The efficiency of the SST-600 steam turbine convinced the customer Grupo Delta Sucroenergia. Siemens installed the biggest steam turbine in the sugar-ethanol sector with an power output of 73.5 MW. It is also the first turbine in Brazil to waive the use of gears with direct drive for the generator.

Customer: Sucrerie de Wonji Shoa

After processing sugarcane, the remaining bagasse is used as fuel for the boiler. The mill operates with a capacity of 31.5 MW, which produces enough energy to fully cover the demand for electricity and process steam

Customer: Illovo Sugar is Africa’s biggest sugar producer and has extensive agricultural and manufacturing operations in six African countries

Installed electricity generating capacity, fueled by renewable resources, annually provides around 90% of the group’s energy requirements

Steam turbine: 3 × D-R RS, power output: 2 × 1.8 MW / 1 × 2,6 MW, 2 of 3 delivered steam turbines are operated as shredder drives

Customer: Shivratna Udyog Pvt. Ltd., capacity: 2,500 tcd

“We found Siemens to be always approachable, quality-conscious, safety-conscious, and customer-oriented throughout the execution of the project. We are very much satisfied (…) and would recommend other prospective customers to prefer Siemens over other options,” commented the plant’s general manager.

Customer: The Semboro Sugar Factory is located 35 km west of Jember, Indonesia and started production in 1921 with 2103 hectares of sugar cane fields, capacity: 3,000 tcd

"We are pleased to thank Siemens (…) for their exceptional efforts to complete our project 1 × 7 MW BP STG set at Semboro, Indonesia. The STG set is running well and we also recommend you to other customers for installation of such STG set," says Norman Arifin, Technical Manager Semboro Sugar Factory.

Steam turbine: SST-300 (back pressure), power output: 7 MW, inlet steam: 18 bar(a), 325°C

Customer: Pravara Renewable Energy Ltd. owns and operates a bagasse-fueled cogeneration power project that processes roughly 5,000 tcd.

By installing an SST-300 steam turbine in 2012, the plant now operates at a capacity of 30 MW

Steam turbine: SST-300, power output: 30 MW, speed: 6,800 rpm, inlet steam: 107 bar(a), 535 °C

Customer: NSL Sugar Ltd. is one of the most efficient integrated sugar companies in southern India, capacity: 7,500 tcd

“We are highly satisfied with the support provided by Siemens … [the team] completed the project on time, and certain activities were completed ahead of schedule.” (S.C. Gupta, consultant at NSLSugar Ltd.)

Steam turbine: SST-300, power output: 35 MW, speed: 6,800 rpm, inlet steam: 106 bar(a), 535 °C

Customer: Ponni Sugars, capacity 2,500 tcd

This sugar mill was the first to successfully produce newsprint from sugarcane bagasse. It continues to pioneer firsts in the industry, such as using alternative fuel in its boilers. In 2010, the plant chose Siemens to deliver an SST-300 turbine, which today generates 19 MW of power – enough to keep the innovations coming.

Steam turbine: SST-300, power output: 19 MW, speed: 6,800 rpm, inlet steam: 111 bar(a), 520 °C 

Customer: Located in the Cam Lam district in the coastal Khanh Hoa province, Khanh Hoa handles roughly 3,000 tcd

Since choosing the SST-300 from Siemens, a very reliable steam turbine, the plant has not performed a major overhaul or changed any major parts in the past 17 years

Steam turbine: SST-300, power output: 25 MW, speed: 7,161 rpm, inlet steam ≤ 46 bar(a), ≤ 450 °C
