Abstract

A gas turbine combustion chamber flame viewing device comprises a nut, sealing gaskets, an adapter, a cover plate, a floating lining, quartz glass, a backing plate, a combustion chamber casing and a flame tube; wherein the adapter is fixed on the combustion chamber casing, a hole on the adapter is directly aligned to an opening hole on the flame tube, the quartz glass and the sealing gaskets are fixed on the adapter by the nut, the adapter is extended form the combustion chamber casing to the backing plate fixed on the flame tube, a lower surface of the adapter protrudes outside of a lower surface of the cover plate, but does not stretch into the flame tube, the floating lining is movable, the seal can be formed through a matching surface between the adapter and the floating lining and a matching surface between the floating lining and the backing plate, and a gap between the cover plate and the floating lining is ensured. The gas turbine combustion chamber flame viewing device of the utility model has the advantages that: the gas turbine combustion chamber flame viewing device can be used for a test piece of an aeroengine or a ground gas turbine combustion chamber, and has a simple principle and a simple structure; in addition, the flame viewing device not only can realize viewing to the flame, but also can prevent extra air from flowing into the flame tube to adversely impact self performance the flame tube.

Description

A kind of gas-turbine combustion chamber flame finder
Technical field
The utility model relates to mechanical structure field, and a kind of gas-turbine combustion chamber flame finder is provided especially.
Background technology
As shown in Figure 1, in gas-turbine combustion chamber 1 and the test unit thereof,, observe the flame status in the burner inner liner in modern times through the air admission hole on the burner inner liner wall for the flame status of observing in the burner inner liner 2 often will be provided with the flame view window on casing 3 surfaces.But; Sometimes at a time when on the position burner inner liner of needs observation flame, do not have corresponding air admission hole; Will on the burner inner liner wall, increase by one like this and be specifically designed to the hole that flame is observed; Consequently increased partial admission's air mass flow of burner inner liner, and to performance deleterious impact such as its outlet temperature distributions.
Summary of the invention
The purpose of the utility model is in order to have realized the observation to flame; Unlikelyly again let extra air flow into burner inner liner and the performance of burner inner liner self is produced adverse influence; Casing and burner inner liner thermal expansion be inconsistent and on finder, produce stress when having prevented simultaneously firing chamber work again, and the spy provides a kind of gas-turbine combustion chamber flame finder.
The utility model provides a kind of gas-turbine combustion chamber flame finder, it is characterized in that: described gas-turbine combustion chamber flame finder comprises nut 6, sealing gasket 7, adapter 8; Cover plate 9, floating bush 10, quartz glass 11; Backing plate 12, combustion box 13, burner inner liner 14;
Wherein: adapter 8 is fixed on the combustion box 13; The perforate on the burner inner liner 14 is directly aimed in hole on the adapter 8; Nut 6 is fixed to quartz glass 11 and sealing gasket 7 on the adapter 8; Adapter 8 extends to backing plate 12 places that are fixed on the burner inner liner 14 by combustion box 13, the lower surface of the lower surface protrusion cover plate 9 of adapter 8, but do not stretch into i.e. 0 < L5 < L6 of burner inner liner; Floating bush 10 can move in certain limit L2, the inconsistent problem of axial thermal expansion amount between casing and the burner inner liner during with the work of compensation firing chamber.Form sealing through the mating surface between the mating surface between adapter 8 and the floating bush 10 and floating bush 10 and the backing plate 12, get in the burner inner liner to prevent two strands of extra air-flow air.For guaranteeing to have enough temperature compensation amounts, size L2 can be through calculating, and gap L 1 should be more than or equal to L2 with L3.For guaranteeing moving freely of floating bush 10, between cover plate 9 and floating bush 10, guarantee to have a gap, gap L 4>0.
Described 8 and floating bush 10 between little clearance fit, be used for the sealing.
The lower surface A of described adapter 8 does not protrude the inside surface B of burner inner liner 14.
On the described adapter 8 the transparent material materials and parts are installed.
The advantage of the utility model:
The described gas-turbine combustion chamber flame of the utility model finder; The testpieces that is used for aeromotor or ground gas turbine firing chamber or pneumatic plant; Theory structure is simple; Realized observation, unlikelyly again let extra air flow into burner inner liner and the performance of burner inner liner self is produced adverse influence that casing and burner inner liner thermal expansion are inconsistent and on finder, produce stress when having prevented simultaneously firing chamber work again to flame.
