Abstract
The utility model discloses a burner of a secondary reformer, in which the primary reforming gas entering the secondary reformer and the preheated air are mixed and burnt. The utility model comprises a first gas-guiding channel (1) leading into a primary reformer from the side surface, a combustion chamber (2) and a second gas-guiding channel (3), from the top of which air, oxygen-rich air or pure oxygen is led in, etc. The second gas-guiding channel communicates with the combustion chamber (2) via an oxygen nozzle (4). A gas distributor (5) is provided between the first gas-guiding channel (1) and the combustion chamber (2), and a metal bush (6) is provided on the internal wall of the second gas-guiding channel (3). The structure of the utility model can avoid the partial overtemperature of the combustion chamber and prevent the phenomenon of blowby between gas channels, and the utility model has the advantages of long lifespan, convenient maintenance, etc.
Description
The utility model belongs to chemical industry equipment, especially synthesis gas (ammonia, methyl alcohol etc.) manufacturing field.
Secondary reformer is the visual plant of chemical processes such as synthetic ammonia and methyl alcohol, hydrogen manufacturing.In synthetic ammonia, working off one's feeling vent one's spleen of one section conversion enters the secondary reformer head and carries out conversion reaction after the mixed combustion through the oxygen-containing gas (air, oxygen-enriched air, pure oxygen etc.) of preheating in burner (secondary reformer head) at about 650～800 ℃, makes remaining CH4 content in the reformed gas less than 1%.
Existing secondary reformer burner by the top import one section reformed gas first airtube, import second airtube of air, oxygen-enriched air or pure oxygen by the side, and burner is formed in combustion chamber etc.In actual use, find that this structure exists under the situation of using oxygen-enriched air or pure oxygen: one, undercompounding, the high-temperature region of its burning concentrates on chamber wall, makes the softening or fusion of chamber wall overtemperature; Two, airtube two is built by laying bricks or stones by high alumina castable cast or corundum, lacks air-tightness, and oxygen enrichment or pure oxygen are burnt by place, the crack ejection of refractory liner, thereby refractory material and pressure-bearing barrel are burnt out, and bring very big potential safety hazard.
The purpose of this utility model is a kind of novel secondary reformer burner of design, makes it to overcome the above shortcoming of prior art, has long service life, handling safety and advantage easy to maintenance.
The purpose of this utility model is to realize by following design.
The secondary reformer burner, by first airtube, the combustion chamber that are imported one section reformed gas by the side, and the top imports the compositions such as second airtube of oxygen-enriched air or pure oxygen.Be communicated with by oxygen nozzle between second airtube and the combustion chamber.Be associated with a gas distributor between described first airtube and the combustion chamber; The inwall of second airtube is lined with metal lining.
Owing between first airtube and combustion chamber, be provided with gas distributor, one section reformed gas axially or is tangentially evenly distributed along the combustion chamber, form a uniform airflow freezing mask, the counter-fire face is played a good protection.The setting of the second airtube metal inner lining has destroyed the generation condition that air gap is collaborated.Therefore, structure of the present utility model can be avoided the combustion chamber local overheating, and has prevented the danger that oxygen-enriched air or pure oxygen are collaborated in the flame retardant coating crack and produced, and has long service life, advantage safe and reliable, easy to maintenance.
Description of drawings is as follows.
Fig. 1 is a cutaway view of the present utility model.
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.Fig. 1 has shown the basic condition of the utility model structure, the secondary reformer burner is by first airtube 1, the combustion chamber 2 that import one section reformed gas, and the compositions such as second airtube 3 that import oxygen-enriched air or pure oxygen, be communicated with by oxygen nozzle 4 between second airtube and the combustion chamber 2.Be associated with a gas distributor 5 between first airtube 1 and the combustion chamber 2.Inwall at second airtube is equipped with metal lining 6.Oxygen nozzle 4 is porous or single hole structure.
When reality is implemented the utility model scheme, can also adopt some to be intended to increase the design of maintenance convenience, for example, oxygen nozzle is made tapered structure, when changing shower nozzle, help strip operation like this with old shower nozzle and flame retardant coating.
Claims (3)
1, secondary reformer burns device, make one section reformed gas entering secondary reformer and air, oxygen-enriched air or pure oxygen mixed combustion within it through preheating, burner is by first airtube 1 that is imported one section reformed gas by the side, combustion chamber 2, and the top imports compositions such as air, oxygen-enriched air or pure oxygen second airtube 3, be communicated with by oxygen nozzle 4 between second airtube and the combustion chamber 2, it is characterized in that, a): be associated with a gas distributor 5:b between described first airtube 1 and the combustion chamber 2): the inwall of described second airtube is equipped with metal lining 6.
