Above-mentioned the present embodiment other structurally and functionally effect similar with previous embodiment 1-4, because of
This omission illustrates.
Therefore, the reaction-type steamturbine of the present invention, the steam transmitted from described boiler is respectively
While individual injection rotating part is sprayed by injection stream, its reaction force obtain propulsive force,
Even if containing condensed water in the steam of transmission in the most described boiler, also not due to described condensation
Water and cause the worry of the parts damages of steamturbine.Thus, described steaming not only it is greatly improved
The stability of steam turbine, and owing to there is no the damaged worry to described steamturbine, can profit
With the material of relative moderate, and packing engineering can be simplified, thus have and substantially reduce manufacturing expense
Effect.Such as, existing vane type turbine requires sophisticated design and makes the most hundreds of to several
The impeller of thousand, and owing to needing complicated assembling, it requires highly qualified professional and precision,
In contrast, the precision requirement that part design or the making of impeller etc. are assembled by the present invention is little very
Many, and high efficiency turbine can be obtained, therefore compared with present vane type turbine, can be with phase
When low price makes.
Additionally, the steamturbine of the present invention, it is arranged radially by multiple injection rotating parts
Reach stability, the most not only can reduce the size of whole steamturbine, and due to described steaming
Do not produce the flow resistance to steam between the injection rotating part of steam turbine, steamturbine can be greatly improved
Efficiency or the relative efficiency of boiler.This is when axially arranged described injection rotating part, described outside
Shell is formed the guide portion of inclination, the flow resistance of steam can be reduced, thus also can improve steamturbine
Efficiency and the relative efficiency of boiler.
Additionally, the steamturbine of the present invention, make use of newton third law of motion effect and anti-work
With, identical with the situation of vane type turbine (or momentum delivery type turbine), can reduce in order to
In turbine, produce the energy that propulsive force is consumed, thus high efficiency steamturbine can be obtained.
Additionally, the steamturbine of the present invention, it is assumed that certain from boiler steam pressure out, from
The vapor (steam) velocity of injection rotating part injection and the circumference produced by the rotation of described injection rotating part
When speed is identical, then steam is static relative to injection rotating part, i.e. has only to spray rotating part tool
There is the speed identical with the jet velocity of steam, and move to tangent line opposite direction, steam can be made
The whole momentum being had or the theoretical energy transmission efficiency of whole kinetic energy are 100%.Therefore,
The steamturbine of the present invention can obtain any the most inaccessiable height of vane type turbine
Efficiency.
Industry application possibility
The reaction turbine of the present invention, can be applied not only to steamturbine described above, and
And can be applicable to utilize the engine of gas turbine or compressed air etc. too.
