    在此基礎上，模擬了5種風口布置方案和送風量的改變對發電機層溫度場和速度場的影響，獲得了些可供參考的結論:在風量和送風速度不變的條件下，風口個數在（ 14 ~ 22 ）小范圍變化時，工作區平均風速基本不變，大幅度增加風口個數（ 36 ~ 44 ）就會導致工作區平均風速的降低，風口數在14 ~ 36之間對工作區的溫度不均勻系數影響不大，當風口數> 36時，溫度不均勻系數隨著風口數的增多而變小，速度不均勻系數一直隨著風口數的增加而減少;在風口布置和尺寸不變的情況下，送風量變化時，工作區平均溫度隨送風量增大而降低，平均溫度的降低量逐漸趨于減少，能量利用系數先是隨著送風量的增加而增大，后隨送風量增加而減少。
