When the development of photovoltaic industry, especially crystalline silicon solar energy, suffers from overcapacity, high energy consumption and high pollution, the solar thermal power generation technology is receiving attention. The National Development and Reform Commission will start the solar thermal power generation concession tender within this year, and is seen by the industry. As the beginning of the industrialization of solar thermal power generation, this can not help but let the solar companies in the crystalline silicon line slap their sweat: Is the rise of solar thermal power generation technology announcing that already controversial crystalline silicon solar energy has come to the end?
It is undeniable that the situation in which photovoltaic industry occupies the entire solar power industry will be broken by the entrance of light and heat. Photothermal power avoids the use of polysilicon, thus avoiding the high reputation of high pollution and high energy consumption, and also makes the cost of power generation from the international polysilicon price fluctuations. At present, some scientific research institutes and enterprises in China have gradually mastered the core technologies of CSP, which lays a solid foundation for the development of light and heat in China. In the view of analysts in the area of ​​new energy investment, the upcoming bidding for the Inner Mongolia Guangguang project may become a spark that sparks the passion for light and heat investment.
It is precisely because of the significant advantages of solar thermal power generation, according to media reports, at the project meeting of the New Energy Industry Research Group project of the 12th Five-Year Strategic Emerging Industry Development Consultation Research Project conducted earlier this year by the Chinese Academy of Engineering. As a key point, CSP is required to state in detail. An expert from the committee said that from September last year to the beginning of this year, the CSP project that completed the project proposal has increased by 3 GW. Since last year, major power giants have lapped a large area of ​​open space in the western flat area, waiting for follow-up development.
Does this mean that the PV line will be replaced? Industry experts said that in the context of increasing solar power generation in China and even in the world, these two technology routes have markets and are indispensable.
The main problem that CSPs currently face is that their costs must be reduced rapidly by means of economies of scale. It is estimated that a 1GW CSP power generation costs 0.7-0.8 yuan/kWh. Its investment is also more attractive than photovoltaic power plants. The use of domestic equipment to build a 50-megawatt trough-type solar thermal power station, including land costs, investment in equipment for concentrating arrays is expected to be around 1 billion yuan, and investment in unit equipment will be around 15,000 yuan/KW. In comparison, photovoltaic power plants of the same size require more than 2 billion yuan and 40,000 yuan/KW. However, at present, there are no large-scale solar thermal power station plans in China. As of 2009, the global solar thermal power installation is only about 700 MW.
This scale effect determines that CSP will be mainly used for the construction of large-scale power stations. Its energy storage and similar thermal power generation principles make the grid more able to accept its electricity. The scale of photovoltaic power generation is relatively small, and it can be applied to small-scale power plants and distributed power. For example, where large-scale solar power plants can be built without large amounts of open space, it is attached to photovoltaic systems that are off-grid or grid-connected.
At the same time, Arnang Solar Energy, which owns photovoltaic technology and solar thermal technology, believes that these two technological routes have their own advantages, and they can choose the most appropriate technology according to their specific circumstances.
Cutter Ladder
For easy removal of the Cutter Head, the ladder front piece is fitted with an eye to lock the cutter and unscrew it by reversing the hydraulic motor. In case this does not suffice, the assembly also has a `flame cut ring. After cutting away this ring, the cutter head will be loosened on the thread of the shaft.The box-type design is best suited for mounting a submersible dredge pump. This is a stronger design for heavy duty and longer wear life, because the box-type makes the whole cutter ladder heavier than the pipe-type. The use of a submersible pump allows for a larger dredged density at depth.

The cutter ladder front parts are of a pipe or a box-type rigid design, complete with the cutter drive motor, cutter shaft, cutter shaft bearing and side wire swivel blocks. The unit can simply be mounted to the ladder of the dredge, connect hydraulics, greasing and flushing water and is then ready for use. The unit's extra sturdy design ensures a long lifetime.
Cutter ladder is a Cutter Suction Dredger component. The cutter ladder front part is fitted with a cone in order to get an optimal flow of solids into the Suction Mouth. The suction mouth is also designed for this purpose. The high-efficiency slow running hydraulic motor drives the cutter shaft and cutter directly. The high starting torque of the motor helps to prevent the cutter from getting stuck.
