<p>PURPOSE: To purify rolling scale through a dust filter with no risk of fire while saving energy and to utilize energy of oil contained in a substance, e.g. rolling scale. CONSTITUTION: A continuous heating furnace 12 can be heated with hot exhaust air from a hood 11 located above the hot part of a sintering cooling machine 5 through a pipe 23. Furthermore, the continuous heating furnace 12 is conducted with the ignition furnace 3 of a sintering machine 1 through a pipe 24 and hot exhaust air from the sintering cooling machine 5 is introduced, as combustion air, into the ignition furnace 3.</p> |
