Abstract
The present invention seals the steam turbine room in the power generation cycle, the magnetic shaft is connected to the turbine inside the steam turbine room, and the magnetic shaft is connected to the turbine by the magnetic force installed in the shaft connected to the external generator to the turbine shaft is connected to the steam turbine It prevents the steam from penetrating through the chamber to prevent the steam from leaking out and prevents mechanical sealing of the shaft caused by the external drawing of the shaft, thus improving the power generation efficiency. It is about.
In the power generation system using a steam turbine, until now, the generator cannot be installed in the space inside the turbine chamber where the turbine exists. Therefore, the turbine shaft is taken out from the turbine chamber and the generator is connected to the shaft. . However, in order to generate power from the generator, it is very difficult to rotate the turbine shaft drawn out from the turbine chamber at high speed while maintaining the airtight inside the turbine chamber.
In the present invention, the turbine is installed in the turbine chamber by rotating the turbine, the magnetic body is installed in the shaft, and the turbine chamber is closed by the turbine chamber wall by installing a shaft in which the magnetic material is installed so as to transfer the force connected to the magnetic material of the shaft and magnetic force outside the turbine chamber. The two separate shafts were developed in such a way that they would transmit power to each other by magnetic force.
The method according to the present invention has no problem in turbine shaft rotation because the turbine shaft is not pulled out through the turbine chamber and prevents the steam that rotates the turbine from leaking to the outside, thereby realizing a good power generation system. . Especially, it is very useful for power generation system using low temperature boiling refrigerant using low temperature difference.
Description
Generator system design field
In a power generation system using a steam turbine, the turbine and generator are in separate spaces. In other words, the turbine exists in the turbine chamber, and the steam is generated from the boiler as the turbine rotates and enters the condenser. Generators connected to the shaft of the turbine exist outside the turbine chamber, so the turbine and generator are in separate spaces inside and outside relative to the wall of the turbine chamber. Therefore, the shaft connecting the existing turbine and the generator had to be connected through the wall of the turbine chamber. When shafts penetrate through the wall of the turbine chamber, the shaft must rotate at high speed and perform the two contradictory functions of not letting the steam inside the turbine chamber to the outside. As it is a precision machine that requires high reliability, it is expensive to implement. In particular, in the case of waste heat or solar power generation systems using low temperature boiling refrigerants utilizing low temperature differences, a small capacity generator is required.
The present invention seeks a method for transmitting the power of a turbine existing inside a turbine chamber to an external generator without the turbine shaft penetrating the turbine chamber. In other words, the turbine shaft and the generator shaft which exist in two independent spaces which are physically separated by the turbine chamber wall are devised to transfer the power to each other. Therefore, the turbine chamber is completely sealed so that the steam inside does not leak to the outside.
Magnetic material is installed on the turbine shaft inside the turbine chamber and magnetic material is installed on the generator shaft outside the turbine chamber to transfer the force.
Until now, in the power generation system using steam turbine, since the steam turbine and the generator exist in separate spaces, the turbine shaft is connected to the turbine shaft and the generator shaft to transfer power. As a result, the turbine shaft, which penetrates the wall of the turbine chamber, must perform two contradictory functions, which must conserve steam while rotating at high speed. In the method according to the present invention, the turbine shaft is not pulled out through the turbine chamber and is pulled out by the magnetic force transfer method between the turbine shaft and the generator shaft inside the turbine chamber, and there is no problem in the rotation of the turbine shaft and steam turning the turbine. Can be prevented from leaking to the outside, and a good power generation system can be realized. In particular, it is very useful for waste heat or solar power generation system using low temperature boiling refrigerant using low temperature difference.
