Definitions
- the present invention relates to a steam turbine and a steam turbine blade used in a power plant or the like.
- FIG. 2 shows a conceptual diagram of a power generation system using such a steam turbine.
- the steam generated in the boiler 1 is further heated by the heater 2 and guided to the steam turbine 3.
- the steam turbine 3 is configured by arranging a plurality of stages in the axial direction of the turbine rotor 4, each including a combination of a moving blade implanted in the circumferential direction of the turbine rotor 4 and a stationary blade supported by a casing. Then, the steam guided to the steam turbine 3 expands in the steam passage, whereby the high-temperature and high-pressure energy is converted to the turbine rotor 4 as rotational energy.
- Rotational energy of the turbine rotor 4 is transmitted to the generator 9 connected to the turbine rotor 4 and converted into electric energy.
- the steam that has lost its energy is discharged from the steam turbine 3 and led to the condenser 10 where it is cooled and condensed by the cooling medium 11 such as seawater to become condensed water.
- This condensed water is supplied again to the boiler 1 by the feed water pump 12.
- the steam turbine 3 is divided into a high-pressure turbine, an intermediate-pressure turbine, a low-pressure turbine, and the like depending on the temperature and pressure conditions of the supplied steam.
- a high-pressure turbine since the high pressure turbine and the intermediate pressure turbine are exposed to high-temperature steam, oxidation of the moving blades and stationary blade components of the steam turbine is remarkable.
- the surface roughness is minimized as much as possible by spraying fine particles on the surface when incorporating them as parts. This is because when the surface roughness of the parts is large, the flow of fluid is disturbed on the surface of the blades, etc., causing aerodynamic characteristics as the blades by causing separation, which causes the efficiency of the entire turbine to be reduced. is there.
- high-temperature members such as steam turbine blades are nickel-plated and then subjected to boriding by immersion to form a layer of iron boride and nickel boride on the blade surface.
- a method for improving the erosion property has been proposed (see, for example, Patent Document 2).
- the present invention has been made in response to such a conventional situation, and suppresses the change in the surface roughness of the steam turbine blades due to oxidation and the accompanying decrease in the aerodynamic characteristics of the steam turbine blades. It is an object of the present invention to provide a steam turbine and a steam turbine blade that can be maintained for a long time.
- the present inventors have conducted extensive research on the steam turbine blade structure for maintaining the turbine performance. As a result, for the steam turbine blades, by suppressing the change in surface roughness due to oxidation, the deterioration of the aerodynamic characteristics of the steam turbine blades is suppressed, and by maintaining the initial high aerodynamic characteristics, the turbine performance is maintained at a high level for a long time.
- the present invention has been completed.
- one aspect of the steam turbine of the present invention supports a turbine rotor, a moving blade implanted in the turbine rotor, a stationary blade disposed on the upstream side of the moving blade, and the stationary blade.
- One aspect of the steam turbine blade of the present invention supports a turbine rotor, a moving blade implanted in the turbine rotor, a stationary blade disposed on the upstream side of the moving blade, and the stationary blade. And a turbine casing containing the turbine rotor, the moving blade and the stationary blade, and a pair of the moving blade and the stationary blade forms one paragraph and a plurality of paragraphs in the axial direction of the turbine rotor
- a steam turbine blade used as the stationary blade or the moving blade in a steam turbine in which steam passages are formed side by side, and a surface treatment for suppressing an increase in surface roughness due to oxidation on at least a part of the surface It is characterized by that.
- FIG. 1 shows a configuration of a steam turbine and a steam turbine blade according to an embodiment of the present invention.
- the steam turbine 3 includes a turbine rotor 4, a moving blade 5 implanted in the turbine rotor 4, a stationary blade 6 disposed on the upstream side of the moving blade 5, and a stationary blade 6.
- a turbine casing 13 that supports and includes the turbine rotor 4, the moving blade 5, and the stationary blade 6 is provided.
