Definitions
- the invention relates to a gas turbine system with a Combustion chamber housing with massive inside Ceramic stones are lined with a with blades provided rotor and one with guide vanes Housing, in particular at least the first blades a ceramic thermal barrier coating on the turbine side wear.
- Such a gas turbine is for example from DE-OS 43 43 319 known.
- the combustion chamber housing, especially their Flame tubes in modern gas turbines can withstand extreme thermal loads executed.
- the interior walls can be covered with ceramic Insulation layers covered or with a sign massive ceramic stones.
- the blades of the turbine part of the gas turbine systems in particular the blades of the combustion chamber adjacent Steps often with ceramic thermal barrier layers as thermal protective layers provided, for example yttrium oxide stabilized zirconium oxide layers exist.
- the present invention is therefore based on the object in the case of a gas turbine of the type mentioned at the beginning meet the combustion chamber and the blades to protect thermal overload and on the other hand the service life to extend the turbine blades.
- the object is achieved in that the ceramic stones provided with a coating on its surface are.
- the ceramic stones have the advantage over heat shield plates made of other materials, for example super alloys, that higher material temperatures are possible and permissible. Only the stone fasteners need to be cooled. Because of the higher permissible material temperatures, this leads to the fact that incompletely burned flue gas particles that get onto the surface of the combustion chamber lining are completely burned there and less toxic CO (carbon monoxide) is produced in the exhaust gas, since this is converted into non-toxic CO 2 (carbon dioxide).
- the cooling air which is less required in comparison to metallic linings, is now additionally available for combustion. As a result, a lower flame temperature and noticeably fewer nitrogen oxides are formed, which, for known reasons, also pollute the environment.
- the ceramic stones according to the invention By coating the ceramic stones according to the invention is the detachment of such particles from the surface of the ceramic stones effectively prevented. Appears particularly cheap Here, the ceramic stones before installation in the combustion chamber housing to coat. The coating must be so be able to adhere well to the ceramic stones and good cohesion of the layer is guaranteed to to prevent flaking in the case of alternating thermal stresses. The coating of the ceramic stones thus forms one Layer to fix the surface particles.
- the coating of the ceramic stones thus forms one Layer to fix the surface particles.
- An embodiment of the invention provides that the coating consists of a metallic material and in particular is applied by means of vacuum plasma spraying (VPS).
- VPS vacuum plasma spraying
- Different corrosion protection layers that can be processed using VPS can be used for this purpose are used, e.g. B. the type M Cr AlY, where M is Ni or Co.
- a combination coating made of a metallic Bond coat as an adhesion promoter with an overlying ceramic cover layer would be applicable.
- the ceramic cover layer can be advantageous applied by air plasma spraying process his.
- VPS bondcoat can be dispensed with, is also the immediate coating of the stones with ceramic layers conceivable.
- the slight difference in the coefficient of thermal expansion between ceramic stones and a ceramic APS coating has a favorable effect on the resistance to alternating thermal stress.
- the execution of a ceramic layer as a thermal barrier layer has the additional advantage that the cooling air requirement of the combustion chamber lining is further reduced.
- Typical thermal insulation layers such as Yr 2 O 3 -stabilized ZrO 2 or SiO 2 or Al 2 O 3, are conceivable as ceramic coatings.
- the invention can also be advantageously configured by that the ceramic cover layer by means of air plasma spraying (APS) is applied.
- APS air plasma spraying
- the APS procedure provides a cheaper alternative the VPS method.
- the multilayer coating of the ceramic stones can also for thermal reasons or for reasons of better Cohesion of the layer can be advantageous.
- both the binding layer and the outer layer Coating can be carried out as a graded layer the thermal expansion behavior and chemical composition change constantly over the layer thickness.
- FIG. 1 schematically shows a gas turbine system according to the invention in a longitudinal section with a housing 1, in the fixed Guide blades 3, 4 are attached and a rotor 2, on the blades 5, 6 are attached.
- housing 7 is injected via the burners 14, 15 Fuel burned with the air from the compressor 16.
- the compressor 16 the input part of the Gas turbine plant referred to in the incoming air (Arrows 17, 18) compressed before flowing into the combustion chamber 7 becomes.
- a generator 20 is used to generate the connection shaft 19 electrical energy.
- FIG 2 is the surface area of the annular combustion chamber shown in simplified cross-section.
- the ceramic stones 10 consist for example of silicon or aluminum oxide.
- a coating of the ceramic stones 10 is shown enlarged in two layers, of which the lower layer forms a binding layer (bond coat) 12, the upper layer forms a ceramic layer 13 which adheres particularly well to the binding layer 12.
- the layers 12 and 13 together form a solid layer covering the ceramic stones 10, which binds any particles detached from the surface of the ceramic stones 10. Such particles can therefore have no erosive effect on the thermal barrier layer of the turbine blades of the housing or of the rotor.
- the adhesion-promoting layer 12 preferably consists of a metal-chromium-aluminum-yttrium alloy (MCrAlY), while the thermal insulation layer 13 preferably consists of yttrium oxide-stabilized zirconium oxide, SiO 2 or Al 2 O 3 .
- the coating is made of ceramic.
