Description

Self-preheating type sintering ignition furnace capable of being assembled in split mode

Technical Field

The invention relates to the technical field of sintering ignition furnaces, in particular to a self-preheating type sintering ignition furnace capable of being assembled in a split mode.

Background

After the mixture is fed onto the sintering pallet, it is first ignited by an ignition furnace. According to the operation experience, the temperature of the ignition furnace is generally about 1250 ℃. The surface of the material layer is melted and the air permeability is poor due to over-high temperature, and the burning of the sinter is affected due to poor ignition on the surface of the material layer due to over-low temperature. In both cases, the yield of the sintered ore is reduced and the quality is deteriorated. Therefore, in order to ensure that the mixture is well sintered, an optimal ignition temperature is required for the material layer, and a reasonable air-fuel ratio is also required for sufficient combustion of the fuel gas, and therefore, it is very important to realize combustion control of the ignition furnace, which is a main type of the ignition furnace: the side burner type, the top burner type, the multi-slit type, the double inclined belt type, the hot air ignition type, the hot air sintering type and the low hot air type are developed along with the blast furnace iron making technology, the carbon distribution of the blast furnace is further reduced, the calorific value of blast furnace gas is too low (about 3135 kJ/m & lt 3 & gt), if the blast furnace gas is directly used for combustion, the ignition temperature is about 900 ℃, the requirement of sintering ignition cannot be met, so that a part of physical heat must be taken into consideration during process design, and the design of the blast furnace gas ignition furnace adopts an air and gas double preheating type to improve the ignition temperature.
