Embodiment 1

[0024] Embodiment 1: as figure 1 and figure 2 As shown, the heat supply incremental ignition holding furnace of the present invention includes a furnace body 1 and a burner assembly, the burner assembly is installed on the furnace body 1, and the burner assemblies include sequentially arranged The first row of burners 2 and the second row of burners 3, the calorific value of the fuel passed into the second row of burners 3 is higher than the calorific value of the fuel passed into the first row of burners 2. In this embodiment, both the first row of burners 2 and the second row of burners 3 are burners with a single fuel intake channel. The first row of burners 2 is provided with a low fuel value fuel passage 21 for feeding low fuel value fuel, and the second row of burners 3 is provided with a high fuel value fuel passage 31 for feeding high fuel value fuel. Both the first row of burners 2 and the second row of burners 3 are composed of a plurality of burners, and the plur...

Embodiment 2

[0028] Embodiment 2: as image 3 and Figure 4 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the second row of burners 3 is a burner with more than two fuel intake passages, such as a three-way burner, which can simultaneously supply Three-way burner heating method with high calorific value and low calorific value fuels and proportional adjustment. Adjust the supply ratio of high calorific value and low calorific value fuels according to the actual heat needs. While ensuring the quality of sinter ore, it can save the consumption of high calorific value gas to the greatest extent. Its working principle is basically the same as that of Embodiment 1, so it will not be repeated here.

Abstract

The invention discloses a heat supply progressively increasing type ignition heat-insulating furnace which comprises a furnace body and a burner component, wherein the burner component is installed on the furnace body; the burner component comprises a first row of burners and a second row of burners which are sequentially arranged along the heading direction of a trolley in the furnace body; and the heat value of the fuels led into the second row of burners is higher than the heat value of the fuels led into the first row of burners. The furnace of the invention has the advantages of simple and compact structure, low cost, wide application range and the like, the sintering quality can be improved and the production and operation cost can be reduced by using the furnace of the invention.

Description

technical field [0001] The invention mainly relates to the field of sintering process equipment, in particular to an ignition furnace for sintering process. Background technique [0002] Ignition is a very important link in the sintering process. In the modern sintering process, the ignition furnace is used to provide a high-temperature ribbon flame to the surface of the mixture, so that the solid fuel in it is ignited and burned, and the surface mixture is sintered under the heat release of the high-temperature flue gas of the ignition furnace and the solid fuel combustion. At the same time, sufficient oxygen is provided by the exhaust fan to transfer the heat accumulated in the surface layer to the next layer of mixture, so that the solid fuel in the next layer continues to burn, so that the sintering process proceeds rapidly downward. The sintering ignition system requires the ignition furnace to have sufficient ignition intensity and ignition temperature. The quality of...
