And shake, these types of situation can make boiler internal structure and there is impaired risk with the relevant equipment of boiler, so to have
Relevant safeguard measure, using supercharged steam generator as the ship of active force equipment, when carrying out the transformation of the height speed of a ship or plane, supercharged steam generator
Combustion parameter changes greatly, and boiler plant is metal material, in boiler when burning Parameters variation, since the boiler that expands with heat and contract with cold is whole
The body shape changes that body and part have degree different, Turbo-charged Marine Boiler are belowdecks connected with other equipment in hull and cabin
It connects, the damage of itself and relevant device is easily caused when body shape changes occurs in supercharged steam generator.
Invention content：
To solve the above-mentioned problems, the present invention is directed to propose a kind of expansion buffer system suitable for Turbo-charged Marine Boiler.
The technical scheme is that：Suitable for the expansion buffer system of Turbo-charged Marine Boiler, including boiler, it is suitable for ship
It is grouped as by boiler exterior coupling part and internal connection with the expansion buffer system of supercharged steam generator, boiler exterior connection includes
Exhanst gas outlet expansion buffer device, air intlet expansion buffer device and boiler sliding support；Boiler internal connection includes boiler
Inside collection box part and boiler pipe part；
Wherein, in boiler internal collection box part, the horizontal direction and vertical direction of boiler internal header have boiler header
Longitudinal dilatation device and the connection of the shell of boiler header horizontal expansion device and boiler；
The pipeline of boiler pipe part is passing through part to be equipped with boiler pipe outlet expansion device with boiler shell, in boiler
Boiler pipe horizontal expansion device is serially connected among the boiler pipe in portion；
The smoke outlet of exhanst gas outlet expansion buffer device is sequentially connected the oblique section of boiler flue gas outlet expansion buffer device
With boiler flue gas outlet expansion buffer device straight section, ripple is serially connected in the pipeline of boiler flue gas outlet expansion buffer device straight section
Pipe.
The present invention has the advantages that：System is filled by the way that the exhanst gas outlet expansion buffer that boiler exterior connects is arranged
It sets, air intlet expansion buffer device and boiler sliding support；The collection box part of boiler internal and boiler pipe part, avoid
The supercharging unit of upper boiler is impacted by caused by boiler length travel, and boiler is supported on Ship Structure by sliding support
On, boiler sliding laterally on hull may be implemented, reduce the side knock between boiler and hull, installation boiler header is swollen
Swollen device can offset the length travel of header, and pipeline expansion device can reduce impact of the pipeline expansion to boiler jacket body, be
The buffering that uniting realizes between marine boiler and hull and relevant device connects, and buffering is since the boiler that expands with heat and contract with cold is whole and part is equal
There are the body shape changes that degree is different, reduces mutually to impact damaging between boiler and other equipment under extremity.

Specific implementation mode：
The invention will be further described below in conjunction with the accompanying drawings：
Shown in Fig. 1 combinations Fig. 2~Fig. 4, it is suitable for the expansion buffer system of Turbo-charged Marine Boiler, including boiler 1, is applicable in
It is grouped as by 1 external connection part of boiler and internal connection in the expansion buffer system of Turbo-charged Marine Boiler, is connected outside boiler 1
It connects including exhanst gas outlet expansion buffer device 2, air intlet expansion buffer device 3 and boiler sliding support 4；Connect inside boiler 1
It connects including boiler internal collection box part 7 and boiler pipe part 10；
Wherein, in boiler internal collection box part 7, the horizontal direction and vertical direction of boiler internal header have boiler header
Longitudinal dilatation device 8 and boiler header horizontal expansion device 9 are connect with the shell of boiler 1；
The pipeline of boiler pipe part 10 is passing through part to be equipped with boiler pipe outlet expansion device 11 with 1 shell of boiler,
It is serially connected with boiler pipe horizontal expansion device 12 among boiler pipe inside boiler 1, pipeline can be reduced and expanded outside to boiler
The impact of shell；
The smoke outlet of exhanst gas outlet expansion buffer device 2 is sequentially connected the oblique section of boiler flue gas outlet expansion buffer device
14 and boiler flue gas outlet expansion buffer device straight section 15, it concatenates in the pipeline of boiler flue gas outlet expansion buffer device straight section 15
There is bellows 13.
Exhanst gas outlet expansion buffer device 2, air intlet expansion buffer device 3 connect the supercharging of boiler 1 and 1 top of boiler
Unit 6, when 1 load of boiler increases, boiler 1 is moved up because of expansion, and exhanst gas outlet expansion buffer device 2 passes through bellows 13
Compress own dimensions；When 1 load reduction of boiler, 1 size of boiler is restored downwards, and bellows 13 stretches downwards, boiler flue gas outlet
The oblique section 14 of expansion buffer device and boiler flue gas outlet expansion buffer device straight section 15 can also be overcome by the Compression and Expansion of itself
Ship jolts caused length travel, and the supercharging unit 6 for avoiding 1 top of boiler is impacted by caused by 1 length travel of boiler.
Boiler 1 is supported on by boiler sliding support 4 in 5 structure of hull, and transverse direction of the boiler 1 on hull 5 may be implemented
Sliding, reduces the side knock between boiler 1 and hull 5.
Header in 1 shell of boiler is connected with pipe valve, and header, pipeline expansion or ship jolt and boiler caused to shake
When, header has horizontal or length travel, and boiler header horizontal expansion is installed in header horizontal direction and outer housing junction
Device 9 can offset its horizontal displacement.Boiler header longitudinal dilatation device 8 is installed at the pipeline of its connecting flange can offset header
Length travel.
System by be arranged boiler exterior connect exhanst gas outlet expansion buffer device, air intlet expansion buffer device and
Boiler sliding support；The collection box part of boiler internal and boiler pipe part avoid the supercharging unit of upper boiler by pot
Impact, boiler caused by stove length travel are supported on by sliding support in Ship Structure, and boiler may be implemented on hull
It slides laterally, reduces the side knock between boiler and hull, installation boiler header expansion device can offset longitudinal position of header
Move, pipeline expansion device can reduce pipeline and expand impact to boiler jacket body, system realize marine boiler and hull and
Buffering connection between relevant device, buffers due to the body shape changes that the boiler that expands with heat and contract with cold is whole and part has degree different, subtracts
Mutually impact damages between boiler and other equipment under few extremity.
