High-efficiency geothermal power generation system integrating integrated flow turbine and flash steam turbine

The present invention relates to a high-efficiency geothermal power generation system integrating a full-flow turbine and a flash-type steam turbine, and more particularly to a geothermal power generation technology capable of improving geothermal power generation efficiency by increasing thermal energy utilization.

According to geothermal power generation, it is particularly worthy of the attention of the government and manufacturers for the rich countries or regions. Because of the current technology, geothermal energy can be used for power generation, and its power generation efficiency is more economical than solar energy and offshore wind power generation. And the power supply is stable and can be regarded as the base load power. In particular, many areas of Taiwan contain abundant geothermal resources. If geothermal energy is used to generate electricity, it is possible to generate electricity with low total synthesis. If Taiwan can fully develop geothermal power, it can effectively solve the problem of insufficient power, and then replace nuclear or thermal power generation, reduce greenhouse gas emissions, and thus create opportunities for Taiwan to survive forever.

The geothermal working fluids in different locations are in an appropriate working pressure state. This appropriate working pressure is to make the geothermal fluid in a relatively stable fluid state. This means that when the local hot fluid comes to the surface, the outlet pressure in the tube flow is sufficient to provide stability to the working fluid. In general, this means that this pressure is sufficient for the geothermal fluid to rise smoothly from the ground to the ground, maintaining a state of saturated steam or supersaturated steam hot water two-phase flow. Geothermal fluids are generally "compressible fluids" on the surface and are in the form of wet vapors. Gushing out. Less than one-twentieth of the world's geothermal fields produce dry steam directly. Taiwan's Pacific Rim seismic belt, which is in the squeeze of plates, has abundant geothermal resources, but all of them are relatively low-temperature wet steam geothermal fluids below 200 ° C except for the Datun volcanic area. The percentage of steam in the working fluid. Below 20%. Therefore, how to effectively use the wet steam geothermal fluid to generate electricity has a crucial impact on Taiwan's future energy autonomy and green economy. Therefore, how to effectively develop and utilize the wet steam geothermal resources in Taiwan has become the future of green power. An important factor.

According to the current development of countries and regions in the world over the past two decades, the design of geothermal power plants is distinguished by the temperature of geothermal fluids. The power generation facilities designed according to the temperature and water vapor state of the geothermal heat source are generally dry steam. , flash steam and double cycle geothermal power generation technology.

The so-called dry steam generator set directs high-temperature dry steam (about 200 degrees Celsius or more) from the geothermal source "Production Well" to the steam turbine unit to drive the turbine unit to rotate and drive the generator. And generate electricity. Whether it is dry steam power generation, flash steam power generation, dual cycle power generation or other various types of fluid manifold circulation and other technologies, the working fluid is effectively activated through the pipeline, valve body and pump with electrical logic sequence control. The best way to deliver.

The so-called double-cycle power generation is a geothermal fluid (hot water or steam) obtained by using a geothermal "production well" as a heat source for heating a working fluid with a very low boiling point. Achieving a slightly high temperature (about 80 degrees Celsius to 150 degrees Celsius) of hot water is input to the heat exchanger to heat the working fluid, vaporizing the working fluid, and then directing the vaporized high pressure working fluid to the turbine or expansion screw via the pipeline. Drive the generator to generate electricity and push the turbine The working fluid after the machine or expansion screw is exothermic is recycled. Figure 6 is a schematic diagram of a set of dual cycle geothermal generator sets. The geothermal source production well provides an appropriate amount of geothermal fluid, and whether the geothermal fluid is geothermal water or water vapor, it will be introduced into a heat exchange evaporator (Evaporator) 90. Inside the evaporator 90, there is a working fluid that actually pushes the turbine to generate electricity. As mentioned earlier, this working fluid has a lower temperature boiling point, so when a geothermal fluid of about 80 to 150 degrees Celsius is introduced, the working fluid will change into a high pressure gaseous form in the evaporator 90. This high pressure gaseous working fluid will be directed to the turbine or expansion screw 91 to propel the main shaft of the gas vane or expansion screw and drive the generator 92. These gaseous working fluids are then recovered by a Condenser 93, causing the working fluid to phase again into a liquid state. Finally, this liquid working fluid is brought back to the evaporator 90 by the Fluid Circulation Pump 94 for re-cycling. This is the device of the Rankine cycle thermal power conversion. Usually, the working fluid is mostly organic matter such as R245fa. Therefore, the double cycle power generation system is mostly an organic Rankine cycle (ORC) geothermal power generation system.

