Abstract
The utility model relates to a sintering igniter, particularly an automatic heat exchange igniter for low heat value gas. The utility model has the purpose that blast furnace gas is used for ignition and sintering, and the ignition temperature is raised. The utility model has the technical scheme that air preheating chambers 2, 3 are arranged above a body 1 of a sintering ignition furnace, and are communicated with an air inlet pipe and an air outlet pipe; the air outlet pipe is communicated with a burner nozzle, and a low-heat value gas pipe 7 is also communicated with the burner nozzle 6; ignition zones of the burner nozzle are densely arranged in multiple rows. Because combustion-supporting air is preheated, the igniting effect is ensured and the ignition cost of sintering ore is greatly reduced. The utility model has the advantages of reasonable structure, low production cost, good ignition effect, etc.
Description
The utility model relates to a kind of sintering ignition device, particularly adopts low-heat value gas heat exchange igniter voluntarily.
Both at home and abroad employed igniter generally has three kinds of patterns by the kind of use fuel in the SINTERING PRODUCTION, a kind of be applicable to solid-fuelled, as the coal powder point firearm; A kind of liquid fuel that is applicable to is as the heavy oil igniter; Another kind is applicable to gaseous fuel, and common is gas igniter.With regard to using gases fuel, can be divided into three types again, first kind of igniter that is to use the coke-stove gas of high heating value; Second kind for using low-calorie blast furnace gas igniter; The third is that calorific value falls between with the mixed gas is fuel ground igniter.Big-and-middle-sized sintering machine generally adopts the coke-stove gas igniting, and the small-sized sintering machine that coke-stove gas lacks has part to adopt the mixed gas igniting, and another part adopts the blast furnace gas igniting.Domestic large-type sinterer with the coke-stove gas igniting generally adopts the curtain-type igniter, and with the sintering machine employing line style igniter or the telescopic igniter of mixed gas igniting, the sintering machine of lighting a fire with blast furnace gas generally adopts telescopic igniter.The subject matter that exists in the prior art is the lower heat of combustion coal gas ignition, and ignition temperature is low, and flame is not concentrated, and is strict to gas pressure, is difficult to satisfy the SINTERING PRODUCTION arts demand.
The utility model purpose provides and adopts low-heat value gas heat exchange igniter voluntarily, all uses blast furnace gas igniting sintering, improves firing temperature, satisfies the SINTERING PRODUCTION arts demand, solves the problems referred to above that prior art exists.
The technical solution of the utility model is above the sintering ignition body of heater air preheating chamber to be set, and air preheating chamber is communicated with air intake duct and air escape pipe, and the air escape pipe is communicated with burner, and the low calorific value coal tracheae also is communicated with burner.
For flame is concentrated, the quantity combusted abundance, the flame temperature when reaching charge level is the highest, and an igniting section burner be to arrange intensive layouts more.
Since preheating combustion air, when using low-heat value gas, firing temperature can be brought up to 1050 ± 50 ℃, guaranteed the igniting effect, sintering deposit igniting cost reduces significantly, has stopped the coal gas influence substantially and has shut down, and improves the sintering machine operating rate.
The utlity model has characteristics such as rational in infrastructure, that production cost is low, igniting is effective, flame is concentrated.
Accompanying drawing is the utility model example structure schematic diagram.
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
In an embodiment, the utility model is made up of igniting body of heater, air preheating chamber, pipeline and burner, two air preheating chambers 2,3 are interconnected, be positioned at the top of igniting body of heater 1, air intake duct 4 is communicated with air preheating chamber 2, air escape pipe 5 is communicated with air preheating chamber 3, and air escape pipe 3 is communicated with some burners 6, and low calorific value coal tracheae 7 also is communicated with burner 6.For flame is concentrated, the quantity combusted abundance, the flame temperature when reaching charge level is the highest, and an igniting section burner be to arrange intensive layouts more.Combustion air is by the air preheating chamber 2,3 on air intake duct 4 inlet point stove body tops, utilize the heat in the ignition furnace to carry out preheating, air after the preheating enters burner 6 and the blast furnace gas mixed combustion that enters by the low calorific value coal tracheae by air escape pipe 5, because burner more than 6 intensive layouts of row and air are through preheating, the ignition temperature height, flame is concentrated, and guarantees the igniting effect.
Claims (2)
1, a kind of employing low-heat value gas with igniting body of heater 1, pipeline, burner 6 heat exchange igniter voluntarily, air pipe line and low calorific value coal air pipe 7 are communicated with burner 6, it is characterized in that sintering ignition body of heater 1 top is provided with air preheating chamber, air preheating chamber is communicated with air intake duct and air escape pipe.
2, according to the described employing low-heat value gas of claim 1 heat exchange igniter voluntarily, it is characterized in that igniting section burner is the intensive layouts of many rows.
