Problems solved by technology

[0002] Conventional burners use blast furnace gas with high calorific value and oxygen mixture to burn, and the flame obtained is relatively stable, but if the conventional burner uses blast furnace gas with low calorific value for combustion, the flame obtained will be too low due to the low calorific value of blast furnace gas. But it is easy to extinguish. After the flame is extinguished, the concentration of blast furnace gas at the outlet of the burner will increase. At this time, if you touch the burner again, it will easily explode

Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0011] Such as figure 1 As shown, the low calorific value blast furnace gas composite burner includes: a first delivery pipe 1 for transporting low calorific value blast furnace gas, a second delivery pipe 2 for oxygen delivery, and the second delivery pipe 2 is installed in the first delivery pipe 1, at the outlet of the first conveying pipe 1, a flame stabilizing plate 11 for guiding blast furnace gas is provided, and the flame stabilizing plate 11 is located inside the outlet end of the first conveying pipe 1, so that the first conveying pipe 1 The outlet and the flame-stabilizing disc 11 can surround a mixed combustion chamber 12, and an oxygen nozzle 13 with an outlet facing outward is pierced at the center of the flame-stabilizing disc 11, and the outlet of the second delivery pipe 2 communicates with the oxygen nozzle 13. Oxygen w...

Abstract

The invention discloses a composite burner of low heating value blast furnace gas. The composite burner of the low heating value blast furnace gas comprises a first conveying pipe used for conveying the low heating value blast furnace gas and a second conveying pipe used for conveying oxygen. The second conveying pipe is arranged in the first conveying pipe in a penetrating through mode, and a flame stabilizing plate is arranged at an outlet of the first conveying pipe. The outlet of the first conveying pipe and the flame stabilizing plate can enclose a mixed combustion chamber, an oxygen spray nozzle is arranged at the center of the flame stabilizing plate, and an outlet of the second conveying pipe communicates with the oxygen spray nozzle. A third conveying pipe used for delivering airis arranged in the second conveying pipe, a fourth conveying pipe used for conveying natural gas is arranged in the third conveying pipe, an ignition through hole is formed in the center of the oxygenspray nozzle, and a natural gas spray nozzle communicating with an outlet of the fourth conveying pipe is arranged in the ignition through hole. The composite burner of the low heating value blast furnace gas can adopt the natural gas which always combusts at the center to light the low heating value blast furnace gas all the time, and thus the low heating value blast furnace gas can keep combustion all the time, and safety hazards are greatly reduced.

Description

technical field [0001] The invention relates to the field of combustion equipment, in particular to a low calorific value blast furnace gas composite burner. Background technique [0002] Conventional burners use blast furnace gas with high calorific value and oxygen mixture to burn, and the flame obtained is relatively stable, but if the conventional burner uses blast furnace gas with low calorific value for combustion, the flame obtained will be too low due to the low calorific value of blast furnace gas. And easy to extinguish, the blast furnace gas concentration at the outlet of the burner will increase after the flame is extinguished, and at this time, the burner will easily explode if it is touched again. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low calorific value blast furnace gas composite burner which can use the mixture of oxygen and low calorific value blast furnace gas for safe combustion. ...
