Siemens supplies gear units for coal-fired power plants in India under major BHEL order

- Supply of complete gear units and gear components for vertical mills for coal grinding
- Total demand covered for the next three years
- Rugged design comprising a bevel gear stage and planetary stage for high performance and reliability even in a harsh environment

The Siemens Drive Technologies Division will be supplying large gear units and gear components for vertical mills to Bharat Heavy Electricals Ltd. (BHEL) to cover their overall demand in the coming three years. BHEL is a leading manufacturer of mechanical and electrical components for power plant and energy technology based in New Delhi, India. Since India's demand for energy is growing rapidly, coal-fired power plants are constantly being built and expanded. The Flender gear units from Siemens are deployed in vertical mills with an output of 800 and 1000 kW, which are used for coal grinding in the power plants. Due to their rugged design, these powerful and reliable drives are ideal for the harsh ambient conditions in power plants and permit smooth operation. The value of the order is in the (Euro) double- digit million range.

The Flender gear units supplied by Siemens consist of a combination of a bevel gear stage with a planetary stage. Thanks to the special design developed by Siemens for use in coal grinding, a high power density is achieved and at the same time the
forces from the grinding operations are transferred to the foundation via the gear casing. The operating company thus benefits from smooth operation and very fine coal grinding, which is required for efficient combustion.

"We see this major order as a convincing vote of confidence from BHEL in reliability of the Flender gear units and the commitment and cooperation of our employees," says Dr. Bernhard Hoffmann, Head of the Mechanical Drives Segment in the Siemens Industry Sector

BHEL is India's largest engineering and manufacturing company of its kind engaged in the design, engineering, manufacture, construction, testing, commissioning and servicing of a wide range of products, systems and services for the core sectors of the economy, like Power, Transmission, Industry, Transportation, Renewable Energy, Oil & Gas and Defence. BHEL has its headquarters in New Delhi, and currently employs around 49,390 people. It is involved in more than 150 power generation projects. As a leading plant constructor in India, BHEL has already successfully cooperated with Siemens in the past and purchased 60 gear units for vertical mills last fiscal year. Siemens will be supplying Flender complete gear units and gear components for vertical mills for coal grinding by order of Indian large-scale enterprise Bharat Heavy Electricals Ltd.
