| Abstract: | Study on characteristics of start up process using hot flue gas is carried out in a simulated Pressurized Fluidized Bed Combustor(PFBC) with a similar water cooled distributor and wind box configuration to the pilot scale PFBC boiler.Coal acceptability is tested in starting up the fluidized bed using hot flue gas based on four different coals including bituminous coal,anthracite,lean coal and gangue blending anthracite.Effects of parameters,such as bed temperature when coal is fed,coal feeding rate,in bed heat transfer tubes,static bed height,hot gas temperature and flow rate,on the start up process is investigated thoroughly.Variations of elevation rate of the bed temperature under various conditions are also conducted. |
