Definitions
- the invention relates to a device for cooling a symmetrical, due to high temperatures over the circumference component of a turbine system subjected to unevenly heavy loads with the features of the preamble of claim 1.
- Such components are at different points in gas and steam turbine systems are provided.
- a special The application is the two-armed, with two inlet sockets Provided gas manifold, also called downpipe, the in Gas turbine plants between the combustion chamber housings and the The inlet nozzle of the turbine blades is arranged (DE-OS 198 15 473). Due to the special shape of the inlet nozzle this gas manifold are in its outlet cross section middle areas are much more thermally stressed than the upper and lower area.
- the outlet cross-section is cooled by cooling air is guided along the side facing away from the hot gas.
- This Cooling air is taken from the compressor of the gas turbine system.
- the Amount of cooling air limited by slots in the annular inner flange of the gas collecting tube are arranged, which is connected to the counter flange of the turbine. This Slots are even in the known gas turbine system distributed over the circumference of the inner flange. by virtue of the asymmetrical application of temperature by the of the hot gas flows coming in both combustion chambers in combination with the symmetrical cooling air distribution results in Circumferential direction on the inner flange of the gas manifold uneven material temperature.
- the invention has for its object the cooling of non-uniformly thermally stressed, generic components to equalize without additional effort.
- the intensity of convection cooling by the cooling air in the Exit cross section is determined by the speed and the amount of cooling air that flows along there. With that at all Cooling air flows, there is a pressure difference ⁇ p above that slotted annular inner flange required.
- the Cooling air flows through the circumference of the inner flange arranged slots.
- the ring-shaped inner flange of the component thus represents Throttle body for the amount of cooling air.
- Cooling air that normally cools areas that are low Temperature exposure have led to the areas that are exposed to higher temperatures.
- This increases the Material temperature of the outlet cross section in the cold Zones.
- the temperatures drop in the two hot ones Zones so that considered on the perimeter. an almost gives a uniform temperature profile.
- the resulting from the measures according to the invention are a reduction in local, life-limiting material temperature, in one Uniformization of the temperature distribution, in a reduction of temperature tensions, in an improvement in temperature and corrosion resistance and in an increase in Component life.
- Another advantage is that no increased Cooling air required. With the previously known and methods used to meet temperature peaks in Components that are subject to high temperatures are usually the additional cooling air is supplied to hot zones. This additional Cooling air is usually not available, however, or it leads to a reduction in the efficiency of the machine.
- the component shown as an example in the drawing is a Hot gas leading two-armed gas manifold 1, the inside a gas turbine plant between those not shown Combustion chamber housings and the inlet port of the not shown Turbine blades are arranged.
- the gas manifold 1 is with two inlet ports 2 for the hot gas from the combustion chambers Mistake.
- the inlet ports open into a gas collecting space 3 in lower part of the gas collecting tube 1.
- the gas manifold 1 is with an outer ring flange 4 and an inner ring flange 5 provided, which are connected to the counter flanges of the gas turbine become.
- the compressed hot gas flows out of the combustion chambers through the inlet nozzle 2 of the gas manifold 1 and is in the gas plenum 3 merged and collected before being in the gas turbine flows and the turbine rotor with the Rotating blades.
- the inlet nozzle 2 Due to the design of the inlet nozzle 2 is the Gas collecting chamber 3 of the two-armed gas collecting tube 1 through the introduced hot gas unevenly thermally loaded. There are the middle areas, the 3 o'clock and 9 o'clock positions correspond, more heavily burdened than the upper and the lower area of the gas collecting space 3 according to the 6 o'clock and the 12 o'clock position.
- the entire gas collecting tube 1 is outside by compressor air convectively cooled, the compressor of the gas turbine plant is removed.
- This cooling air is used on the Inner cone 6 of the gas collecting space 3 is guided along.
- To this Purpose are in the inner ring flange 5, which as a ring in the Flow path of the cooling air protrudes, slots 7 or others Openings attached.
- the cooling air flows through these slots 7 from.
- the driving force for the flow of cooling air is one Pressure difference, which is on both sides of the slotted inner ring flange 5 builds.
- the slots 7 are uneven in the inner ring flange 5 distributed over its circumference. As from Fig. 2 too can be seen, the distance of the slots 7 from each other in the Sections of the inner ring flange 5 largest, the most strongest thermally stressed areas of the gas collecting space 3 are neighboring. These are the areas that the 3 o'clock and the Correspond to 9 o'clock position. In those sections of the inner ring flange 5, which the least heavily loaded Regions of the gas collecting space 3 are adjacent, the distance the slots 7 from each other largest. Based on these Distribution of the slots 7, the cooling air flows along increasingly the most thermally stressed areas of the Gas collection room 3.
- the width of the slots 7 in the Ways can be varied so that the slots 7 over the circumference of the Ring flange 5 have a different width and that the width of the slots 7 in the sections of the ring flange 5th is larger, the more heavily used areas of the Gas collecting tube 1 are adjacent.
- the slots 7 of different widths evenly or as before for the slots 7 of equal width is explained, unevenly over the The circumference of the inner ring flange 5 can be distributed.
