摘要
介绍了Siemens公司生产的V94.3A 350 MW单轴燃气蒸汽联合循环机组采用的由24个干式低NOx(DLN)混合型燃烧器组成的环形燃烧系统,它具有低NOx质量浓度、低CO体积分数、低压降和高运行灵活性等特点,该系统采用扩散燃烧模式和预混燃烧模式,并且通过这两种模式间的切换来实现低NOx的排放。
An introduction is being presented to an annular combustion system made up of 24 dry low NOx（DLN） pre-mixed burners for a V94.3A 350 MW single-shaft gas turbine combined cycle unit manufactured by Siemens,which is featured by low NOx volume fraction,low CO volume fraction,low pressure drop and high operation flexibility.The system adopts diffusion and pre-mixed combustion mode,and the low NOx emission purpose is achieved by switching over between above two modes.