- a pair of rotor blades 5 and stationary blades 6 forms one paragraph 7 and a plurality of paragraphs 7 are arranged in the axial direction of the turbine rotor 4 to form a steam passage 8.
- At least part of the surface of the stationary blade 6 and the surface of the moving blade 5 is subjected to a surface treatment for suppressing an increase in surface roughness due to oxidation. Thereby, the energy loss of the vapor
- the entire passage 8 including the stationary blade 6 and the moving blade 5, the end wall 14, and the platform 15 is collectively referred to as a steam turbine blade.
- the initial blade shape and surface roughness can be maintained for a long time. Therefore, the initial high level of the efficiency of the entire steam turbine 3 can be maintained for a long time.
- the above surface treatment can be performed on at least a part of the stationary blades 6 of the high pressure stage and the medium pressure stage.
- the stationary blade 6 is limited to the high-pressure stage and the intermediate-pressure stage in particular.
- the high-pressure stage and the intermediate-pressure stage are about 350 ° C. to 610 ° C. compared with the low pressure stage (350 ° C. to 20 ° C.). This is because the effect of the surface treatment is greater because the temperature is high and the oxidation easily proceeds.
- the surface treatment may be performed on at least a part of the moving blades 5 of the high pressure stage and the intermediate pressure stage.
- the rotor blades 5 are particularly limited to those of the high pressure stage and the medium pressure stage.
- the high pressure stage and the intermediate pressure stage are approximately 350 ° C. to 610 ° C. compared with the low pressure stage (350 ° C. to 20 ° C.). This is because the effect of the surface treatment is greater because the temperature is high and the oxidation easily proceeds.
- the stationary blade 6 and the moving blade 5 can be made of ferritic steel.
- ferritic steel is used for the stationary blade 6 and the moving blade 5 of the steam turbine 3 in view of the balance between material properties such as fatigue strength and creep resistance and cost.
- ferritic steel is defined as iron having a body-centered cubic structure. Even in the case where such ferritic steel is used, in the present embodiment, since the surface treatment is performed to suppress the increase in the surface roughness due to oxidation, the steam flow accompanying the increase in the surface roughness due to oxidation is reduced. Energy loss can be suppressed.
- ferritic steel is high chromium steel.
- the stationary blade 6 and the moving blade 5 can be made of a super heat resistant alloy. Recently, in order to improve turbine efficiency, the plant operating temperature has been increased, and as a material of the stationary blade 6 and the moving blade 5, a super heat-resistant alloy is sometimes used instead of conventional ferritic steel.
- the super heat-resistant alloy is defined as a cobalt-based or nickel-based material. Also in this case, since the surface treatment for suppressing the increase in surface roughness due to oxidation is performed, it is possible to suppress the energy loss of the vapor flow accompanying the increase in surface roughness due to oxidation.
- the surface treatment is preferably a surface treatment that does not increase the surface roughness of the base material of the stationary blade 6 and the moving blade 5.
- the main point of the present invention is not to increase the surface roughness. Therefore, even if the surface treatment for improving the oxidation resistance is performed, it is not preferable that the surface treatment increases the surface roughness of the stationary blade 6 and the moving blade 5.
- almost all surface treatment methods that are currently applied to or are being applied to steam turbine blades, such as thermal spraying increase the surface roughness and reduce the aerodynamic characteristics of the steam turbine blades. Resulting in.
- the surface treatment it is possible to employ a surface treatment including a step of applying a ceramic precursor to the surfaces of the stationary blade 6 and the moving blade 5 and a step of decomposing the ceramic precursor by heat treatment. it can.
- a surface treatment including a step of applying a ceramic precursor to the surfaces of the stationary blade 6 and the moving blade 5 and a step of decomposing the ceramic precursor by heat treatment. It can.
