Adapting coal power plants for flex-fuel use

 

References Valmet 100 % conversion from coal to renewable fuelsCustomer: Valmet Power Oy

 CHALLENGE

Maximise the use of low quality, low cost fuels like agro biomass.

 SOLUTION

VTT undertook experimental trials in a pulverised coal-fired boiler that had been retrofitted into a fluidised bed boiler. Two entire 100 MW pulverised coal units were transformed into 75 MW fuel-flexible biomass-fired units for approximately one third the cost of building new units.

 BENEFIT
  • Decarbonisation of existing coal power plants has been proven both feasible and economical
  • Harness an existing waste stream (sunflower husks) to produce power
