Abstract
The utility model relates to a burner for a sintering ignition furnace, which solves the existing shortcomings of insufficient mixing between fuel gas and combustion air, relatively poor flame severity, relatively low combustion efficiency and the like. The novel burner for the sintering ignition furnace consists of a coal gas pipe 1, an air pipe 2, a spinning disc 3 and a coal gas spout 4, wherein a necking supporting tube 6 for coal gas necking 5 is provided on the coal gas pipe 1 by means of threaded connection, a whirlblast channel 7 is provided on the necking supporting tube 6 and diffusion holes are uniformly distributed on the tube wall of the coal gas spout 4 of the necking supporting tube 6. The burner for sintering ignition furnace is characterized in that the flame severity is favorable, the combustion is stable and the combustion efficiency is high as the fuel gas rotates with the combustion air at the opposite angle and is completely mixed with the combustion air, the internal structure is of the streamline type and the burner uneasily accumulates ash and is not easy to block.
Description
Technical field
The utility model relates to the ignition furnace of sintering machine, specifically belongs to the burner that ignition furnace of sintering machine is used.
Background technology
High-temperature ignition is an important link in the SINTERING PRODUCTION, and the purpose of igniting is the solid fuel point to be fought make the top layer fusion, by the negative pressure exhausting sintering process is carried out downwards.Firing temperature depends on the fusion temperature of sintering product, and this temperature range is usually at 1100～1300 ℃, and firing temperature often is controlled at 1150 ± 50 ℃ in the practical operation.Firing temperature is too high, can make the superfusion of sintering feed surface form air-locked duricrust, reduces bed permeability, and the vertical sintering speed that slows down reduces productivity ratio.Firing temperature is crossed when hanging down, and floating ash appears in the top layer, and quantity of return mines increases.At a certain temperature,, need enough durations of ignition, be generally about 60 seconds in order to guarantee surperficial bed of material institute calorific requirement.This just requires the air of burner, combustion gas mixing even, and flame rigidity is strong, flameholding.Conventional burner is owing to only to the combustion air flow-disturbing, therefore exist not enough: combustion gas and combustion air undercompounding, and flame rigidity is relatively poor, and efficiency of combustion is lower.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of employing bispin stream, flow-disturbing technology are provided, and it is more abundant that combustion gas, air are mixed, and flame rigidity is strong, flameholding, and the efficiency of combustion height prevents the novel sintered ignition furnace burner that stops up.
Realize the technical measures of above-mentioned purpose:
Novel sintered ignition furnace burner, by gas pipe, be contained in the outer air hose of gas pipe, be contained between gas pipe and the air hose and the spinning disk, the gas port that are connected with gas pipe are formed, it is: the reducing stay pipe that is processed with the coal gas reducing on the gas pipe by being threaded, on the reducing stay pipe, be processed with the eddy flow groove, on the tube wall of the gas port of reducing stay pipe, be evenly distributed with diffusion hole.
The utility model compared with prior art, its characteristics:
1, combustion gas is rotated with opposite angle with combustion air, and blending mutually mixes complete, abundant.
2, flame good rigidity, flameholding, efficiency of combustion height.
3, streamlined internal structure, burner are difficult for the collection ash, stop up.

Fig. 2 is the structural representation of former sintering ignition furnace with burner
The specific embodiment
Be described in detail below in conjunction with accompanying drawing:
Novel sintered ignition furnace burner is by gas pipe 1, be contained in the outer air hose 2 of gas pipe 1, be contained between gas pipe 1 and the air hose 2 and the spinning disk 3, the gas port 4 that are connected with gas pipe 1 are formed.It is processed with coal gas reducing 5 by being threaded on the end of gas pipe 1 reducing stay pipe 6 is processed with eddy flow groove 7 on reducing stay pipe 6, be evenly distributed with four diffusion holes 8 on the tube wall of the gas port 4 of reducing stay pipe 6.
Operation principle
When gas-flow during through coal gas reducing 5, for dwindling of caliber, gas flow rate is improved, thereby has improved combustion gas and Air mixing efficient, incorporation time is shortened.In order to strengthen the abundant mixability of combustion gas and air, improve mixed effect, so make the direction of rotation of eddy flow groove 7 opposite with the direction of rotation of spinning disk 3.And on the tube wall of gas port 4, be evenly distributed with four diffusion holes 8, by combustion gas to combustion air flow-disturbing once more, realize the mixing again of air, combustion gas, thereby make combustion gas and Air mixing more fully, fully, and realize the secondary mixing combination burning of air, combustion gas at gas port 4 places.
