摘　　要：采用热线风速仪对四角切向燃烧锅炉中的四角组合射流流场进行了冷态模化试验，研究了带侧二次风的直流燃烧器中一次风动量对一次风射流刚性的影响．The cold modeling test is carried out in tangentially fired boiler by hot stream velocity meter in order to investigate combined jets' field. Thus the influence of primary air momentum on the rigidity of primary air jet in burner with parallel secondary air is indicated.

关 键 词：射流刚性 燃烧器 侧二次风 锅炉 炉内过程
