5、for Continuous Carbon ReductionWhat is FBR(Fluidized Bed Reactor)Silicon?The Siemens Process01.02.03.The“seeds”grow larger and heavier and heavier until they leave the chamber when they have reached sufficient size.Silicon“seeds”are inserted into a chamber filled with hot,high purity silane gas pass

6、ing through it.The gas flow“fluidizes”the silicon seeds which liquefy as the silane gas decomposes and deposits layers of silicon on them:catalytic reaction.Hydrogen consumption（Nm/t）Power Consumption(kwh/kg）Labor（person/10kt）Water Consumption（t/t）61%LaborCost76%Power Consumption18%Water Consumption
