Description
Technical field
This practical technique is to be related to gas-turbine combustion chamber transition section structure technical field, specifically a kind of new combustion
Room changeover portion.
Background technology
Combustion chamber changeover portion is gas turbine important component, the high-temperature high-pressure air flow generated from flame cylinder roasting,
It runs through changeover portion and sprays to rotating vane, drive rotor high-speed rotation, drive generating set work.Therefore, changeover portion is whole
The important component of platform generating set, front end are connect with burner inner liner, and rear end is connect by floating seal with first order jet nozzle, worked
Subject the multi-loads such as high temperature, vibration, abrasion, load-bearing in journey.Existing combustion chamber transition section structure is unreasonable, service life
Low, the problem of the erosion and wear being susceptible to, maintenance workload is big, and repair is also inconvenient.
Utility model content
The utility model technology provides a kind of safety and stability, simple and effective new combustion chamber aiming at the above problem
Changeover portion.
The utility model technology adopts the following technical scheme that：
A kind of new combustion chamber changeover portion, the preceding installation side of transition section cylinder are horn-like structures, after transition section cylinder
It is trapezium structure to install side；Preceding installation avris wall is equipped with preceding mounting groove, and rear avris wall of installing is equipped with rear mounting groove；After install
Wear-resistant of U-shaped is equipped in slot, rear mounting groove is interior to be equipped with floating seal by anchor ear.
The utility model advantageous effect is：Unit operation is more stable, and safety coefficient improves.Time between overhauls(TBO) increases length, uses
Service life doubles.Meanwhile also being brought to service work conveniently, wear-resistant of U-shaped is convenient for changing, and at low cost, work efficiency is high,
Economic benefit is improved to user.
