Description
Technical field
The utility model belongs to top blast stove smelting technique apparatus field, is specifically related to a kind of top blast stove burner for subsequent use.
Background technology
In top blast stove smelting technique, burner for subsequent use is key equipment, is mainly used in baker and thermal insulation furnace body.The low temperature baker stage according to baker heating curve to the operation of top blast bake oven stove, need be deposited in furnace bottom heating by ignition to 400 DEG C in the baker first stage with timber, and this temperature one day, rear insertion burner for subsequent use continued baker and heats up.Because combustion of wood calorific capacity is low, a large amount of timber bakers need be consumed; Under top blast stove changes rifle or other blowing out situations aborning, then with little oil mass thermal insulation furnace body within 2 hours, within more than 2 hours, then use large oil mass thermal insulation furnace body, existing burner technology over-emitting black exhaust during little oil mass, flame easily extinguishes.Existing burner technology, tubing diameter 100mm, insufficient pressure during little oil mass, rifle head outlet pressure is little, diesel oil atomization weak effect, can not be suitable for thermal insulation furnace body and the baker stage needs different oil masses and the change of temperature.
3 straight holes of the rifle head setting of prior art, what this patent was arranged is 4 inclined holes.Such design, when rifle head is fuel-displaced in the shape of a spiral, easily forms blue longer flame and covers furnace bottom position.
Utility model content
For solving above technology Problems existing, the utility model provides a kind of and reduces combustion of wood, and grease gun igniting is convenient, the burner for subsequent use of the top blast stove low temperature baker that oil inflame is effective and soak.
Its technical scheme is:
A kind of top blast stove burner for subsequent use, comprise large oil gun, large oil gun fuel tap, small oil gun, small oil gun fuel tap, oil circuit, combustion-supporting airduct and combustion-supporting air compartment, described oil circuit one end is provided with large oil gun and small oil gun, large oil gun and small oil gun end extend to combustion air chamber interior, large oil gun is provided with large oil gun fuel tap, small oil gun is provided with small oil gun fuel tap, combustion-supporting air compartment side is provided with combustion-supporting airduct.
Close large oil gun fuel tap, open small oil gun fuel tap, during baker, first use small oil gun, insert burner hearth with after torch point burner, by baker heating curve variations in temperature operation oil mass; When needs temperature is more than 800 DEG C, then switched by DCS Long-distance Control, close small oil gun fuel tap, open large oil gun fuel tap, the switching of small oil gun to large oil gun can be realized, be applicable to soak body of heater.Such design, small oil gun is applicable to low temperature baker, decrease low temperature baker stage use amount of wood, avoid a large amount of firewood baker and not good problem of Baker effect of using, the large small oil gun of burner switches can realize DCS Long-distance Control, simple to operate, flexible adjustment, fire box temperature as required can select large and small oil gun thermal insulation furnace body, enhance productivity.Small oil gun atomizing effect is good, igniting easily, potential safety hazard when decreasing igniting.
Further, the rifle head of small oil gun is provided with 4 inclined holes, and 4 inclined holes are in arrangement clockwise.
Accompanying drawing explanation
Fig. 1 is top blast stove nozzle structure schematic diagram for subsequent use;
Wherein, the large oil gun of 1-, the large oil gun fuel tap of 2-, 3-small oil gun, 4-small oil gun fuel tap, 5-oil circuit, the combustion-supporting airduct of 6-, the combustion-supporting air compartment of 7-.
Detailed description of the invention
As shown in Figure 1, a kind of top blast stove burner for subsequent use, comprise large oil gun 1, large oil gun fuel tap 2, small oil gun 3, small oil gun fuel tap 4, oil circuit 5, combustion-supporting airduct 6 and combustion-supporting air compartment 7, described oil circuit 5 one end is provided with large oil gun 1 and small oil gun 3, it is inner that large oil gun 1 and small oil gun 3 end extend to combustion-supporting air compartment 7, large oil gun 1 is provided with large oil gun fuel tap 2, small oil gun 3 is provided with small oil gun fuel tap 4, combustion-supporting air compartment 7 side is provided with combustion-supporting airduct 6.The rifle head of small oil gun is provided with 4 inclined holes, and 4 inclined holes are in arrangement clockwise, and combustion-supporting air compartment 7 side is provided with combustion-supporting airduct 6.
The small oil gun installed additional, tubing diameter 40mm, selects the rifle head of 4 inclined holes, pressure is large, atomizing effect good, igniting is easy, is suitable for oil mass 80 ~ 300kg/h, and when realizing low temperature baker, fire box temperature controls 200 ~ 800 DEG C of changes, replacement timber low temperature baker.In 800 ~ 1250 DEG C of muffle kiln stages, be switched to large oil gun by DCS remote control technology, large oil gun is suitable for oil mass 300 ~ 600kg/h, can realize the variations in temperature that fire box temperature controls at 800 ~ 1250 DEG C.
Sharing with oil and combustion air and large oil gun of small oil gun, the rifle achieving burner is dual-purpose, and namely baker cold stage selects small oil gun, and hot stage DCS controls to be switched to large oil gun.
