Pressure balance Lubricated Plug Valves are metal seated valves providing a tight shut off ( 0 leakage ) sealing, valves shall be regularly lubricated along with their operation by injection of suitable grease. Thanks to the absence of any body cavity and as well as a simple & tough design, they are highly recommended for any critical [Full ΔP" operation and for handling any media with an high % of solids contents, further more they provide an excellent resistance to abrasion, they are free from routine maintenance, providing a long service life.

Changzhou Longteng Thermal Technology Co., Ltd. (hereinafter referred to as Changzhou Longteng) Gansu Yumen 50MWe trough solar thermal power generation project feasibility study report review meeting was held in Yumen City, Gansu. The expert group led by Sun Rui, deputy dean of the General Electric Power Planning and Design Institute, conducted a two-day survey and evaluation of the project, and the project finally passed the review. The feasibility study of the project was prepared by Northwest Electric Power Design Institute Co., Ltd. The main units participating in this review meeting are Power Planning and Design Institute, Changzhou Longteng Thermal Technology Co., Ltd., Northwest Electric Power Design Institute Co., Ltd., Jiuquan Municipal Development and Reform Commission, and Energy Bureau. Yumen Municipal Government, Development and Reform Commission, Energy Bureau, etc.
The project is located in Yumen East Town, Gansu Province. It covers an area of ​​about 2.5 square kilometers and uses parabolic trough collector technology, including a set of 50MW solar thermal power air condensing steam unit with 9 hours molten salt heat storage system. In addition, one of the highlights of the project is the proposed use of a new generation of silicone oil as a heat transfer fluid rather than the biphenyl/diphenyl ether used in conventional trough power plants. The heat transfer medium is characterized by good safety and non-risk. Chemical products, high temperature performance, wide operating temperature range (-40 ° C - 425 ° C). The use of silicone oil medium will reduce the investment of heat storage system, and eliminate the need for anti-condensation measures of the collector field circulation system, improve turbine efficiency, reduce operation and maintenance costs, reduce the difficulty of system oiling and debugging, and ultimately reduce electricity cost and increase investment income.
The review meeting conducted in-depth and meticulous exchanges on the project's technical plan, land planning, and external conditions, which laid a solid foundation for the further advancement of the project.
CSPPLAZA reporter was informed that during the same period of the project review meeting, Changzhou Longteng Thermal Technology Co., Ltd. and Yumen Municipal People's Government signed a cooperation framework agreement for the 500,000 kilowatt CSP project. Both parties will rely on Yumen's high quality solar energy resources and good. The investment environment and the dominant position of Changzhou Longteng in the field of solar thermal power generation, the construction of a total of 500,000 kilowatts of solar thermal power generation projects in Yumen City. The 50,000 kW project of Longteng Yumen passed the feasibility study mentioned above is the first phase of the project.
