Wärtsilä Corporation has been awarded a contract by Surma Energy Ltd, a company of Larfarge Surma Cement Ltd, to deliver a 30 MWe power plant for a new cement plant of Lafarge Surma at Chhatak in Bangladesh. The power plant will be designed and constructed by Wärtsilä under an Engineering, Procurement and Construction (EPC) contract worth approximately 15 million Euro. The power plant ordered in December is due for handing over in the first quarter of 2005.
The new cement plant will initially have an annual production of 1.2 million tonnes of high-quality cement. The raw material will be transported from its own quarry by a 17 km conveyor belt.
The power plant will comprise four Wärtsilä 18V34SG gas engines and two Wärtsilä 18V200 diesel engines. The 18V34SG-engined sets will each deliver 5990 kWe at 750 rpm, and the 18V200 sets 3450 kWe at 1500 rpm. The gas engines will be for normal base-load operation on natural gas while the 18V200-engined sets will be for peak-load operation during the starting of main motors in the cement plant.
The plant will operate independently of any external network. This makes the project technically demanding in terms of stringent voltage and frequency variation. The cement plant has a number of large electric motors, which create high starting loads. Yet the voltage and frequency drops as these motors are started must be restricted because the drive system of the long conveyor belt is sensitive to voltage and frequency variations.
The plant is in north east Bangladesh. The location is very remote without proper road connections for heavy transport. Thus the generating sets will be delivered by river transport. But this is only possible between May and October when the river levels are sufficiently high (usually 7m above levels in the ‘dry’ season).
