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．
A hot-wire anemometer was used to simulate the four-corner combined jet flow field in the tangential fired boiler. The influence of the primary air momentum on the primary air jet stiffness in a DC combustor with side secondary air was studied.
