摘　　要：针对珞璜电厂引进法国Stein公司 360MW的W型火焰锅炉进行了冷态模化研究 ,采用热线风速仪对炉内流场进行测试 ,研究了燃烧器配风 (改变各次风动量流率比 )对炉内空气动力场的影响规律 ,并对所得结果进行了比较与分析。研究表明 。Cool state experimental investigation has been made in a model of the 360MW W shaped flame boiler introduced by Luohuang Power Station from Stein Corporation in France.Measuring flow field in the boiler with a hot -wire anemometer,and studies of regularity on the influence of momentum flow ra te of air flow from vari ous spouts of burners on aerodynamical field in boiler are made in the paper.Meanwhile,analysis and compari son to experimental res ults are also carried out.It is manifested that suitable match of rate of air f lows from vari ous spouts of burners for the organization of combustion conditi ons in W shaped flame boiler is very important.
