Description
Technical Field

[0002] With increasingly stringent environmental requirements for ships, waste heat turbine generator systems are being gradually installed. These systems generate steam by heating exhaust gases from the main engine to drive electricity generation. They work in conjunction with diesel generators and shaft-driven generators to supply power to the ship's main electrical grid, becoming a crucial component of the ship's propulsion system. To ensure the reliability of these systems, according to classification society rules, after installation, the turbine generators must undergo load tests: 4 hours of operation at 100% rated load and 0.5 hours of operation at 110% rated load. Simultaneously, the high cleanliness of the steam piping must be maintained to prevent damage to the turbine impeller.
[0003] However, due to limited mooring capacity at the docks during the mooring phase, the main engines often cannot reach the load required for testing. Therefore, turbine generator testing is currently mainly conducted during the sea trial phase. However, conducting turbine generator testing during the sea trial phase still presents several challenges. First, the grid compatibility of three generator sets with different characteristics was not verified beforehand, significantly increasing the risk of sea trials. Second, the additional load cylinders required during sea trials not only increase the testing period but also incur high costs. Finally, the scheduling of procedures during the sea trial phase is complex, the success rate is uncertain, and this seriously affects the ship delivery schedule. Summary of the Invention

[0025] Figure 1 This is a front view structural schematic diagram of a waste heat turbine generator mooring test system provided in an embodiment of this application; Figure 2 This is a top view of a waste heat turbine generator mooring test system provided in one embodiment of this application. Figures 1 to 2As shown, this embodiment provides a waste heat turbine generator mooring test system for conducting full-load and grid-connected tests on the waste heat turbine generator during the ship mooring phase. The system includes: a steam generation unit 100, a steam storage device 300, and a waste heat turbine generator. The steam generating unit 100 is installed on the dock 200 and configured to generate superheated steam. The steam storage device 300 is installed on the ship 400 and configured to store and stabilize the superheated steam generated by the steam generating unit 100, providing superheated steam for the waste heat turbine generator load test, the grid connection and coordination test of the waste heat turbine generator with other generator sets on the ship, and the steam pipeline purging test. The first air port of the steam storage device 300 is connected to the air outlet of the steam generating unit 100 through the first pipeline 500. The waste heat turbine generator is connected to the second air port of the steam storage device 300. The waste heat turbine generator is configured to receive the superheated steam output by the steam storage device 300 and conduct the waste heat turbine generator load test and the grid connection and coordination test of the waste heat turbine generator with other generator sets on the ship during the mooring phase based on the superheated steam.
[0026] This application provides a stable and controllable superheated steam source for turbine generator testing by coordinating an independently set steam generation unit on the dock with a steam storage device on board. This allows the load test and grid connection test of the waste heat turbine generator to be completed in advance during the ship's mooring phase, without relying on the main engine to generate waste heat steam. This overcomes the limitation of insufficient main engine load during the dock mooring phase, and can also reduce the number of test items and time occupied during the sea trial phase, reduce equipment operating costs, and shorten the construction cycle.
[0027] The vessel involved in this embodiment can be a passenger ro-ro ship. Accordingly, other generator sets on the vessel mentioned in this text generally refer to the main diesel generator set and the shaft-driven generator set of the passenger ro-ro ship. Furthermore, the main diesel generator set can serve as the core power supply unit during the ship's navigation and berthing operations, while the shaft-driven generator set generates electricity using the main engine shaft power. Here, the waste heat turbine generator, as an energy-saving power generation unit, needs to undergo grid-connected coordination tests with the main diesel generator set and the shaft-driven generator set to verify the compatibility of the three in terms of voltage, frequency, phase, and load distribution.
[0028] In this embodiment, passenger roll-on / roll-off ships generally have high requirements for the reliability of the power system and the stability of the power grid. The waste heat turbine generator mooring test system provided in this embodiment allows for the completion of load tests and grid-connected coordination tests of the waste heat turbine generator during the dock mooring phase. Furthermore, the grid-connected coordination test requires attention to the paralleling, disconnection, and load transfer capabilities between the waste heat turbine generator and the main diesel generator set, as well as the coordinated stability of the waste heat turbine generator and the shaft-driven generator set at different main engine speeds.
[0029] In one embodiment, the steam storage device 300 is provided with a third air port and a fourth air port. The third air port is connected to the outlet of the forward cofferdam steam drum 700 through a first purging passage, and the fourth air port is connected to the outlet of the aft cofferdam steam drum through a second purging passage. The second air port of the steam storage device 300 is connected to the waste heat turbine generator and the ship's outer hull discharge pipeline through a third purging passage. Here, the second air port is mainly connected to the inlet pipe of the disassembled waste heat turbine generator through the third purging passage. During operation, the steam storage device 300 outputs stable superheated steam, which is used to purge and clean the steam pipeline belonging to the forward cofferdam steam drum 700 through the first purging passage and the steam pipeline belonging to the aft cofferdam steam drum through the second purging passage. At the same time, the superheated steam can also purge the inlet pipe of the waste heat turbine generator through the third purging passage, discharging impurities in the pipeline through the outer hull discharge pipeline. In this embodiment, the first, second, and third purging passages are purged independently, which can more comprehensively maintain the cleanliness of the ship's steam pipeline, prevent impurities from entering the waste heat turbine generator and damaging the impeller, improve test safety and equipment operation reliability, and provide stable and reliable preconditions for the load test and grid-connected collaborative test of the waste heat turbine generator.
