Combined Cycle technology is a highly efficient generator of electricity -- typically including a Gas Turbine connected to an electric generator with a Heat Recovery Steam Generator (HRSG) to capture the waste heat to produce steam. This steam in turn is used to further generate electricity through a Steam Turbine. Compared to Fossil Fuel fired power plants this high efficiency, shorter construction time, and lower capital cost makes the Combined Cycle power plant the predominant new plant choice. The diversity of Sulzer Pumps product lines provides highly efficient and reliable products for all the major services associated with a Combined Cycle Power plant including Boiler Feedwater, Cooling Water, Condensate Extraction and Auxiliary Services. Broad Product Portfolio The heart of these highly efficient combined cycle systems is the boiler feedwater pump. Today’s operation of Combined Cycle power plants demands flexibility of operation and unquestioned reliability for the Boiler Feedwater pumps. As the Gas Turbine and HRSG heat and steam output increases, so does the demand for larger capacity and higher pressure boiler feed water pumps. With its experience, broad product portfolio and local service capability, Sulzer provides the basis for dependable boiler feed water pump operation and power generation. Tests prior to installation New modular, standardized plant designs no longer use redundant equipment. To meet the high demands on dependability, factory pump tests are performed on all critical service pumps prior to shipping. Performance, vibration and when required hot water suction transient tests are performed to discover any potential problems before they occur in the field. Full test capabilities are essential services available from Sulzer to prove performance and reliability. Sulzer has capability for these tests in North America, Europe, Brazil, India and South Africa, over 20 test facilities worldwide . Sulzer’s full-service organization provides installation supervision assistance, operation training and maintenance services to ensure that operational expectations are met. Meeting service requirements Combined cycle power plants pumping systems must be reliable and available at all times, often meeting more than a dozen operating conditions as well as up to 200 starts and stops per year. As boiler ramp-up time is critical, the pumps are expected to handle quick thermal changes without internal wear or damage. Sulzer engineers fully evaluate the operating system and provide the customer with pump selection and equipment package to suit the most demanding service requirements. Centrifugal pump reliability and availability in today’s combined cycle power plants is dependent upon proper application, selection of matching features and equipment, shop testing, correct field installation, pump operation training, conducting routine maintenance and service work. Working with a full-service pump supplier such as Sulzer is essential to reliable pump installations -- essential for on-demand power to the customer
