Embodiment 1

[0042] Preparation of catalyst: Elemental iron, elemental aluminum, elemental platinum, sodium chloride, refined molybdenite and refined manganese ore are respectively crushed. Mix 0.7 kilograms of iron powder, 4 kilograms of aluminum powder, 0.1 kilograms of platinum powder, 1 kilogram of sodium chloride powder, 3 kilograms of molybdenite powder and 1 kilogram of manganese ore powder with water glass, and place them in a square mold. Compression molding at atmospheric pressure.

[0043] Combustion of steam cracked mixture: using figure 1 The burner burns, the pipeline for conveying the steam cracked mixture is connected to the multi-port joint, so that the mixture of steam cracking flows into the central fluid channel, and the pipeline for transporting methanol is connected to the multi-port joint so that the methanol flows into the peripheral fluid channel. .

[0044] Close the valve that controls the water vapor outlet, and the water vapor is passed into the pressure vess...

Embodiment 2

[0046] The procedure was carried out in the same manner as in Example 1, except that the weight ratio of the mixture obtained by steam cracking to the methanol was 3-10.

Abstract

The invention provides a burner tip. The burner tip is characterized by comprising at least two fluid passages, wherein an atomization device is arranged in at least one fluid passage. The invention further provides a burner with the burner tip and a steam-cracked hydrogen burning method employing the burner. In the steam-cracked hydrogen burning method, a mixture obtained by steam cracking is introduced into one fluid passage, and a liquid fuel is introduced into the fluid passage with the atomization device. When the burner with the burner tip is adopted for simultaneously burning gas and liquid fuels, the fuels are uniformly mixed and completely burnt, so that cost is further lowered, and atmospheric pollution is reduced.

Description

technical field [0001] The present invention relates to a burner nozzle, a burner having the burner nozzle, and a steam cracking hydrogen combustion method using the burner. Background technique [0002] Among the current burners, mainly single-fuel burners, there are also a small amount of dual-fuel burners. The current dual-fuel burner burns one state (such as liquid) fuel in a certain period of time, and burns another state (such as gaseous) fuel in another time period, and cannot burn two different states of fuel at the same time. In particular, it is not possible to burn a liquid fuel and a gaseous fuel at the same time. [0003] On the other hand, the applicant disclosed in CN103691459A a direct combustion method of hydrogen obtained by steam cracking. In this application, the applicant discovered a catalyst capable of cracking steam, and designed a direct combustion steam cracking method. The process of obtaining hydrogen greatly saves energy, reduces costs and redu...
