Abstract
The utility model discloses an igniting thermal insulation furnace which uses blast furnace gas as the fuel and is used in the sintering operation. The utility model has the purposes that the flame jetted form burners is centralized; the heat intensity in the furnace is raised; the sintering is sufficient; the yield and the quality of sintered ore are raised; the energy consumption of the sintering operation is decreased. The utility model uses the measures that the burners on the upper part of a furnace roof uses a short flame type burners which are arranged in three rows and are arranged into a cone angle; the height of a furnace chamber is decreased, the height form the furnace roof of an ignition zone to a fuel surface is not larger than 500 mm, the height form the end of a heat insulation zone to the fuel surface is not larger than 200 mm, and the furnace roof of the heat insulation zone uses a slanted type, and gradually reduces to the height of the furnace chamber of the end of the heat insulation zone from the height of the furnace chamber of the ignition zone; the sintered ore is used to preheat and send wind at one time, the preheating mode uses a two-stage type, and the temperature after preheating is larger than 200DEG. C.
Description
The utility model relate to use in a kind of sintering circuit with the sintering ignition holding furnace of blast furnace gas as fuel, be the high temperature of solid fuel in the sinter mixture being lighted and kept certain hour, make sintering process more abundant.
The sintering ignition holding furnace mainly is made up of several parts such as body of heater, burner, supply air system and auxiliary equipments, body of heater divides igniting section and soaking zone, the body of heater outside is surrounded by furnace shell, body of heater inside is that promising sinter mixture provides the burner of heat on the igniting section furnace roof by furnace roof, the burner hearth that surrounds of furnace wall all around.Sinter mixture constitutes the bottom of burner hearth, sinter mixture is at first lighted through the igniting section, then, through soaking zone after-flame and fixed, at present, this is the sintering ignition holding furnace of fuel with the blast furnace gas, have following shortcoming: 1. generally adopt old-fashioned thimble tube burner, flame is long, and heat is not concentrated, the seed region temperature is low: 2. the preheating that do not have of once blowing and having, one time wind pushing temperature is low, is unfavorable for igniting: the employing belt-cooling machine that has, the waste gas of central cooler are made wind of igniting, but because dust content is big, heat resisting exhauster power consumption height, maintenance capacity is big; The employing sintering charge level that also has directly heats once air-supply, and still, the air themperature after the heating is not high enough, does not also satisfy production requirement; 3. light a fire and soaking zone burner hearth height, furnace height reaches 600-700mm, and soaking zone is the same with the furnace height of igniting section, thereby, weakened the fuel factor between charge level and burner hearth, be unfavorable for that sintering top layer material is fixed, influence the output and the quality of sintering deposit.
The purpose of this utility model is that the flame that burner is come out is concentrated, and strengthens calorific intensity in the stove, and sintering is abundant, improves the output and the quality of sintering deposit.
The purpose of this utility model is achieved in that
1. burner adopts the short-flame type, and three arrange puts and become cone angle to arrange, and flame is short, and sintering charge level heat is concentrated, the calorific intensity height;
2. the height of igniting section and soaking zone burner hearth reduces, radiation space reduces, calorific intensity in the burner hearth improves, igniting section furnace roof is apart from charge level height≤500mm, the terminal furnace roof of soaking zone is apart from charge level height≤200mm, the soaking zone furnace roof adopts tilting, from the section furnace height furnace height of aspect soaking zone end gradually of lighting a fire, can keep the calorific intensity in the burner hearth constant like this.
3 usefulness sintering deposit preheatings are once blown, and preheating method adopts two segment types, temperature after the preheating＞200 ℃.
4. the angle of adjacent two row's burners is 15 °.
The utility model has the advantages that: heat can be concentrated and effectively utilize in the burner hearth, calorific intensity improves in the stove, sintering circuit is finished easily, can improve the sintering deposit output and quality, and the energy consumption of reduction sintering circuit, the sintering deposit preheating is once blown and can also be reclaimed a part of waste heat, and furnace height reduces cost after reducing.
Fig. 1 is the schematic diagram of sintering ignition holding furnace.
Describe the concrete scheme that the utility model proposes in detail below in conjunction with accompanying drawing.
The sintering ignition holding furnace comprises the air preheater 7 of body of heater 4, combustor nozzle 3, supply air system etc., body of heater divides igniting section 1 and soaking zone 2, the body of heater outside is surrounded by furnace shell 5, body of heater inside is that promising sinter mixture provides the burner 3 of heat on the igniting section furnace roof by furnace roof, the burner hearth that surrounds of furnace wall all around.Sinter mixture 6 constitutes the bottom of burner hearth, sinter mixture is at first lighted through the igniting section, then, and through soaking zone after-flame and fixed, three row's burners are arranged on the furnace roof of igniting section, burner is the short-flame type and becomes cone angle to arrange, and adjacent two row folding angles are about 15 °, and the flame high-temperature region of burner just in time reaches the charge level of sintering deposit, and, three row's burners become cone angle to arrange, and concentrate in together when flame reaches charge level, and sintering is abundant.Again because the furnace height reduction, igniting section furnace roof is apart from charge level height≤500mm, the terminal furnace roof of soaking zone is apart from charge level height≤200mm, and the soaking zone furnace roof adopts tilting, from the section furnace height furnace height of aspect soaking zone end gradually of lighting a fire, thereby, strengthened the fuel factor between charge level and burner hearth, the calorific intensity in the burner hearth improves, and also acceleration of sintering is fully finished, thereby improve the sintering deposit output and quality, and reduce the energy consumption of sintering circuit.The sintering deposit temperature of coming out from ignition holding furnace is very high, come preheating once to blow with it, air preheater adopts two segment types, one section near burner hearth is high temperature section, another section is a low-temperature zone, the high temperature section sintering feed with the heat transferred air after, reach about 250 ℃ of equilibrium temperatures, low-temperature zone continues with cold air and sintering feed heat exchange the heat of sintering feed fully to be reclaimed, after the air of high temperature section and low-temperature zone mixes, the combustion air of burner as the blast furnace gas burning delivered in temperature＞200 ℃, helps blast furnace gas and lights, the blast furnace gas waste gas after burning is siphoned away by air-introduced machine, discharges through chimney.
