Description
Technical field
The utility model relates to burner technical field, is specifically related to a kind of reverberatory furnace burner.
Background technology
Along with more and more higher to energy-conservation and environmental requirement of China, natural gas Pure Oxygen Combustion Technology has obtained application and has promoted at aspects such as reverberatory smelting lead-acid accumulator, plumbous scum silica frost, tin slags.Reverberatory furnace for the above-mentioned assorted material of melting has a common ground, and burner hearth is lower, and burner hearth horizontal cross-section is the rectangle with certain length-width ratio.When melting, require flame broad covered area as much as possible, smelting temperature is wanted evenly, as much as possible little to the damage of burner hearth vault.
Traditional reflective stove natural gas pure oxygen burning burner is two concentric pipes, and inner tube is led to natural gas, and outer tube leads to oxygen, and its burner ejecting head is circular, and making combustion flame is column, can not cover whole burner hearth comprehensively, so the non-uniform temperature in burner hearth; And its flame high temperature dot is to be distributed in surrounding, do not concentrate on completely on furnace charge, cause the utilization rate of part of fuel not high; When melting, the temperature in burner hearth is generally more than 1200 degrees Celsius, and flame temperature is high, because high temperature dot is distributed in surrounding, certainly will have part high temperature dot to be distributed in burner hearth vault region, thereby affect the service life of burner hearth vault.
Utility model content
For above-mentioned technical problem, the utility model aims to provide a kind of burner of applicable reverberatory smelting, and this burner combustion flame is flat, broad covered area, and fuel availability is high, and little to the infringement of burner hearth vault.
The technical scheme that the utility model is dealt with problems is: a kind of reverberatory furnace burner, comprise natural gas supervisor, natural gas supervisor front end is connected with band reducing ejecting head, this band reducing ejecting head comprises ejecting head body and reducing, ejecting head body is that A end face sectional area is greater than B end face sectional area, and the diffusion type semi-closed structure of boring, A end face open, on B end face, have the connector being connected with natural gas supervisor front end, described reducing cross section is rectangle, be fixedly connected with ejecting head body A end face, ejecting head body and reducing are structure as a whole; This band reducing ejecting head is positioned at oxygen distributor chamber, described oxygen distributor chamber is an enclosed cavity being connected with burner hearth, between oxygen distributor chamber and burner hearth, be provided with dividing plate, baffle surface is distributed with oxygen squit hole, on dividing plate, be also provided with and the installing hole matching with reducing ejecting head, band reducing ejecting head is fixedly mounted in installing hole, and outlet top edge and the top edge fixed seal connection of installing hole with reducing ejecting head, exports between lower limb and both sides of the edge and dividing plate and leaves gap.
In technique scheme, for making ejecting head body construction reliable and stable, manufacturing process is simple, and described ejecting head body is hollow axial symmetry truncated rectangular pyramids structure, and truncated rectangular pyramids A end face open has the connector being connected with natural gas supervisor front end on B end face.
For making oxygen can enter more uniformly oxygen distributor chamber, described oxygen distributor chamber rear end is connected with the oxygen endless tube with arm, and described oxygen endless tube is an annular pipeline, and bottom is provided with oxygen intake, and natural gas supervisor is through the ring heart of oxygen endless tube; Described arm one end is connected to the side surface of oxygen endless tube, and the other end is arranged on oxygen distributor chamber rear end.
In technique scheme, for making oxygen more be distributed in burner hearth below, while more impelling burning, down, described oxygen squit hole distributes sparse flame high temperature dot at dividing plate upside, and downside is densely distributed.
In technique scheme, ejecting head body and reducing can have multiple connected mode, for example, weld or directly adopt integrated mode to be processed to form integral structure, ensure in principle the junction sealing of ejecting head body and reducing.More reliable for making in this band reducing ejecting head use procedure, and longer service life, be preferably integrative-structure.
When melting, natural gas enters into band reducing ejecting head from natural gas supervisor, simultaneously, oxygen enters from oxygen endless tube, flow into oxygen distributor chamber through arm, in oxygen distributor chamber, be further evenly distributed, then most of oxygen flows out from gap, mix and burn with natural gas, small part oxygen flows out and natural gas mixed combustion from the oxygen squit hole of dividing plate.
Remarkable result of the present utility model is:
1. owing to having designed ejecting head body and the square-section band reducing ejecting head of diffusion type, natural gas is from natural gas supervisor ejection, be not that straight line enters burner hearth, but at ejecting head body through diffusion, the gas and the oxygen mix that form larger cross section are burnt, while making to burn, flame is flat, flame broad covered area, even if traditional burner can not reach the corner of temperature requirement in burner hearth, burner of the present utility model also can make it reach temperature required, and smelting temperature in whole burner hearth is even.
2. owing to leaving gap between the outlet lower limb with reducing ejecting head and both sides of the edge and dividing plate, most of oxygen flows out with natural gas and mixes from gap, while making to burn, flame high temperature dot down, flame high temperature dot is concentrated on furnace charge, more be conducive to the melting of furnace charge, just improved accordingly fuel availability; Meanwhile, because high temperature dot is down, so the just corresponding temperature of burner hearth vault is lower, its longer service life.
3. the design of oxygen distributor chamber and oxygen endless tube, can mix according to required ejection mode oxygen with natural gas, burning is more abundant and flame profile is better.
