Description

Technical Field

[0001] This utility model relates to the field of power generation technology, specifically to a combined solar thermal steam cycle and gas turbine steam cycle power generation system. Background Technology

[0002] A gas-steam combined cycle (GSCB) unit introduces preheated natural gas into the combustion chamber of a gas turbine, where it mixes and burns with high-pressure air from a compressor. The resulting high-temperature, high-pressure gas flow drives the gas turbine to perform work. The exhaust gas from the turbine reaches temperatures as high as 600 degrees Celsius and still possesses significant energy. This high-temperature gas is then sent to a boiler to heat water into steam, which in turn drives a steam turbine to power a generator. GSCB units offer higher power generation efficiency than coal-fired units, require no desulfurization or denitrification, and have lower carbon dioxide emissions, resulting in less air pollution. However, natural gas faces resource scarcity, and relying solely on natural gas for power generation is insufficient to meet electricity demands.

[0003] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0038] In this embodiment, in order to heat the boiler 3, a heating oil pipe is spirally arranged on the outer periphery of the boiler 3. The heating oil pipe can also be directly installed inside the boiler 3. One end of the heating oil pipe is connected to the heat collection pipe 14 to input high-temperature heat transfer oil into the heating oil pipe.

[0040] In this embodiment, in order to recycle energy, the circulating water tank 5 has an inlet on the right side and an outlet on the left side that is connected to the boiler 3 to replenish water to the boiler 3. The circulating water tank 5 is equipped with a condenser pipe, a heat recovery pipe and a flue pipe. The inlet of the condenser pipe is located on the left side of the circulating water tank 5 and the outlet of the condenser pipe is located on the right side of the circulating water tank 5. The inlet of the condenser pipe is connected to the steam turbine 4 to condense and recover water vapor and preheat the water in the tank.

[0043] A power generation method for a combined solar thermal steam cycle and gas turbine steam cycle power generation system includes the following steps: (1) Heating flue pipes and heating oil pipes are spirally arranged around the outer periphery of boiler 3. High-temperature gas is input into the heating flue pipes through gas turbine 2 and high-temperature heat transfer oil is input into the heating oil pipes through solar collector 1 to heat boiler 3.

[0044] (2) The boiler 3 is divided into high pressure zone, medium pressure zone and low pressure zone. As the water flows from the low pressure zone to the high pressure zone, the high temperature gas and high temperature heat transfer oil flow from the high pressure zone to the low pressure zone. The high pressure zone can always maintain a high temperature to quickly generate steam. The generated steam flows through the steam box 7 to the steam turbine 4, which drives the steam turbine 4 to rotate, and then drives the generator 6 to generate electricity efficiently.

[0045] (3) The steam discharged from the steam turbine 4 flows to the circulating water tank 5. Since the water in the circulating water tank 5 flows from right to left, the steam flows from left to right in the circulating water tank 5, preheating the water in the circulating water tank 5 so that the water temperature on the left side of the circulating water tank 5 is always higher than the water temperature on the right side, thereby ensuring that the water flowing into the boiler 3 has a certain temperature to improve the heating efficiency.

[0046] (4) Similarly, the exhaust gas discharged from the heating pipe and the heat transfer oil discharged from the heating oil pipe flow from left to right in the circulating water tank 5 to preheat the water in the circulating water tank 5, so that the water temperature on the left side of the circulating water tank 5 is always higher than the water temperature on the right side, thereby ensuring that the water flowing into the boiler 3 has a certain temperature. At the same time, it can avoid the high temperature exhaust gas from being directly discharged into the atmosphere, causing pollution and the waste of heat energy of the heat transfer oil.

[0047] This utility model power generation system combines a dual energy system of solar energy and natural gas. On the one hand, it ensures basic power supply through natural gas, and on the basis of natural gas, it adds a clean energy - solar power generation system to improve power generation efficiency and effectively guarantee electricity demand.

[0048] This utility model's solar power generation system adopts an automatic sun-tracking structure, which can automatically adjust the angle of the trough-type concentrator according to the angle of sunlight. Moreover, compared with the traditional structure that requires one driver for each concentrator, this utility model only requires one driver to drive multiple concentrators to rotate and adjust their tilt angle, making the structure simpler and the cost lower.

[0049] This invention boasts high energy efficiency. Traditional power generation structures directly discharge high-temperature exhaust gas, which not only pollutes the environment but also wastes energy. This invention reuses the high-temperature exhaust gas from the gas turbine 2 to heat the boiler 3. After heating is completed, the exhaust gas with residual heat is reused a third time to preheat the water supplied to the boiler 3. In addition, this invention also reuses the steam discharged from the steam turbine 4 to preheat the water supplied to the boiler 3, effectively improving energy efficiency.

[0050] Specific implementation process:

[0051] Solar power generation system: The control mechanism is activated, which controls the drive to rotate the rotating frame. At the same time, the control mechanism controls the steering motor to work, which drives the drive gear 18 to rotate and move the steering rack 15, thereby driving the sector gear 16 to rotate. This controls the adjustment of the angle of the trough concentrator 13, ensuring that sunlight is concentrated on the collector tube 14 under the reflection of the trough concentrator 13, heating the heat transfer oil in the collector tube 14. The heated heat transfer oil flows to the boiler 3 through the heating oil pipe, heating the water in the boiler 3. The generated steam flows to the steam turbine 4 through the steam box 7, driving the steam turbine 4 to rotate and drive the generator 6 to generate electricity. The steam discharged from the steam turbine 4 flows to the circulating water tank 5 through the condenser pipe, preheating the water in the circulating water tank 5. The preheated water in the circulating water tank 5 continuously flows to the boiler 3 to replenish the water in the boiler 3.

[0052] Gas-fired power generation: The high-temperature flue gas generated by the combustion of natural gas drives the gas turbine 2 to rotate, which in turn drives the generator 6 to generate electricity. The high-temperature flue gas discharged from the gas turbine 2 flows to the boiler 3 through the heating flue pipe to heat the water in the boiler 3. The high-temperature flue gas discharged from the boiler 3 flows to the circulating water tank 5 through the exhaust pipe to preheat the water in the circulating water tank 5. The preheated water in the circulating water tank 5 continuously flows to the boiler 3 to replenish the water in the boiler 3.
