On the basis of developing CFB boiler used for 210 MW unit

the key technologies of manufacturing large CFB boilers has been systematically studied

and the schematic design of home-made CFB boiler for 330 MW unit being carried out

the structure design of key components and scaling-up characters being analysed and numerically simulated.Results in practical operation show that the first home-made CFB boiler for 330 MW unit boasts uniform fluidization

stable bed body

as well as good characters for adjustment of bed temperature and steam temperature

each parameter of performance reaches the designed value.At the same time

it shows that the key technologies of large-capacity CFB boilers have been completely mastered in China.
