UA67480U - Unit for connection of a nozzle apparatus to combustion chamber of a gas turbine - Google Patents

Abstract

A unit for connection of a nozzle apparatus to combustion chamber of a gas turbine includes in peripheral zone an adapter element that connects the outer body of the nozzle apparatus to fire tube of the combustion chamber. The adapter element is arranged as a separate part that is profiled for provision of streamline flow of gas-air flow. Connection is carried out by surfaces in contact placed in arranged in normal directions planes and is arranged as a system of radial slots and lugs and stoppers placed on the adapter part and the outer body of the nozzle apparatus. The cowl has an outer cylindrical section with respective cylindrical section on the fire tube of the combustion chamber.

Description

parts (fairing) as part of the connecting unit; subjected to corresponding loads. For the radiator, the fairing is offset along the axis for clarity; combustion chamber pipes, they can be characterized

Fig. 2 - depicts a part of the assembly that contains a free, unrestricted temperature difference part of the heat pipe of the combustion chamber, which spreads in the axial direction and is limited in the radial direction. 1.

The connection of the nozzle device with the combustion chamber. For nozzle devices, the inherent temperature combustion includes the fairing 1, which is fixed in the external expansion in the radial and axial direction, the body 2 of the nozzle device, the system of radio and also the stresses from the swirling of the flow, which compe- grooves 3, 4 and protrusions 5, b, which are supported by the locking system. To ensure the fairing 1 and the outer casing 2 of the nozzle a-stability of the gas-air path geometry. the fishing apparatus is fixed between the external and internal

The fairing 1 is a rigid part that has several bodies. Diversification and difference has a configuration that ensures a smooth flow around the magnitude of temperature stresses that arise when the gas-air flow enters the blades 7 of the heat pipe of the combustion chamber and the nozzle of the apparatus-nozzle apparatus. those high-pressure turbines lead to increased

Centering of the heat pipe 8 of the combustion chamber wear of the contacting surfaces, which this technical solution is aimed at changing in relation to rigidly fixed parts of the nozzle. of the device is provided by the cylindrical Transitional element - the fairing 1 by the system 9 of the fairing 1 with the help of radial threads of radial grooves 3, 4 and radial projections 5, grooves 10 and fasteners 11. 6, as well as fasteners 11 located in the flanges

On the outer body 2 of the nozzle apparatus there are 12, which has freedom of movement in the radial flange 12, for placing the latches 11 in them, and a straight line independent of the outer body 2 of the nozzle projections 6, which enter the radial ring nut of the nozzle apparatus without losing docking with heat

From the fairing 1, which in total provide a free radial pipe 8. The system of grooves and protrusions increases the relative movement of the fairing 1 relative to the area of the contacting surfaces and the surfaces of the fixed node of the nozzle apparatus 13, thus having the ability to move relative to each other, compensating for the unevenness of the high of the same temperature, thus compensating for the sign change of the temperature voltages of the parts of the combustion chamber and the loads of the connected parts of the heat pipe and the nozzle apparatus. floating apparatus. Applying a useful model,

The operation of the combustion chamber and turbine unit is highly claimed, provides: the declared pressure consists in the following - the elimination of the need to perform a transition - principle aspects. of the element together with the nozzle device or with

The combustion chamber unit ensures uniform combustion in the chamber; combustion of a fuel-air mixture under high pressure - a moving connection, which during the operation of the product com. The formed gas-air flow enters the combustion chamber and reduces the effect of fretting, which provides a certain angle of rotation of the flow. wear of contacting surfaces, compensates for the impact

In connection with this, the main elements of the combustion chamber of the temperature loads of the constituent elements and the high-pressure turbine have a design that nodes; ensures the performance of this work, in the process of which - maintainability in case of wear and tear. 0909 I IZ
