3 Terms and Definitions
The following terms and definitions defined in GB/T 50408 apply to this document:
3:1
It is composed of main exhaust fan, large flue, bellows and bellows branch pipes, and air regulating device, and provides combustion-supporting and heat-conducting air supply for the production process of sintering machine:
to the system:
3:2
effective wind effectiveair
Under the action of the main exhaust fan, it passes through the mixture layer, and enters the air for the combustion air of the sintering fuel and the transfer of heat for the sintering mixture:
box of air:
3:3
air leakage ineffectiveair
Ineffective air entering the exhaust system of the sintering machine:
3:4
Air leakage before the outlet of the large flue of the sintering machine or before the inlet of the dust collector:
3:5
Air leakage of the exhaust system of the sintering machine:
Note: It is the sum of all leakage air volumes before the main exhaust fan inlet of the sintering machine:
3:6
Under specific working conditions, the air volume at the outlet of the large flue or the inlet of the dust collector:
