European Biomass Ash Workshop 2020

BIOFACT joined the European Biomass Ash Workshop 2020 by VGB and StandardConsult.

A tremendous increase in the use of biomass as a replacement fuel for coal for the production of heat and power causes the production also of huge quantities of biomass ash. The present-day situation is that this process has progressed far beyond the point where small quantities of ash could just be considered as unused waste. Utilization in any form is crucially important and this related to the ash chemistry characteristics.

We focused the participation on two keynotes:

  • Ash produced with the presence of additives (IFK).
  • Correct and representative ash sampling according to standards and best practices (Ørsted).

Participants are from IFK Stuttgart, HOFOR A/S, Ørsted Bioenergy & Thermal A/S, VGB PowerTech, TFZ, Agrotrade A/S, VTT,  DTU, Fortum, Emineral A/S and many others.

BIOFACT Fuel Dashboards 6.0 – newly developed graphical results

BIOFACT Fuel Dashboards 6.0 incorporates newly developed equilibrium phase diagrams, obtained with the last release of updated databases of the thermochemical equilibrium software.

Those in house developed graphical representation of equilibrium results (firstly presented in a PhD Thesis) allow to rapidly understand where the 100% liquid and 100% solid phase regions are located in ternary mixtures of major fuel ash oxides.

The most applicable diagram is included in the sample-specific Fuel Dashboard!

2 Separately cooled wear zone in furnace
3 Combustion chamber with Inconel® cladded walls
4 Ignition control with air
5 Advanced flame front control
6 VoluMix™ zone in 1st pass

When modeling and predicting the ash behavior in the boiler, it is important to consider local conditions: a cooled wear zone in furnace, the air settings, the washing system and the integrated baffle walls will have an effect into the thermal balance and therefore fuel transformations.
