Transcription

1 Advanced Steam-Ex Inclined Drainer for dissolved pressurized hydrolyzate removal 31

2 Dissolved Sugars Evaporation (to to increase C5 Sugar Concentrations / remove acetic acid) Segregation good condensate quality Spray nozzle liquor distribution no plugging Constant circulation flows independent of capacity Easy access in case mechanical cleaning is required (internal platforms) Special design of discharge points of transfer piping to prevent accumulation of suspended materials and fibers 32

3 Evaporator Assembly Extensive internal supports of the element bundle to the vessel walls Vessels are normally transported complete: All internals in place All testing complete prior to shipping Bowater, Calhoun - I Effect 33

15 Biomass Boiler Business Is Relatively New Entry Has Been Highly Successful In 2006, decision to expand product portfolio with biomass power boilers based on fluidized bed technology. First biomass power boiler sold in Q1 2007, commissioned late 2008 and handed over Jan 2009 Rapid expansion of order intake for biomass power boilers; cumulative orders worth more than $ 400 million Biomass power boiler: turning biomass into green electricity. 45
