The ocean will be more lively and exciting with you. Welcome everyone to participate in more forum exchanges and discussions. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * At present, a number of wind, solar and thermal multi-energy complementary projects in my country are being planned to be developed, of which more than 20 projects are equipped with solar thermal power generation systems. Tower-type, trough-type or Fresnel-type CSP plants generally use molten salt for heat storage and exchange, and molten salt pumps are key equipment in CSP systems. Shouhang Hi-tech Dunhuang 100MW CSP Power Station is China’s first 100M level * * The solar thermal power generation demonstration power station is equipped with an 11-hour molten salt heat storage system and can continuously generate electricity for 24 hours. In March 2021, Dunhuang Shouhang Energy Saving New Energy Co., Ltd. commissioned Jinan Warwick to design and produce a high-temperature long-axis thermal salt pump. The pump has a design temperature of 595°C, a flow rate of 662m3/h, a lift of 41.8m, and a liquid depth of 18 meters. This pump is the first domestic long-axis thermal salt pump successfully applied in a 100MW solar thermal project. It has been running reliably for 9 months since December 6, 2021, marking the successful localization of the long-axis thermal salt pump. On December 6, 2021, the installation and commissioning of the above-mentioned long-axis hot salt pump was completed. Both parties conducted on-site acceptance of the pump. After acceptance, the pump was used as the main pump to participate in power generation. Acceptance result display: The pump has a wide stable operation range and can adapt to frequent startup conditions. In June 2022, the pump ran continuously for 262 hours, further verifying that Jinan Huawei hot salt pump can operate continuously and reliably for a long time.
Jinan Warwick, which has been focusing on the production of molten salt pumps for 17 years, has previously provided a long-axis temperature-regulating pump for the Hami tower-type 50MW solar thermal power generation project of CLP Engineering. It has been running reliably since the successful commissioning in December 2019.
In 2019, the long-axis molten salt pump of the Hami 50MW tower-type solar thermal power generation project of China Electric Engineering Co., Ltd. was* * One of the first batch of CSP demonstration projects and the first CSP project in Xinjiang Uygur Autonomous Region. This project is located in Naomaohu Town, Yiwu County, with a total investment of 1.6 billion yuan, covering an area of 440 hectares, and a planned project capacity of 2×50MW. In the first phase, a 1×50MW tower molten salt solar thermal power station will be constructed. The project is invested, operated and managed by China Energy Construction Group Investment Co., Ltd., and constructed by Northwest Electric Power Design Institute Co., Ltd. in a general contracting mode. Northwest Institute independently provides the entire plant and full-process engineering design. After the project is completed and put into operation, it will be able to supply 198.3 million kilowatt-hours of clean electricity annually and save 61,900 tons of standard coal every year. It will have a positive demonstration effect in promoting the development and progress of China's entire industrial chain of solar thermal power generation.
The temperature-regulating pump used in the Hami tower-type 50MW solar thermal power generation project of China Electric Engineering Co., Ltd. has a liquid depth of 17.35 meters, which is the longest molten salt pump in China. The pump adopts a VS1 structure and is designed, produced and manufactured in accordance with API610 standards. The long-axis molten salt pumps used in this project are provided by three manufacturers, two imported brands and one domestic brand. The domestic brand of long-axis molten salt pumps are jointly developed and provided by Jinan Warwick Pump Co., Ltd. and Beijing Electric Power Equipment General Co., Ltd. The same platform uses long-axis molten salt pumps from three manufacturers at the same time, and the success of domestic long-axis molten salt pumps is verified through comparative applications. This marks a further increase in the localization rate of key equipment for solar thermal power generation in my country, and the series of long-axis molten salt pump products has completely broken the monopoly of foreign products.
This marks a further increase in the localization rate of key equipment for solar thermal power generation in my country, and the series of long-axis molten salt pump products has completely broken the monopoly of foreign products. On August 29, 2018, the structural design, material selection, finite element simulation, thermal temperature field analysis, hydraulic model design and other work of the long-axis molten salt pump were completed, and production was subsequently arranged. On May 10, 2019, the long-axis molten salt pump was tested at the factory and the whole machine was trial-assembled. It was then dismantled and inspected, packed into boxes, and awaited shipment. On October 15, 2019, the long-axis molten salt pump was assembled at the Hami project site and is waiting to be hoisted into place. On October 23, 2019, the long-axis molten salt pump was hoisted into place and successfully installed on the 18-meter-high molten salt tank platform. At 23:39 on December 29, 2019, China Electric Engineering’s Hami 50MW tower solar thermal power generation project was successfully connected to the grid for the first time.
