涡流的可控性和煤种适应性

Vortex Controllability and Adaptability to Dif-ferent Coal Categories

本文提出的钝体可控涡稳燃器可改变回流区尺寸和反向质量回流率,冷热态试验结果表明,这对劣质煤的着火、稳燃和锅炉低负荷的适应性都是行之有效的.

Dimension changeability of recirculating zone and reversing mass flow rate possible with obtuse controlled vortex stabilizing burners are discussed by the authors. Cold test results demonstrate its effectiveness for ignition and stable combustion of low-grade coal and steady operation at low boiler load.
