Description
Technical field
The present invention relates to pulverized coal distributor field, and in particular to the adjustable moulded coal for 1000MW boiler controller system pulverized coal channels
Powder distributor.
Background technology
The commonly used unit pulverized-coal system of a large amount of capacity coal-burning boilers, blows each burner First air of formula pulverized coal preparation system now
Whether evenly distributed powder is to determine one of key factor of Combustion Operation of Boilers.The primary air velocity and coal of each burner of reasonable disposition
Powder concentration is to ensure boiler controller system safety, the essential condition of economical operation, is also the premise bar that low Nox combustion technologies are smoothly implemented
Part.Wind powder distribution between each burner is uneven, will directly affect catching fire and surely firing for burner outlet breeze airflow, causes flame
Deflection, wash away furnace wall, furnace load and temperature deviation, Nox discharge capacitys increase, it is also possible to cause coal in First air horizontal pipe
Powder is precipitated, and is caused plugging, is caused corresponding burner to burn out, or even is caused local reduction atmosphere strong and produced the local height of heating surface
The problems such as temperature corrosion or coking, booster, have a strong impact on the security and economy of unit operation.Because of primary wind and powder distribution inequality
The example for causing boiler to be not normally functioning is too numerous to enumerate.Peak regulation task is undertaken in unit and environmental requirement increasingly stricter feelings
Under condition, the evenly distributed sex chromosome mosaicism of wind powder shows important especially.Power industry standard《Thermal power plant coal dust preparation system design standard and
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 be evenly distributed, and its air quantity difference is not more than ± 8%, and coal powder distribation deviation is not 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 was applied earliest is the diffused coal dust that the 120MW unit E70 coal pulverizers that Huainan power plant the seventies are introduced are used
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 Germany 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 by grid by breeze airflow point
Some narrow slit flows are segmented into, two branch pipes are re-introduced into.Its intrinsic distribution deviation is ± 10%- ± 15%, adds drag characteristic and causes
Additional deviation, total distribution deviation can be bigger, it is impossible to the need for meeting 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.
The content of the invention
In order to solve problems of the prior art, the invention provides for 1000MW boiler controller system pulverized coal channels
Adjustable type pulverized coal distributor, substantially improves unit pulverized-coal system primary wind and powder partition characteristic, substantially eliminates Large Copacity coal-fired
The boiler various problems relevant with primary wind and powder partition characteristic.
