烧结过程中要使燃料中的碳素充分燃烧,供给的空气要有一定的过量。空气过剩系数就表明空气过量的多少。它的定义是:空气过剩系数(b)=(实际空气量)/(燃烧所必需的空气量)
Sintering process to make the fuel in the full combustion of carbon, air supply to have a certain amount of excess. The excess air factor indicates how much air is in excess. It is defined as: air excess coefficient (b) = (actual air volume) / (air volume required for combustion)
