International workshop on 

High Temperature Corrosion in Biomass Combustion Installations

Wednesday 4 June 2014, 14:00 - 16:30

This workshop takes place as a side event
within the World Bioenergy Conference 2014 in Jönköping, Sweden

 

Workshop rationale and aim

Steam based Rankine cycles are still the standard in power generation from solid fuels, particularly for installations above a few MWe . As the efficiency of the Rankine cycle increases with live steam temperature, there is a continuous incentive to maximise steam temperature, however against the drawback of increased corrosion risk or more expensive, corrosion resistant superheater materials. 

There are however also other approaches that could enable increased superheater temperatures, e.g. by design changes (chlorine trap, empty pass, use of an external superheater) or operational changes (fuel dilution or leaching, fuel additives).

This workshop for equipment suppliers, researchers and end users provides insight in both design considerations for new plants, as well as cost effective measures for existing installations.
