Description
Technical field
The present invention relates to coke oven technical field more particularly to a kind of structures for reducing coke oven combustion chamber burner heat dissipation capacity.
Background technique
Coke oven has the characteristics that energy consumption is high, pollution is big as main coking equipment.Coke oven belongs to high temperature kiln, surface
Heat dissipation capacity is high one of the reason of its energy consumption greatly.Raising with country to environmental requirement, the energy-saving problem of coke oven is increasingly
It is prominent.
Coke oven is generally by the ancillary equipments group such as regenerative chamber, chute, combustion chamber, furnace roof and other foundations of civil work, furnace retaining ironware
At.Combustion chamber is the highest position of coke oven temperature, and the temperature in the flue of combustion chamber can generally reach 1300-1400 DEG C.Now
The burner of capacity coke oven combustion chamber generally forms (such as Granted publication by silica brick and the good high alumina brick masonry of heat impact strength
Number for CN2892859Y Chinese patent disclosed in " coke oven combustion chamber-carbonization chamber unit cokery side furnace head structure "), burner build
External side is provided with the furnace retaining ironware being made of protection board, firedoor frame and furnace stay etc..
Currently, mutually string leakage between adjacent two carbonization chamber in order to prevent, guarantees the leakproofness of coke oven, the guarantor in furnace retaining ironware
Backplate is frequently with big protection board structure.In the baker later period, with silicon fire in the gap between big protection board and burner masonry (refractory brick)
Mud is in the milk, and guarantees leakproofness.But due to forming silica brick, high-alumina brick and the ganister of burner masonry, furnace retaining ironware is led
Hot property is preferable, cause combustion chamber machine/coke side burner heat dissipation capacity it is bigger (account for 60% or so of coke oven surface radiating total amount,
The temperature of the furnace retainings ironware such as protection board is up to 300 DEG C or more), greatly reduce the service life of furnace retaining ironware；And it pushes away
Operating ambient temperature locating for worker is high when burnt, and environment is poor.In addition, the heat dissipation of combustion chamber burner is mainly the stream of side quirk heat
It loses, causes side flue temperature 150-300 DEG C lower than intermediate fire path temperature, green coke occurs in burner, and smoldering, which occurs, in when coke pushing burns with anger
The phenomenon that；The maturation that burner coke is waited when production, can extend coking time accordingly, increase energy consumption.
Summary of the invention
The present invention provides a kind of structure for reducing coke oven combustion chamber burner heat dissipation capacity, big protection board and burner masonry it
Between setting have heat preservation and insulation cast bed of material, guarantee coke oven leakproofness while, can be effectively reduced side quirk dissipate
Heat improves the temperature of side quirk and the service life of furnace retaining ironware, reaches mesh that is energy-saving, improving energy utilization rate
's.
In order to achieve the above object, the present invention is implemented with the following technical solutions:
The burner masonry outside of a kind of structure reducing coke oven combustion chamber burner heat dissipation capacity, coke oven combustion chamber sets furnace retaining iron
Part, furnace retaining ironware include big protection board, firedoor frame and furnace stay；It is poured between the big protection board and burner masonry equipped with insulating refractory
The mixing cast bed of material of castable refractory and heat insulating casting material is equipped between material feeding layer, or big protection board and burner masonry.
Asbestos-free calcium silicate board is filled in the inboard groove of the big protection board.
The asbestos-free calcium silicate board is pasted onto the groove on the inside of big protection board by building adhesive.
The inside of the big protection board is equipped with multiple anchoring pieces.
The top of the burner masonry is equipped with grout hole.
The burner masonry uses double-layer structure, and interior burner is built using silica brick in double-layer structure, and outer burner is divided into furnace shoulder
With intermediate position, high alumina brick masonry is wherein used at furnace shoulder, intermediate position uses fire resisting brick masonry.
The refractory brick is insulating brick or floating bead brick.
Compared with prior art, the beneficial effects of the present invention are:
1) cast bed of material of the setting with heat preservation and insulation between big protection board and burner masonry guarantees coke oven sealing
Property while, reduce combustion chamber burner heat dissipation capacity；
2) when furnace retaining ironware applies protection protection to burner outside combustion chamber, protection point of force application uses high alumina at furnace shoulder
Brick is not that the intermediate position of stress point uses the refractory brick with heat insulation function, as insulating brick, floating bead brick or other lightweights are viscous
Cob brick；The heat dissipation of side quirk is advantageously reduced, the temperature of side quirk is improved；
3) temperature that can effectively improve side quirk is conducive to the maturation of burner coke, shortens coking time, when preventing coke pushing
There is phenomenon of burning with anger of smoldering；
4) it can reduce the operating temperature of furnace retaining ironware, improve the service life of furnace retaining ironware；
5) it is not only suitable for newly-built coke oven, is also applied for the transformation of old coke oven；Realize energy-saving, increase energy utilization rate
Purpose.