- this surface treatment since a ceramic thin film can be formed uniformly, the surface roughness change due to the surface treatment is extremely small. Therefore, the initial aerodynamic characteristics of the stationary blade 6 and the moving blade 5 are not deteriorated. Further, the ceramic film formed by thermally decomposing the applied precursor suppresses the oxidation of the stationary blade 6 and the moving blade 5, and it is possible to maintain the initial high blade aerodynamic performance over a long period of time. . Accordingly, it is possible to maintain a high level of the turbine performance of the plant over a long period of time.
- the surface roughness after the surface treatment preferably has a maximum height of 1.6 ⁇ m or less.
- Rmax is 1.6 ⁇ m or less, there is little turbulence in the steam flow, and the blade aerodynamic performance is not affected, but when the maximum surface roughness height is greater than 1.6 ⁇ m. This is because the steam flow is disturbed and the blade aerodynamic performance is degraded.
- the film formed by the surface treatment is preferably an oxide ceramic. This is because the oxide ceramics are excellent in oxidation resistance and corrosion resistance. This coating made of oxide ceramics can eliminate direct contact between the vapor and the metal substrate.
- the average thickness of the film formed by the above surface treatment is preferably 0.01 ⁇ m or more and 50 ⁇ m or less.
- the film thickness of the coating film is set to 0.01 ⁇ m or more and 50 ⁇ m or less for the following reason. That is, when the film thickness is thinner than 0.01 ⁇ m, the coating film cannot uniformly cover the substrate, the substrate is partially exposed, and the oxidation resistance of the substrate is drastically reduced. is there. On the other hand, when the film thickness is thicker than 50 ⁇ m, the adhesion strength of the coating film to the substrate is lowered, so that the coating film is cracked, the oxidation resistance of the substrate is lowered, and the coating film from the substrate This is because problems such as peeling occur.
- the film formed by the surface treatment is preferably at a position less than 10 mm and on the back side from the rear edge ends of the stationary blade 6 and the moving blade 5 toward the upstream side.
- the reason is that the position less than 10 mm from the trailing edge of the stationary blade 6 and the moving blade 5 toward the upstream side and the back side are important parts that determine the aerodynamic characteristics of the stationary blade 6 and the moving blade 5. This is because the surface roughness of the turbine greatly affects the turbine efficiency.
- a TiO 2 ceramic precursor was applied to the entire surface of the steam passage including the platform of the stationary vane 6 made of all high-chromium steel in the middle and high pressure stages of the steam turbine, and then heat treated at 400 ° C. for 10 minutes And the precursor was thermally decomposed to form a titanium oxide ceramic film.
- Rmax maximum height of the surface roughness
- the film thickness at this time was 0.8 ⁇ m.
- a film was formed by exactly the same method except that the film thickness was 0.008 ⁇ m, and evaluation was performed by the same method.
- Rmax maximum height of surface roughness
- a film was formed in exactly the same manner except that the film thickness was changed to 60 ⁇ m, and evaluation was performed in the same manner.
- Rmax the maximum height of the surface roughness
- the formation site (coating application site) of the coating film 17 by surface treatment is applied to all the moving blades and stationary blades of the high pressure stage and the intermediate pressure stage (the hatched lines in FIG.
- the evaluation was performed in the same manner, with the rear blade edge of the stationary blade 6 and the moving blade 5 being located at a position less than 10 mm and the back side from the rear edge of the stationary blade 6 to the upstream side.
- the coating application site was the entire stationary blade 6 and the moving blade 5
- the turbine efficiency was compared with the coating film formed on the entire surface, no difference was found between the two.
- the change in the surface roughness of the steam turbine blade due to oxidation and the accompanying decrease in the aerodynamic characteristics of the steam turbine blade are suppressed, and the initial high turbine efficiency level is maintained for a long time. can do.
- the steam turbine and steam turbine blades of the present invention can be used in the field of steam turbines for power generation in power plants. Therefore, it has industrial applicability.
