not
The steam supply of steam turbine can be achieved with steam conveying pipeline is stopped to being carried out close to one section of nearer steam conveying pipeline of boiler
Eliminating impurities can separate the inclusion particles in steam with steam, safe, the 660MW supercritical pressure turbines of good reliability
Debugging apparatus.
More than technical problem is solved by following technical proposal：
660MW supercritical pressure turbine debugging apparatus, the steam power transport system including steam turbine, steam power delivery system
System includes boiler, steam lead, is responsible for, goes out steam pipe, side pipe, scale removing tube and dirt removal device；The left nozzle of supervisor includes
The upper left nozzle and lower-left nozzle of forked arrangement, the right nozzle of supervisor are included in the upper right nozzle of forked arrangement and bottom right pipe
Mouthful；Downwardly toward the right side in the left bending segment pipe of side pipe is obtained after arc-shaped bending, the right end of side pipe is in the left end of side pipe downwardly toward a left side
