Abstract

PURPOSE: To decrease the fuel unit of ignition maintaining and improving the productivity, by limiting the layer thickness of drying preheating zone of blending raw material in a specific ratio of the whole layer thickness, at the time of manufacturing sintered ore by Dwight.Loyd sintering machine.
CONSTITUTION: Upper layer part of blending raw material is preliminary dried before ignition in the extent of 5W20% of the whole thicknes layer, preferably 7W 15%, by blowing hot air from the hot air supply apparatus 19 equipped between the ignition furnace 6 and ore feeding apparatus, after supplying the blending raw matrial on the pallet 7 at Dwight.Loyd sintering machine. By the above operation, fuel primary unit of coke or COG etc. is decreased at the ignition furnace and the quality of sintered ore is improved and also, generating quantity of Nox is able to control.
