Computational methods》(DL/T5154-2002) expressly provide in the 8.1st article, it is each with layer burner to medium-speed pulverizer unit pulverized-coal system
Coal dust and air between primary air piping should evenly distribute, its air quantity difference be not more than ± 8%, coal powder distribation deviation no more than ±
10%.Pulverized coal distributor is the device that breeze airflow is uniformly distributed to some branch pipes, is just had early in the fifties abroad
Using what the country applied earliest is the diffused coal dust that the 120MW unit E70 coal pulverizers that Huainan power plant the seventies are introduced use
Distributor；The eighties, Dou He power plant, Yaomeng power plant and Chaoyang power plant introduce employed in unit or transformation process diffused,
The pulverized coal distributor of grid type and German BABCOCK.The nineties, the grid moulded coal developed by domestic relevant R＆D institution
Powder distributor is applied successfully on the 200-300MW units of the power plant such as first Yangshan, Longkou, Fengcheng successively.It is existing
Grid pulverized coal distributor is that performance is best in all types distributor, and grid pulverized coal distributor is divided breeze airflow by grid
Some narrow slit flows are segmented into, are re-introduced into two branch pipes.Its intrinsic distribution deviation is ± 10%- ± 15%, is caused plus drag characteristic
Additional deviation, total distribution deviation can be bigger, it is impossible to meets the needs of large sized unit safety and economic operation, solves wind powder point
Key with offset issue be in distributor so that enter each branch pipe air quantity and powder measure it is uniform.
