在此基础上,模拟了5种风口布置方案和送风量的改变对发电机层温度场和速度场的影响,获得了些可供参考的结论:在风量和送风速度不变的条件下,风口个数在( 14 ~ 22 )小范围变化时,工作区平均风速基本不变,大幅度增加风口个数( 36 ~ 44 )就会导致工作区平均风速的降低,风口数在14 ~ 36之间对工作区的温度不均匀系数影响不大,当风口数> 36时,温度不均匀系数随着风口数的增多而变小,速度不均匀系数一直随着风口数的增加而减少;在风口布置和尺寸不变的情况下,送风量变化时,工作区平均温度随送风量增大而降低,平均温度的降低量逐渐趋于减少,能量利用系数先是随着送风量的增加而增大,后随送风量增加而减少。
