Dongturbo's leading product, thermal power turbine, has a complete product series of various types or combinations such as condensation, air cooling and heat supply. The power and parameters of the unit have developed from 1MW high-pressure turbine to 300 MW ultra-supercritical turbine. It has mature, reliable and advanced air cooling and heat supply technologies and complete auxiliary equipment, and is in the leading position in China.
With rapid development of the world economy and increasing shortage of the industrial energy, national policies for energy conservation and emission reduction are greatly implemented to move the industrial energy towards efficient, environment-friendly and sustainable development.
High-parameter, single-reheat and single-casing turbine units emerge at the right time to greatly improve the unit economical efficiency, fully use abundant waste heat generated in various industrial sectors, achieve energy conservation and emission reduction, and reduce costs arising from manufacturing and civil works.
To meet market demand and achieve energy conservation and emission reduction, Dongfang Turbine Co., Ltd. has independently and innovatively developed the 65 MW ultra-high-pressure single-casing single-reheat condensing turbine with the support of purchase orders.
Compared with the conventional high-temperature, high-pressure, non-reheat, straight condensing 65 MW turbine, Dongfang 65 MW single-casing reheat unit has low thermal consumption.
Compared with the ultra-high-pressure, high-temperature, reheat straight condensing 135 MW turbine in double-casing structure, the single-casing reheat turbine lowers the costs arising from manufacturing and civil works, and enhances the comprehensive competitiveness.
Compared with the ultra-high-pressure, high-temperature, reheat straight condensing 135 MW turbine in double-casing structure, the single-casing reheat turbine lowers the costs arising from manufacturing and civil works, and enhances the comprehensive competitiveness.
More importantly, the first unit shows excellent performance indicators and proves high economical efficiency and safety since being put into operation.
