Abstract
The utility model relates to a ceramic burner with a plurality of nozzles staggered and mixed up and down, which can effectively solve the problems of poor mixing of gas and air, and insufficient or unstable combustion. The structure of the ceramic burner is as follows: nozzles are divided into an upper row of nozzles and a lower row of nozzles, and each row of nozzles consists of gas nozzles and air nozzles which are arranged in a staggered way side by side; a plurality of gas nozzles are respectively communicated with a gas loop by a plurality of gas nozzle pipelines; a plurality of air nozzles are respectively communicated with an air loop by a plurality of air nozzle pipelines; gas is sprayed by the gas nozzle pipelines through the gas nozzles from the gas loop; air is sprayed by the air nozzle pipelines through the air nozzles from the air loop; directions of crisscross thin strand of gas and air flow sprayed from the gas nozzle and the air nozzle are staggered so as to rapidly and evenly mix the gas and air, and ensure sufficient combustion. The ceramic burner has novel structure, and complete and stable combustion, and can realize the rapid and even mixing of gas and air, reduce the air excess coefficient, increase the combustion temperature, reduce environmental pollution, avoid tempering when in burning and mixing, and ensure safety.
Description
One, technical field
The utility model relates to a kind of mixed ceramic combustor with multiple alternated nozzles of using on the blast funnace hot blast stove.
Two, background technology
Burner (perhaps burner) is the indispensable core apparatus of combustion furnace kiln plant, and whether good its performance and structure be directly has influence on fuel availability, the thermal efficiency of stove and whether satisfy energy conservation and environment protection.Finished from sleeve type burner for the burner that adopts diffusion combustion mode, progressively carry out the transition to the conversion of the rectangle burner of comb shape air nozzle, and develop into that the annular steady flame combustion technology of multiple nozzle spraying eddy flow mixing backflow preheat or annular multiinjector are staggered goes up the steady flame overheavy firing of air-flow turn-back pre-heating technology after the spray premixed combustion.Along with the development of combustion technology, the combustion intensity of low-heat value gas and the stability of flame are all greatly improved, coal gas and air preheat make that ignition temperature constantly increases, efficiency of combustion also progressively improves in the cooperation.But make a general survey of existing gas burner, especially use the burner of the blast furnace gas on hot-blast stove, owing to structure unreasonable causes coal gas to mix not good with air and/or the air-flow skewness usually is an occurrence, problems such as incomplete combustion that causes therefrom or combustion instability, heat load adjustment poor performance.Such hot-blast stove obviously can not satisfy blast furnace to the air quantity of hot blast and the requirement of wind-warm syndrome, let alone efficient, the energy-conservation and environmental protection of hot-blast stove, does not also accomplish the operation with security and stability under the high hot blast temperature.Therefore, improve the structure of burner, make the burning of its efficient stable just become the effective way that improves the hot-blast stove performance.
Three, utility model content
At above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides a kind of mixed ceramic combustor with multiple alternated nozzles, coal gas be can effectively solve and not good, incomplete combustion, problem of unstable mixed with air, the technical scheme of its solution is, comprises jet for gas pipeline, a plurality of air nozzle of coal gas circuit, air circuit, a plurality of jet for gas and connection coal gas circuit and jet for gas in the burner wall and is communicated with the air nozzle pipeline formation of air circuit and air nozzle; Wherein, nozzle is divided into two rows, and every row was made of side by side interlock alternate with air nozzle of jet for gas; A plurality of jet for gas are communicated with the coal gas circuit by a plurality of jet for gas pipelines respectively; A plurality of air nozzles are communicated with the air circuit by a plurality of air nozzle pipelines respectively, coal gas is from the coal gas circuit, through the jet for gas pipeline, spray by jet for gas, air, is sprayed by air nozzle through the air nozzle pipeline from the air circuit, the alternate thin thigh coal gas and the staggered rapid mixing of air draught direction of jet for gas and air nozzle ejection are even, guarantee fully burning.
This shows, the utility model novel structure, can realize evenly mixing fast of coal gas and air, burning can reduce excess air factor fully, improve ignition temperature, unburned fuel content is low, has improved the fuel utilization ratio and has reduced environmental pollution again, and spout is elongated, burning mixes can avoid tempering, guarantees safety.

Fig. 2 is a burner sectional top view of the present utility model.
Fig. 3 is another embodiment sectional front view of burner of the present utility model.
Fig. 4 is a burner sectional top view shown in Figure 3.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
By Fig. 1, shown in 2, the utility model is made of the air circuit in the burner wall and coal gas circuit and coupled air nozzle and air nozzle pipeline and jet for gas and jet for gas pipeline, burner nozzle is divided into two rows, every row is interlocked side-by-side the composition by jet for gas and air nozzle, last row's jet for gas 6 is communicated with coal gas circuit 1 by jet for gas pipeline 3, air nozzle 5 is communicated with air circuit 2 by air nozzle pipeline 4, under arrange jet for gas 6 and be communicated with coal gas circuit 1 by jet for gas pipeline 3, air nozzle 5 is communicated with air circuit 2 by air nozzle pipeline 4, on the evenly staggered alternate side by side horizontal circumference that is arranged in the combustion chamber internal face of a plurality of jet for gas pipes and a plurality of air nozzle pipe, and insert the combustion chamber with combustion chamber radially angled (inclination), air and coal gas interlock after the ejection from air nozzle and jet for gas respectively and mix, preheating is caught fire and is burnt, form the combustion-gas flow of rotation, and then enter the combustion chamber 7 that is connected with burner, after the spout ejection of alternate side by side coal gas and air by nozzle, the thin thin gas with various that forms mixes in moment at eddy flow and in the staggered process that flows forward, sufficient combustion, stable, this is that any in the past burner is all inaccessible, is the place of the utility model creativeness.
It is to be noted, Fig. 3, Figure 4 shows that the structure chart of another embodiment, after the two its difference only is air nozzle pipeline 4 and air circuit 2 is communicated with, different with the position that air nozzle 5 connects, the air nozzle pipeline is to be connected with last row's air nozzle among Fig. 1, the air nozzle pipeline is to be connected with the air nozzle of arranging down among Fig. 3, equally, jet for gas pipeline shown in Figure 1 is to be connected with last row's jet for gas, the jet for gas pipeline is to be connected with the jet for gas of arranging down among Fig. 3, that is to say, jet for gas pipeline 3 the same rows or the jet for gas of arranging down 6 are connected, air nozzle pipeline 4 the same rows or the air nozzle of arranging down 5 are connected, and every row's jet for gas and air nozzle interlock and come on the same horizontal plane.
By said structure as can be seen, the utility model burner is by the staggered side by side alternate evenly mixing in rotating downward process of multiply air draught, the coal gas air-flow of air nozzle and jet for gas ejection, sufficient combustion, combustion rate reaches more than 99.9%, can also select lower excess air coefficient for use, improve ignition temperature more than 200 ℃, significantly reduce pollution environment, getting well of its effect was not contemplated to, and economic and social benefit is huge.
