Description
Technical field
The present invention relates to coke oven technical field more particularly to a kind of coke oven combustion chamber furnace head structures of optimization.
Background technique
In coking field, for coke oven as main coking equipment, the outstanding feature run at present is exactly high energy consumption.
As the attention degree that Environmental is protected is higher and higher, the requirement to highly energy-consuming trade is also increasingly stringenter, to respond state
Family's policy considers, coke oven construction also constantly improves to some extent from energy-saving and emission-reduction.
Coke oven is made of the ancillary equipments such as regenerative chamber, chute, combustion chamber, furnace roof and other foundations of civil work, furnace retaining ironware.
As shown in Figure 1 and Figure 2, wherein combustion chamber is generally made of flue 4 14-18, passes through flue partition 3 between each flue 4
Be separated by, each combustion chamber it is adjacent be carbonization chamber.Air and can coal gas burn in the flue 4 of combustion chamber, calory burning
The indoor feed coal of charing is passed to by the partition wall 2 between combustion chamber and carbonization chamber, to keep coal closed in carbonization chamber
Heating, until conversion coke.
As shown in Figure 1 and Figure 2, the furnace head structure (including pusher side burner and coke side burner) of conventional coke oven is usually by thermally conductive
Silica brick and high alumina brick masonry of good performance at double-layer structure, wherein at layer structure furnace shoulder use high alumina brick masonry, internal layer
Structure and layer structure, which remove, is all made of silica brick masonry at furnace shoulder；The outside of burner masonry directly contacts furnace retaining ironware, coke oven production
When indoor temperature of burning can generally reach 1300-1400 DEG C, a large amount of heat can be conducted by furnace head structure distribute, no
But it is unfavorable for the maturation of coke oven end position coke, makes the reduced service life of furnace retaining ironware, while also will increase energy consumption, waste
The a large amount of energy, this is also the major reason that coke oven becomes highly energy-consuming equipment.
Summary of the invention
The present invention provides a kind of coke oven combustion chamber furnace head structures of optimization, multiple heat-insulated by being arranged in burner masonry
Hole greatly reduces the conduction of heat, is conducive to the maturation of burner coke and improves the service life of furnace retaining ironware, while also
Conducive to coke oven energy consumption is reduced, increase the utilization efficiency of the energy.
In order to achieve the above object, the present invention is implemented with the following technical solutions:
A kind of coke oven combustion chamber furnace head structure of optimization, the burner including being formed using the inside and outside double-deck fire resisting brick masonry are built
Body, using occlusion seam connection between 2 layers of refractory brick；It is laterally and/or high multiple heat-insulated to being equipped with along coke oven in the burner masonry
Hole.
The insulation hole subsection setup or elongated setting in burner masonry.
The insulation hole, which is set to, stings commissure, by opening up on upper and lower 2 layers of refractory brick or inside and outside 2 layers of refractory brick corresponding surface
Groove be collectively formed.
The described insulation hole is circular hole, and diameter is
Compared with prior art, the beneficial effects of the present invention are:
1) by the way that multiple insulation holes are arranged in burner masonry, the conduction of heat is greatly reduced, burner coke is conducive to
Maturation and improve furnace retaining ironware service life, while also help reduce coke oven energy consumption, increase the utilization efficiency of the energy；
2) structure is simple, easy for construction, and small investment is quick.

Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing:
As shown in Figure 3, Figure 4, the coke oven combustion chamber furnace head structure of a kind of optimization of the present invention, including using inside and outside double
Using occlusion seam connection between 1,2 layers of refractory brick of burner masonry that layer fire resisting brick masonry is formed；Along coke oven in the burner masonry 1
It is laterally and/or high to equipped with multiple insulation holes 5.
The insulation hole 5 subsection setup or elongated setting in burner masonry 1.
The insulation hole 5, which is set to, stings commissure, by opening on upper and lower 2 layers of refractory brick or inside and outside 2 layers of refractory brick corresponding surface
If groove be collectively formed.
The described insulation hole 5 is circular hole, and diameter is
[embodiment]
In the present embodiment, the furnace head structure of coke oven uses the burner masonry 1 of double-layer structure, wherein at the furnace shoulder of layer structure
Using high alumina brick masonry, the part of endothecium structure and layer structure in addition to furnace shoulder is all made of silica brick masonry.Forming endothecium structure
Silica brick lateral surface along Gao Xiangshe semi-circular recesses, forming the high-alumina brick of layer structure, the medial surface corresponding position edge of silica brick
Gao Xiangshe semi-circular recesses, ectonexine silica brick are connected using occlusion slit formula, after masonry, by the silica brick and outer layer knot of endothecium structure
Circular insulation hole 5 is collectively formed in corresponding semi-circular recesses on the silica brick of structure, and the insulation hole 5 is along height in burner masonry 1
Elongated setting, both ends are closed by furnace bottom and top construction respectively.
In the present embodiment, set respectively in correspondence top surface, the bottom surface of the high-alumina brick and silica brick that form layer structure semicircle recessed
Slot, upper and lower 2 layers between silica brick or high-alumina brick and silica brick using be engaged slit formula connection, burner masonry 1 masonry after, upper and lower 2
Circular insulation hole 5 is collectively formed by corresponding semi-circular recesses between layer silica brick or silica brick and high-alumina brick, the insulation hole 5 is along coke
The setting of furnace transversal sectional, every segment length are respectively less than silica brick or high-alumina brick in the length of corresponding direction.
After furnace head structure of the present invention, the coke maturing rate at coke oven end position rises 5.5%, coke oven entirety energy
The service life of consumption decline 3.2%, furnace retaining ironware extends 4.6%.