[0030] In one embodiment, purge detectors are installed at the outlet ends of the first, second, and third purge passages. These detectors are configured to detect the amount of residual impurities after pipeline purging, thereby verifying pipeline cleanliness. This embodiment, by installing purge detectors at the ends of the three purge passages, allows for early verification of the cleanliness of the entire steam pipeline during the mooring phase. This effectively prevents impurities such as welding slag and rust from entering the waste heat turbine generator and causing impeller damage, improving test safety and equipment operational reliability. Simultaneously, it reduces the risk of rework due to substandard pipeline cleanliness during sea trials, ensuring a smooth test process and successful delivery within the ship delivery cycle.
[0031] Furthermore, when the amount of residual impurities detected by the purge detector is below the preset threshold and there are no obvious hard particles, the cleanliness of the pipeline meets the safety operation requirements of the waste heat turbine generator. When the amount of residual impurities detected by the purge detector is above the preset threshold and there are obvious hard particles, the cleanliness of the pipeline does not meet the safety operation requirements of the waste heat turbine generator, and purging needs to continue until the amount of residual impurities detected by the purge detector is below the preset threshold and there are no obvious hard particles.
[0032] In one embodiment, the first pipeline 500 includes a first pipe segment, a second pipe segment, and a third pipe segment.
[0033] The first end of the first pipe section is connected to the outlet of the steam generating unit 100; the first end of the second pipe section is connected to the second end of the first pipe section; the first end of the third pipe section is connected to the second end of the second pipe section, and the second end of the third pipe section is connected to the first outlet of the steam storage device 300; the first pipe section and the third pipe section are configured as flexible pipe sections, and the second pipe section is configured as a rigid pipe section.
[0034] In this embodiment, the first and third pipe sections located at the equipment inlet and outlet are configured as flexible pipe sections. This can compensate for the relative displacement between the dock and the ship caused by tides, waves, or mooring conditions, preventing damage to the pipe interfaces due to shearing or pulling, and improving the sealing and reliability of the pipe connections. Furthermore, this embodiment configures the second pipe section located between the first and third pipe sections as a rigid pipe section to ensure stable and reliable support for the steam transport path, reduce pipe deformation and vibration, and improve the safety and stability during high-temperature and high-pressure steam transport.
[0035] The diameter of the first, second, and third pipe sections can be between 180mm and 220mm, which satisfies the steam flow requirements while also optimizing the pipeline layout space and facilitating installation.
[0036] In a preferred embodiment, the diameter of the first pipe section, the second pipe section and the third pipe section can be 200mm, which can be matched with standard interfaces to ensure sufficient steam flow area, which can meet the large flow and stable pressure steam supply required for high load test of waste heat turbine generator, and ensure stable and reliable test conditions.
[0037] In one embodiment, multiple Ω-shaped expansion joints are provided on the second pipe section. When the second pipe section is transporting a high-temperature medium, the Ω-shaped expansion joints are configured to extend when the temperature of the medium transported in the second pipe section is higher than a preset temperature, and to contract when the temperature of the medium transported in the second pipe section is lower than the preset temperature. This embodiment effectively absorbs the thermal expansion and contraction deformation caused by temperature changes during the transport of high-temperature steam in the second pipe section, reducing problems such as deformation, cracking, and loosening of joints due to thermal stress concentration in the pipeline. This ensures the structural strength and sealing reliability of the pipeline under high-temperature and variable-temperature conditions, making steam transport more stable and safe.
[0038] In one embodiment, the second section of the first pipeline 500 is made of seamless steel pipe, and the second section located on the boarding tower 600 is arranged at a height higher than the normal water level by a preset height. The connection between the first section of the first pipeline 500 and the outlet of the steam generating unit 100 is fixed by a fixing clip. The connection between the third section of the first pipeline 500 and the first outlet of the steam storage device 300 is also fixed by a fixing clip. In this embodiment, the second section is made of seamless steel pipe, which can withstand the long-term transportation of high-temperature and high-pressure superheated steam. Seamless steel pipe has high strength, good sealing performance, and is not easily deformed or leaked, which can ensure a stable and reliable steam supply. In addition, in this embodiment, the second section in the boarding tower 600 area is arranged higher than the normal water level, which can avoid the pipeline being soaked, corroded, or even damaged by tides and water accumulation, thereby improving the safety and service life of the waste heat turbine generator mooring test system in the dock mooring environment. At the same time, the fixing clips at the equipment inlet and outlet connections can limit the displacement of the pipeline ends, reduce the impact of vibration and tension on the interface, prevent flange loosening and steam leakage, and improve the reliability of the steam transmission pipeline connection.
