Efficient and reliable gas turbine management

Continuous control of gas turbine efficiency

The Valmet DNA Gas Turbine Performance Monitoring application continuously calculates, displays and stores main gas turbine parameters. Calculations include gas turbine heat balance – with inputs, outputs and losses – and other key performance parameters. These cover inlet temperature, specific fuel consumption, heat rate, thermal efficiency and electrical efficiency. The application also includes the gas turbine wash monitoring feature for maintenance planning purposes. All calculations are built in accordance with generally accepted gas turbine standards, such as EN or ASME.

The application helps power plant maintenance and operating personnel detect potential problems in gas turbine operation and analyze those that have occurred. This prevents failures proactively – before they cause unpredicted shutdowns.

Additionally, extensive storage of history data enables long-term monitoring of gradual component deterioration, for significantly improved maintenance planning.
