Abstract
The utility model relates to a double preheated type sinter ignition furnace which uses blast furnace gas as the fuel. An ignition zone (1) and a warm holding zone (4) are arranged in an ignition furnace, and a partition wall (3) is arranged between the ignition zone (1) and the warm holding zone (4). A heat exchanger (5) of the blast furnace gas and an air heat exchanger (6) are arranged in the warm holding zone. The utility model is provided with the heat exchangers in the ignition furnace, and the coal gas and the air are preheated. Thus, the furnace temperature of the ignition zone is raised, favorable conditions are provided for replacing the coke oven gas by the blast furnace gas, the energy source is saved, and the cost is reduced. The furnace body has simple structure, and thus the utility model is particularly suitable for sintering iron ore into sintered ore.
Description
It is the ignition furnace of sintering machine of fuel with the blast furnace gas that the utility model relates to a kind of.
Existing ignition furnace structure can not preheating, makes blast furnace gas and combustion air all be in normal temperature, because blast furnace gas calorific value mostly is lower than 3900KJ/M
3, thereby the ignition furnace temperature only is about 1000 ℃, than low 150～200 ℃ of normal temperature, increases fuel consumption, influences sintering quality.The ignition furnace that has, though take hot blast combustion-supporting, heat exchanger is located at outside the sintering machine, and connecting line is long, and floor space is big, the cost height, the flue gas of heat exchanger can not be introduced the sintering charge level and discharging separately simultaneously, causes environmental pollution.
The purpose of this utility model is that a kind of two pre-heated sintering ignition furnace that is provided with double heat exchanger in stove will be provided.
Introduce the technical solution of the utility model below in conjunction with drawings and Examples.
Fig. 1 is a schematic diagram of the present utility model.
With reference to accompanying drawing, the utility model is provided with igniting section 1 and soaking zone 4 in ignition furnace, and there is partition wall 3 centre, and blast furnace gas heat exchange device 5, air heat exchanger 6 are arranged in soaking zone, and chews 7 for heat exchanger provides the burning of thermal source.
Normal temperature blast furnace gas and air are sent into heat exchanger 5,6 respectively, deliver to burn through pipeline again and chew 2 mixing, in igniting section 1 internal combustion, light the sinter mixture that is transported by chassis 8.
The utility model is provided with heat exchanger in ignition furnace, with coal gas and air preheat, igniting section furnace temperature is improved, and provides advantage for blast furnace gas replaces coke-stove gas, saves the energy in a large number.The utility model furnace binding is simple, is specially adapted to sinter iron ore powder into sintering deposit.
Claims (1)
1, a kind of two pre-heated sintering ignition furnace is characterized in that: igniting section (1) and soaking zone (4) are set in ignition furnace, and there is partition wall (3) centre, and blast furnace gas heat exchange device (5) and air heat exchanger (6) are arranged in soaking zone.
