Product Description

2 poles steam turbine generator

QNP steam turbine generator uses closed-loop air self-circulation ventilation.

The rotors of turbo-generator under 50MW adopt indirect ventilation cooling method;

The rotors of 50MW and above turbo-generator is directly ventilated and cooled; an auxiliary groove is machined under the rotor winding trunking; air vents are machined on the rotor windings; with the action of the fan head and the centrifugal pressure head of the air vents, the rotor windings are directly cooled by air from the auxiliary groove and air vents.

Technical performance analysis:

1.Output margin

The series of steam turbine generator of QNP retain 10% output margin.

2.Loss and efficiency

The steam turbine generator of QNP optimized its design and farthest minimized the additional loss and wind abrasion of generator under no-load and short-circuit condition, improved the efficiency of the generator, in general, QNP steam turbine generator`s efficiency is 0.2% higher than domestic similar models in this industry. It is higher than the national efficiency standard on the same capacity level. For example: QNP 15MW steam turbine generator`s efficiency value can reach 97.65%, and the national standard value is 97%.

3.Operational reliability

QNP`s steam turbine generator adopts advanced manufacturing technology, especially the rotor`s overspeed test uses high-speed dynamic balancer, the rotor`s balance precision has been greatly improved, and the rotor`s vibration value is decreased. So that the steam turbine generator`s running availability factor has been improved, and the unit`s forced outage rate is decreased. At present, the availability factor of the steam turbine generator can reach about 99%, and the forced outage rate fell to 0.04% to 0.4%. Overhaul interval is up to 5 years. And the unit life can reach to 35 to 40 years.

QNP is the largest and leading private manufacturer of steam turbines and generators in China. Located in Qingzhou city, one of the nine ancient prefectures of China, QNP was founded in 1993 and covers an area of 20 hectares, with total construction area of 90,000 square meters.
