Saving potentials

Optimization of fuel and air distribution in a coal fired utility boiler is one way to reduce the consumption of fossil fuel and lowering CO₂ emissions correspondingly.

The technical feasibility of real time coal flow distribution measurement, and the benefits of coal flow balancing have been demonstrated. The differences between pre- and post optimization were measured by comprehensive testing.

Combustion optimization by dynamic coal flow balancing may result in:

- reduction of No_x and CO₂
- reduction of excess air
- reduction in LOI
- reduction in opacity events
- reduction in water wall wastage
- reduction in auxiliary power
- more balanced furnace temperatures
- extended lifetime of materials (less maintenance)

 

 

Thus gaining:

- increased efficiency up to 0,5%
- increasing availability
- financial savings up to 800.000 US$ per annum

The return of investment (ROI) period for dynamic coal flow balancing is 1-3 years
