Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, each structure the most involved to the detailed description of the invention of the present invention
Mutual alignment and annexation, the effect of each several part and operation principle etc. between the shape of part, structure, each several part are made further
Detailed description.
As it is shown in figure 1, this preheated sinter ignition furnace includes sintering ignition furnace body 1 and preheater 2, sintering ignition furnace is originally
Body 1 and preheater 2 are arranged on unitary design on same chassis, and burner 3 is arranged on sintering ignition furnace body 1 top to raw material
It is sintered.
As shown in Fig. 2 ~ 3, for this sintering ignition furnace pipeline configuration schematic diagram, cold air passes through air line 4 from cold air
Entrance enters in preheating section 6, and cold air is carried through hot air delivery pipe 43 by hot air outlet 42 after the heating of preheating section 6
Burning to burner 3, cooled coal gas conveying pipe is connected on factory's gas main supply for sintering ignition furnace；In like manner, if need right
Cooled coal gas preheats, and being directly passed through cooled coal gas in pipeline 4 can preheat cooled coal gas when preheating gas, repeat on
State the step of preheated air, flow to burner 3 through gas conveying tube 5 after cooled coal gas is preheated and use.
As shown in Figure 4, for the structural representation of preheating section 6 in preheater 2, preheating section 6 is arranged in preheating furnace, preheating section
