2And H
2O is main weak oxide property combustion product, therefore can realize the downflow type reducing roasting process.
Particularly, said burner is a plurality of, is uniformly distributed in furnace wall, the top inner face of said body of heater along the direction of said chain belt; Said plenum chamber is a plurality of, and the direction of the said chain belt in edge is uniformly distributed in the lower space in the said body of heater.The spacing of burner and plenum chamber is decided according to the actual requirements, with layering from top to bottom accomplish smoothly successively that preheating, fugitive constituent are caught fire, burning, reducing roasting process be purpose.
Further, the top of said chimney is connected with gas cooler and sack cleaner in turn.Flue helps environmental protection.
As preferably, said material distributing machine is the shuttle-type material distributing machine, and said discharging machine is a dissepiment formula discharging machine.
Further, the hopper outlet position of said material distributing machine is provided with the thickness of feed layer regulating gate.Thickness of feed layer through the control composite carbon containing pellet reaches best roasting effect.
The beneficial effect of the utility model is:
Adopt the utility model fast and efficiently the composite carbon containing pellet roasting to be made metallized pellet, and invest little, cost is low; Through adopting the chain-belt type structure to realize the function of operation, make the large-scale production of metallized pellet become possibility while burning.
