Abstract
Apparatus for supplying diluted gaseous fuel to not more than a lower limit combustion concentration at downstream of suction type sintering machine including a hood having similar width as a circularly-moving pallet and arranged above charged layer to surround the pallet in all directions, pipes disposed at upper position of charged layer in the hood and supplying the fuel air inside the hood, baffle plates formed by arranging plate materials having dog-leg shaped cross-section in plural rows and steps at intervals in the widthwise and height directions, respectively, of the hood to make each interval formed between adjacent plate materials in widthwise direction of the hood in each steps vertically alternate; fences having a void and arranged on both sides upper ends of the hood; vortex suppressing plates formed between fences at intervals having a void ratio, 20˜80%; whereby the gaseous fuel leakage supplied to the outside is prevented.
