Abstract
The utility model relates to a metal burner used for the reforming furnace, comprising a metal shell and an oxygen hose. The metal shell is equipped with a jacket and the oxygen hose is positioned on the central axis of the shell. The tip of the shell is equipped with the jet orifice; the upper part of the oxygen hose is connected to the oxygen intake, while the lower end thereof is positioned at the jet orifice of the shell. The ring-type vapor cavity is arranged between the shell and the oxygen hose as well as connected to the steam in which is situated at the upper part of the shell. The cooling water inlet is arranged at the upper part of the shell and connected to the jacket which is between the cooling water outlet and the metal shell. The burner adopts the all-metal construction and arranged at the middle position of the reforming furnace end, so that the oxygen is directly sprayed into the raw gas. The flame does not contact the inner lining of the reforming furnace. Therefore, the furnace inner lining will not be burned out. Thus, long-time operation of the reforming furnace can be guaranteed, so as to improve the economic efficiency of the virgin gas-made synthetic ammonia and the methanol. So, this utility model is applicable to the oven gas reforming furnace and the natural gas secondary reformer.
Description
Technical field
The utility model relates to the converter in industrial synthetic ammonia and the synthesizing methanol device, particularly relates to the furnace head burner in the converter, and this burner provides heat for the conversion of methane in the unstripped gas.
Background technology
Converter is the visual plant in the chemical plant installationss such as coke(oven)gas synthetic ammonia and synthesizing methanol.Enter the converter burner after being preheated from the unstripped gas of purification section, oxygen enters burner after preheating, in burner, burn, behind the gas thorough mixing after the burning, enter in the conversion catalyst of splendid attire in the converter body of heater and carry out conversion reaction, reforming gas through conversion reaction is discharged converter, removes synthetic ammonia or methyl alcohol, CH in the reforming gas of this moment
4Content is less than 0.5%.
The industrial converter furnace head burner that is used for the coke(oven)gas methane conversion is still extensively continued to use traditional nonmetal burner now, and this burner adopts the non-metallic material corundum to build by laying bricks or stones, therefore masonry quality is had strict requirement.Yet build by laying bricks or stones in the operation actual, be difficult to guarantee the masonry quality of burner, building by laying bricks or stones under the not full situation of mortar, may produce oxygen in the use with coke(oven)gas in burner brickwork joint place seepage, the phenomenon of abnormal combustion takes place, thereby cause the fusing of corundum overtemperature, burn out the accident of burner liner.
Summary of the invention
The purpose of this utility model provides a kind of converter metal burning device, and is short power lifetime to solve the nonmetal burner of converter, burns out the problem of burner liner easily.
Converter of the present utility model is made up of metal shell that has chuck and the oxygen hose that is positioned on the housing central axial line with the metal burning device, and the housing end is provided with spray orifice, and the oxygen hose upper end connects oxygen intake, and the lower end is positioned at the spray orifice position of housing.Ring-type steam cavity between housing and the oxygen hose is communicated with the vapour inlet that is positioned at the housing upper end, and the cooling water inlet and the cooling water outlet that are arranged on housing top are communicated with the chuck of metal shell.
Burner of the present utility model is divided into three-decker, and its innermost layer is the oxygen hose that is used for oxygen is sprayed into unstripped gas, and oxygen is entered in the oxygen hose by oxygen intake, sprays into the unstripped gas from the spray orifice of burner head.In the ring-type steam cavity of oxygen hose outside, feed protection steam; protection steam enters burner by vapour inlet; also from spray orifice ejection burner; mainly play two kinds of effects: 1) when oxygen sprays, can play effect temporary transient and that coke(oven)gas is isolated; make flame in the burning of the head of burner, play the effect of protection burner, 2) form in the middle of the sealing coat of oxygen and outer water coolant; avoid water coolant reduction oxygen temperature in the outer chuck, influence the burning of coke(oven)gas.Feed water coolant in the outermost metal shell chuck; water coolant is flowed into by the cooling water inlet, flows out from cooling water outlet, by the good cooling of water coolant; can reduce the surface temperature of metal burning device, with of the atmosphere midium or long term stable operation of protection burner at 1600 ℃.
Burner of the present utility model is the all-metal construction burner, be arranged on the mid-way of converter burner, directly will burn and spray in the unstripped gas with oxygen, flame does not contact with the converter liner, can not burn out inner lining of furnace, guarantee the long-term operation of converter, improved the economic benefit of unstripped gas system synthetic ammonia, synthesizing methanol.
Burner of the present utility model is applicable to that coke(oven)gas converter, Sweet natural gas secondary reformer are suitable for.
Description of drawings
Fig. 1 is the structural representation of the utility model converter with the metal burning device.
Embodiment
Converter of the present utility model is made up of metal shell 4 and the oxygen hose 7 that is positioned on housing 4 central axial lines with metal burning device structure as shown in Figure 1.
Housing 4 has chuck 5, can feed water coolant in the chuck 5, and water coolant is entered by the cooling water inlet 3 that is arranged on housing 4 tops, flows out from the cooling water outlet 9 that is arranged on housing 4 tops equally.Be provided with spray orifice 8 in the end of housing 4.
The upper end of oxygen hose 7 is connected with oxygen intake 1, and the lower end is positioned at spray orifice 8 positions of housing 4, after oxygen is entered by oxygen intake 1, from spray orifice 8 incoming stock gas.
Constitute a cyclic steam cavity 6 between housing 4 and the oxygen hose 7, the upper end of steam cavity 6 is communicated with the vapour inlet 2 that is positioned at housing 4 upper ends, and the lower end outlet is arranged on spray orifice 8 places equally, is connected with the protection steam in the steam cavity 6.
