Valmet DNA Boiler Sootblowing Manager
Valmet DNA Boiler Sootblowing Manager calculates, stores and displays the boiler heat transfer characteristics that indicate fouling and deposit accumulation on heat transfer surfaces. These values can be used both to short and long term monitoring thus helping to detect gradual changes in boiler heat transfer and to optimize sootblowing.
Benefits
The application helps the plant personnel to avoid unplanned shutdowns by regular monitoring of the heat transfer coefficients, comparison to previous years and changing the sootblowing sequence and target when needed. The starting levels of the heat transfer coefficients in the beginning of operating seasons also indicate the success of washing of surfaces during maintenance stoppage. This data can be used to improve the washing methods and to shorten the duration of the maintenance.
Features
The application includes calculation of the following heat transfer characteristics for each heat transfer surface:
- Actual heat transfer rate (steam/water side) [MW]
- Actual heat transfer coefficient [kW/K]
- Load-compensated heat transfer coefficient [kW/K]
- Reference heat transfer coefficient after sootblowing [kW/K]
- Reference heat transfer coefficient before sootblowing [kW/K]
- Extra fuel consumption due to fouling [MW]
