China's First Steam Turbine Project for Inducing Draft Fans Officially Implemented

The first domestic project to utilize steam turbine-driven induced draft fans in large power plants has been implemented. Huaneng Power International Haimen Power Plant, the first power plant to eat crabs, signed contracts with Hangzhou Steam Turbine Co., Ltd. for four sets of 1000MW power plant driven draught turbine turbines. The first two manufacturing orders have been issued and the delivery date is August 7, 2010.
Induced draft fan is the earliest start-up equipment of any moving equipment in the power plant. Its reliability is higher than that of the feed-water pump turbine. If the turbine is used to drive, it will greatly increase the complexity of the power plant system and the difficulty of operation and increase equipment investment, so the power plant has always been driven by a motor. However, although the power of the draught fan motor is large, the power consumption is also large. The characteristics of the national power grid dispatching policy are as follows: When power plants reduce plant power consumption, the economic benefits of the power plant can be increased. Therefore, if the power plant is driven by a motor-driven draught fan to drive the turbine, the power consumption of the plant can be significantly reduced. This not only can enjoy the national grid dispatch policy, but also can effectively improve the efficiency of the draught fan operating at the half load condition. Huaneng International Co., Ltd. attaches great importance to reducing the power consumption of this plant, so it first opened up a domestic precedent and embarked on technological innovations, pushing wind turbines for wind turbines. Hangzhou Steam Turbine Co., Ltd. also relied on the performance of the drive field, especially the trust of Haimen Power Plant to Hangzhou Auto (Haimen Power Plant water-supply-pumped steam turbines are Hanggas products), and eventually won the bid with its own strength in the contest with SAIC and Dongqi. .
As the first set of induced draft turbines in China, the four turbines used in Haimen Power Plant have a lot of particularities, complexity, and challenges. At the same time, they have a very tight delivery time. Not only are the company's key products, but also Huaneng. The company’s must-have products. In order to strengthen the management of the unit, increase the execution of product contracts, and fulfill the mission on schedule, Hangzhou Steam Turbine Co., Ltd. has established a leading group and working group for key products of Haimen Power Plant Wind Turbine Fan Steam Turbine Co., Ltd. to promptly coordinate and supervise the production of the unit. . Haimen Power Plant also set up a research team headed by its general manager Li to coordinate the implementation of the project, and specifically sent the company’s deputy chief engineer Peng Dawei to attend the first technology held in Hangzhou Steam Turbine on March 19th. The liaison meeting, together with other design institutes, conducted full consultation and technical exchanges in various aspects such as design, commissioning, and production, and achieved positive results, creating favorable conditions for the implementation of the project and the smooth design and production of the unit.
In view of the high reliability requirements for the turbines for induced draft fans, the market prospects in the future will be broad, and the turbines driven by the induced draft fans in the 1000MW thermal power plant will probably become mainstream models. In addition to the five major power companies, Huaneng has initiated innovations, and other groups have also taken actions. The power plants and design institutes are all observing whether the innovation of Huaneng Power International Haimen Power Plant will succeed. If it succeeds, it will follow suit. Therefore, the success of the production of these four steam turbines and the success of the entire project will be of great significance to the Hangzhou Steam Turbine Stock Co., Ltd. It will not only fill the gaps in the country, but will also become one of the strategic products for the company to open up the future market. .

Zinc Cut Wire Shot

Zinc Shot is a very common Metal Abrasive used on Aluminium die casting parts and Zinc die casting parts. Zinc shot has a similar density but lower hardness. It could clean the surface of some soft casting parts without any damage while steel shot can not. Compared with aluminium, it is heavier and safer when shot blasting. Benefit from these advantages, Zinc shot is widely used in metal casting industry for surface treatment.

Longlived Zinc Shot is made from high qiality zinc wire by drawing, cutting and rounding. There are five shapes of Longlived Zinc Shot and they are as cut, G1, G2, G3 and even G4. The size is from 0.25mm-3.0mm. Of course, customize is available according to your requirement.

Longlived metal abrasive make your shot blasting cheaper, faster and cleaner.
