Heat recovery steam generator performance monitoring

Valmet DNA Heat Recovery Steam Generator Performance Monitoring (DNA HRSG Monitoring) application calculates, stores and displays the main performance parameters that indicate the condition and operating efficiency of the HRSG. The calculations are based on HRSG heat balance and built in accordance with appropriate standards.


  • The application includes calculation of the HRSG heat balance and the main performance parameters, such as the HRSG efficiency by input-output method or by heat loss method.


  • The DNA HRSG Monitoring application provides the power plant maintenance and operating personnel with a tool that helps to detect potential problems in HRSG operation and analyze the problems that have occurred. This contributes towards proactively responding to failures before they cause unpredicted shutdowns.
  • The extensive storage of history data also enables long- term monitoring of gradual component deterioration and thus improves scheduling of maintenance.
  • The DNA HRSG Monitoring application is linked seamlessly to the overall automation applications, which guarantees efficient collaboration between plant management and plant control.
