W型火焰锅炉在运行过程中改善燃烧器的二次风供风系统的配风结构是保证炉内形成良好的空气动力场和稳定燃烧的关键,但是目前此类锅炉的二次风供风系统的调节基本上是凭经验进行的。利用流体力学管路理论对此种锅炉二次风供风系统建立数学模型,并根据某电厂实际运行数据对二次风供风系统挡板开度进行的计算结果与现场运行情况基本一致,证明这种方法在实际工程应用中是可行的,为此类锅炉的二次风供风系统的挡板调节提供了一种理论依据。
W flame boiler in operation to improve the burner secondary air supply system with the wind structure is to ensure that the furnace to form a good aerodynamic field and the key to stable combustion, but the current secondary air supply system for such boilers The adjustment is basically based on experience. Based on the fluid mechanics pipeline theory, the mathematical model of the secondary air supply system for the boiler is established. The calculation results of the opening degree of the secondary air supply system based on the actual operation data of a power plant are basically consistent with the on-site operation, This method is feasible in practical engineering applications, which provides a theoretical basis for the baffle adjustment of the secondary air supply system of such boilers.