[0039] In one embodiment, the steam generating unit 100 includes a boiler 110, an oil tank 120, and a water tank 130. The boiler 110 is mounted on a dock 200; the steam outlet of the boiler 110 is connected to a first steam outlet of the steam storage device 300; the boiler 110 is configured to generate superheated steam; the oil tank 120 is mounted on the dock 200; the oil tank 120 is connected to an oil supply pump of the boiler 110; the oil tank 120 is configured to provide fuel for the operation of the boiler 110; the water tank 130 is mounted on the dock 200; the water tank 130 is connected to a water supply pump of the boiler 110; the water tank 130 is configured to provide an initial water source for the boiler 110 and to recover condensate after testing.
[0040] In this embodiment, the boiler 110 is arranged on the dock 200, and an oil tank 120 and a water tank 130 are arranged next to the boiler 110 to facilitate the normal operation of the boiler 110. The oil tank 120 is mainly used to provide fuel for the boiler 110. The water tank 130 is mainly used to provide water for the boiler 110 and to recover condensate.
[0041] Furthermore, a steam outlet valve is provided at the steam outlet of the boiler 110 to control the opening and closing of the steam output path of the boiler 110 and to regulate the flow rate. By adjusting the steam outlet valve, it is easier to switch test conditions and adjust parameters.
[0042] Furthermore, the boiler 110 is also equipped with a safety valve. When the internal pressure of the boiler 110 exceeds a preset safety value, the safety valve can automatically open to release pressure, preventing the boiler 110 from operating under overpressure and ensuring safe use.
[0043] In one embodiment, an inlet shut-off valve is provided at the first air port of the steam storage device 300, and outlet shut-off check valves are provided at the second air port, the third air port and the fourth air port of the steam storage device 300.
[0044] Before starting the test, close all inlet shut-off valves and outlet shut-off check valves to ensure the waste heat turbine generator mooring test system is in standby mode. Start the steam generation unit 100. After the boiler 110 generates stable superheated steam, open the inlet shut-off valve. The superheated steam enters the steam storage device 300 through the first pipeline, where it is stored and pressure stabilized. At this time, the inlet shut-off valve can flexibly adjust the inlet flow rate according to the pressure inside the steam storage device 300 to ensure that the pressure inside the steam storage device 300 is maintained within the range required for the test. When the pressure inside the steam storage device 300 reaches the preset value, the outlet shut-off check valve at the corresponding outlet can be opened according to the test requirements. During pipeline purging tests, the outlet check valves at the third and fourth gas ports are opened. Steam flows through the first purging passage to the 700 outlet pipeline of the front cofferdam steam drum and through the second purging passage to the outlet pipeline of the rear cofferdam steam drum. Simultaneously, the outlet check valve at the second gas port is opened, and steam flows through the third purging passage to the inlet pipeline of the disassembled waste heat turbine generator, completing the synchronous or stepwise purging of the three pipelines. During load tests and grid-connected coordinated tests, the outlet check valves at the third and fourth gas ports are closed, and only the outlet check valve at the second gas port is opened to ensure a stable supply of steam to the waste heat turbine generator, providing continuous power for the tests. Finally, after the tests are completed, the inlet shut-off valve is closed first to cut off the steam supply, and then each outlet check valve is gradually closed. The system is shut down after cooling and depressurization.
[0045] In this embodiment, by setting an inlet shut-off valve, the opening and closing of the steam inlet passage and the regulation of the flow rate are realized, which can ensure the stable charging and pressure stabilization of the steam storage device 300 and avoid problems such as steam waste or pressure runaway. In addition, the outlet shut-off check valves set at each outlet can independently control the opening and closing of each gas path, realize flexible switching of different test conditions, and effectively prevent steam backflow, condensate backflow and other situations, avoid pressure fluctuations caused by cross-flow of gas between different gas paths, and prevent backflow steam from damaging the steam storage device 300 and pipelines.
[0046] In one embodiment, the steam generating unit 100 is configured with a design pressure of 4 bar to 12 bar, a design temperature of 125°C to 375°C, and a steam output of 4.5 T / h to 12.5 T / h; the steam storage device 300 is configured with a design pressure of 4 bar to 12 bar, a design temperature of 125°C to 375°C, and a volume ≥ 3.5 m³. Preferably, the steam generating unit 100 is configured with a design pressure of 8 bar, a design temperature of 250°C, and a steam output of 8.5 T / h; the steam storage device 300 is configured with a design pressure of 8 bar, a design temperature of 250°C, and a volume ≥ 3.5 m³.
[0047] This embodiment can stably output high-temperature, high-pressure superheated steam that meets the requirements of classification societies. It can guarantee the steam supply and pressure requirements of the waste heat turbine generator for 4 hours of operation at 100% rated load and 0.5 hours of operation at 110% rated load, and can also adapt to the flow rate and velocity required for pipeline purging. Furthermore, in this embodiment, the volume of the steam storage device 300 is set to be no less than 3.5 m³, which can effectively buffer steam pressure fluctuations and stabilize the output pressure, thereby ensuring the safe and reliable conduct of load tests, grid connection tests, and pipeline purging tests.
