In order to meet the market demand, Shanghai Turbine Works Co., Ltd. has developed very perfect 300MW steam turbines (including: 300 MW, 330 MW, 350 MW) through years of independent innovation and development. And the 300MW steam turbines cover different parameters (subcritical, supercritical), different functions (steam condensation, one-off steam extraction, and two-time steam extraction) and different cooling methods (humid-cooled and air-cooled), different rotation speeds (3000r/min and 3600r/min), which can meet the needs of different users. The most popular models are as follows:
The supercritical units can be divided into different types, such as supercritical, intermediate reheating, single axis, high and middle pressure cylinder, pure condensation, extraction condensation and double extraction condensations. The steam inlet parameters are 24.2MPa/566℃/566℃.
The subcritical units can be divided into different types, such as subcritical, intermediate reheating, single axis, high and middle pressure cylinder, pure condensation, extraction condensation and double extraction condensations. The steam inlet parameters are 24.2MPa/566℃/566℃.
In order to meet some foreign market demand, our company independently designs and manufactures 60Hz units. And the 60Hz units can be divided into different types, such as ultra high pressure, subcritical, supercritical.
- Shanghai Turbine Works Co., Ltd. produced China's first subcritical intermediate reheating 300MW steam turbine in 1971.
- Our company introduced the design and manufacturing technology of 300MW Steam Turbine from Westinghouse Electric Co., Ltd. in 1981. And our company has formed a mature design system after several optimizations, which can meet the requirements of different users.
- Our company established corresponding technical system platform while improving the product quality. Such as the design system for movable vane of triplet regulating stage, the design system and testing technology for centerless rotor, the design system for high-temperature bolts, the design system for movable vane with its own shroud.
- 300MW steam turbine has excellent performance. And it can be divided into different types, such as steam condensation, air-cooled and steam extraction. In addition, our company developed a series of new products for 300 MW units in order to meet market demand, such as double steam extraction, steam extraction & air cooling and supercritical units, which expanded product species and enhanced the market competitiveness. Now our company occupies a leading position in the industry.
- As of February 2009, this series of products accounted for nearly 50% share of the market. And contracts had been signed for 4 60Hz units(exported to Brazil), 2 supercritical units and 87 units(including 16 units for international customers). In addition, 195 subcritical 300 MW units (including 5 units for international customers) had been put into use and 14 units (including 4 for international customers) had been being installed.
- Our company produces at least 32 300MW kilowatt thermal power units per year by taking a series of measures, such as the separation of non-core businesses, increase production capacity and the use of socialized division of labor.
- 169 units of 300MW steam turbine have been put into commercial operation for the past many years, mainly including Shiheng Power Plant(#5, #6, #7 , #8 , #5 and # 6 at Phase III project), Qingdao Power Plant(#1, #2, #3, #4), Weihai Power Plant(#3, #4), Laicheng Power Plant(#1, #2, #3, #4), Heze Power Plant(#3 , #4), Manasi Power Plant(#7, #8), Muzzarfarge Power Plant(#4), Chashma Power Plant(#1), SAHAND Power Plant in Iran (#1, #2), Yamunanagar Power Plant in India(#1).
