| Abstract: | The aerodynamic and fluidization characteristics and combustion condition improvement of an air distributor with guide plates in a fluidized bed boiler are discussed. Test data show that the functions of the guide plates are as follows: (a) decreasing the local pressure doop in the air button region; (b) increasing the circulation ratio of the air stream near the distributor region; (c) improving the fluidization quality and coal combustion efficiency; (d) lowering the fluidization number (v/vmf) with good fluidization condition. |