The so-called flash steam power generation is to expand the hot water (about 150 degrees Celsius) obtained from the ground through a single or multiple stages to form a steam that still contains a certain amount of hot water, and then use the separator to heat the water. The steam is removed and removed, and the steam is directed via a line to a steam turbine generator to drive the steam turbine generator to operate to generate electricity. Figure 7 is a schematic diagram of a set of flash geothermal power generation systems. In this system, because the temperature of the geothermal fluid itself is high enough, in this system, it is not necessary to use another low-boiling working fluid, and the geothermal fluid can be directly used to drive the turbine to generate electricity. The geothermal fluid obtained from the geothermal source production well is a mixed-phase vapor fluid with a Celsius of more than 150 degrees Celsius. This kind of mixed-phase water-gas geothermal fluid power generation system, like the double-cycle geothermal power generation, is the same as entering the vapor-liquid separator. (Flash tank) 95. The only fluid in the vapor-liquid separator 95 is the miscible water vapor geothermal fluid. Because the vapor-liquid separator 95 has a large low-pressure space, the high-temperature and high-pressure mixed-phase water vapor geothermal fluid will rapidly expand and flash in this space, forming a separation of water and water vapor. Therefore, the vapor-liquid separator 95 is sometimes referred to in the literature as a separator, that is, a saturated or supersaturated water vapor is separated into hot water and high-pressure unsaturated water vapor. The separated unsaturated high pressure water vapor in the figure is the working fluid required for power generation in the system. Therefore, this high-pressure steam is introduced into the steam turbine 96 to drive the generator 97 to generate electricity. This water vapor is then condensed back into water using a condenser 98 at the rear end of the turbine 96.

When considering different geothermal fluids, the primary reference indicator is the temperature of the working fluid, while the secondary indicator is the pressure of the geothermal fluid. Since the main component of the geothermal fluid is water, if the reference geothermal water is derived from the temperature and pressure at the surface, the physical three-phase chart of the known water can be used to know the saturated partial pressure distribution of the water vapor. It can be seen that the working temperature of the geothermal fluid is one of the most important indicators; in addition, "dryness" refers to the percentage (in mass) of the vapor in the working fluid. Most of the geothermal fluids in Taiwan have a dryness below 20%.

Although the above-mentioned dry steam, flash steam and organic Rankine double cycle geothermal power generation systems can accept geothermal heat sources (such as hot water, steam or vapor-liquid two-phase working fluid) to drive turbines or expansion screws and generators. Electricity is generated. However, these conventional geothermal power systems are indeed incomplete, and there are still the following shortcomings:

1. Since the geothermal resources in Taiwan are mostly hot water-type wet steam geothermal fields of mixed fluids of hot water and steam, these geothermal power generation systems are indeed power generation designs that do not optimize the characteristics of Taiwan geothermal fields, although flashing The geothermal power generation system can flash some of the hot water into steam, but after all, the steam turbine is used to withstand the steam drive, while the unflashed hot water is discarded and not used, which will reduce the efficiency of geothermal power generation due to poor thermal efficiency. .

2. Since the geothermal power generation system only has a set of heat source nozzles, it is generally impossible to efficiently and uniformly eject the geothermal fluid into the blades of the turbine, thereby reducing the mechanical efficiency of the turbine and thereby affecting the performance of the geothermal power generation.

3. The geothermal power generation system cannot be applied to all available energy of the wet steam geothermal form of the geothermal fluid mixed with hot water and steam, so that the flash-type geothermal system only uses steam to propel the steam turbine and a large amount of unflashed hot water. Reinjection; as for the double cycle type, the heat exchanger is used and the expansion screw or gas turbine is used to withstand the driving of the gaseous working fluid to cause the generator to generate electricity, and the heat exchanger loses a lot of usable energy.

From the above-mentioned inductive analysis, it is known that these conventional geothermal power generation systems are indeed in need of improvement, and therefore, how to develop a set of hot water-type wet steam geothermal fields in Taiwan can be solved. The tailor-made geothermal power generation system has become a technical issue that Taiwan's related industries and academia are eager to solve and challenge.

Taiwan's current geothermal power generation capacity is zero. The development of geothermal power in the Yilan region has a major impact on Taiwan's future energy autonomy and green economy. In this way, the new technology will establish an exemplary full-flow geothermal power plant in Yilan to demonstrate the practicality of geothermal power generation in Taiwan, establish local talents for full-flow geothermal power generation, and simultaneously build local geothermal power generation.
