Coal Fired Power Plant



Boiler Data

  • 660 MWe, supercritical boiler
  • 2079 t/h steam throughput, 243 bar, 568°C
  • Fuel: Sub-bituminous coal
  • 3rd train: width 24.4m
  • 4 x Shock Pulse Generator TwinL in 3rd train in operation 04/2018
  • Shock Pulse-IntervaI: 1h/ TwinL
  • SPGs work in addition to existing sootblowers by adding the third pass with primary reheater, primary superheater and economiser.
  • 2nd phase, a further 4xTwinL were installed in 11/2019 for further cleaning optimisation and reduction the steam sootblowers into operation.

Improvement of the cleaning process

  • Very good cleaning effect due to significant reduction of soiling in the 3rd pass
  • Reduction of the flue gas temperature at the economiser outlet to 380 °C, immediately after the 2nd phase
  • Before: Manual intermediate cleaning on a monthly basis
