Description
Technical field
The present invention relates to a kind of steam turbine equipment with high pressure turbine, middle-pressure turbine and low-pressure turbine.
Background technique
Current, as main electricity-generating method, use atomic power, firepower, these three kinds of methods of waterpower, from the viewpoint of stock number and energy density, envision above-mentioned from now on three kinds of electricity-generating methods and still can use as main electricity-generating method.Wherein, thermal power generation is as the high electricity-generating method of ability of safety and reply load change, and its value height is envisioned and still can be continued to play an important role at power field from now on.
The employed steam turbine equipment of coal combustion thermal power generation that comprises steam turbine has high pressure turbine, middle-pressure turbine, low-pressure turbine usually.In this steam turbine equipment, use the steam of 600 ℃ of temperature levels, the rotor of high pressure turbine or middle-pressure turbine, shell (casing) etc. are exposed to the part of high temperature, use the ferrite material that has heat resistance and manufacturing and Economy excellence with respect to the steam of 600 ℃ of temperature levels.
But, in recent years, in order to cut down CO
2The discharge amount and the further thermal efficiency that improves are just seeking to adopt the 650 ℃ of temperature levels or the technology of the steam condition of 700 ℃ of higher temperature levels.So, in patent documentation 1, disclose a kind of steam turbine equipment that can under the reheat steam condition is high temperature more than 650 ℃, turn round.
Figure 14 is the summary system diagram of disclosed existing steam turbine equipment in the expression patent documentation 1.Steam turbine power generating equipment 110 shown in Figure 14 is separated into first middle-pressure turbine 112 of High Temperature High Pressure side and second middle-pressure turbine 114 of low-temp low-pressure side with middle-pressure turbine, and the high pressure turbine 116 and second middle-pressure turbine 114 constituted one and form integrated device 122, on this basis, first middle-pressure turbine 112, low-pressure turbine 124 and the generator 126 of this integrated device 122 with the High Temperature High Pressure side is attached on the same axis in the lump.
The main steam that is superheated to 600 ℃ of temperature levels in boiler 132 is fed to high pressure turbine 116 by main steam pipe 134.The steam that is fed to high pressure turbine 116 is discharged from after expansion working, and gets back to boiler 132 by cold reheat pipe 138.The steam of getting back to this boiler 132 is heated once more in boiler 132 and becomes the steam of 700 ℃ of temperature levels, and is delivered to first middle-pressure turbine 112 by high temperature reheating pipe 140.The rotor of this first middle-pressure turbine 112 is made of the material (austenite heat-resistant steel) of high-temperature vapour that can anti-700 ℃ of temperature levels.Steam in first middle-pressure turbine 112 behind the expansion working is reduced to 550 ℃ of temperature levels and is discharged from, and splenium connecting tube 142 is delivered to second middle-pressure turbine 114 in the process.The steam that is transported to second middle-pressure turbine 114 is discharged from after expansion working, and is directed into low-pressure turbine 124 by cross pipe 144.The steam that is fed to low-pressure turbine 124 is discharged from after expansion working, and is transported to condenser 128.The steam that is transported to condenser 128 is condensed in condenser 128, and gets back in the boiler 132 after utilizing feed water pump 130 to boost.Generator 126 is driven in rotation according to the expansion working of each turbo machine and generates electricity.
In aforesaid steam turbine equipment, middle-pressure turbine is cut apart, and only first middle-pressure turbine 112 use can anti-steam more than 650 ℃ material, thereby, can adopt the steam condition more than 650 ℃, and, the use amount of the material that minimizing can anti-steam more than 650 ℃, thereby the manufacture cost of suppression equipment integral body.
But, in patent documentation 1 disclosed technology and since high pressure turbine do not use can anti-steam more than 650 ℃ material, therefore, when main steam uses steam more than 650 ℃, be difficult to reply.
And,, then be difficult to realize equipment shown in Figure 14 if consider jumbo steam turbine equipment.This be because, in order to constitute first middle-pressure turbine 112, use can anti-steam more than 650 ℃ for example Ni base alloy the time, make the viewpoint of limit from blank, be difficult to make 10t above turbine rotor and shell (casing), thereby can not make large-scale turbine rotor and shell.
Therefore, as shown in figure 15, also can consider first middle-pressure turbine 112 further is divided into 1-2 middle-pressure turbine 113, but can produce following problem in this case, promptly because of the increase of casing quantity, follow the building in this, the increase of pipe arrangement to cause the manufacture cost of equipment to increase.And, also produce following problem, promptly, number of axle amount (quantity of divided turbo machine) cause vibrative possibility to increase because of increasing.
In addition, also can consider not use Ni base alloy and adopt the ferrite material to deal with, but in this case, need in casing, import a large amount of cooled vapor, cause the reduction of turbine interior efficient.
