Description
Technical field
The present invention relates to coke oven technical field more particularly to a kind of lamp cap bricks in flue, with multistage outlet.
Background technique
Coke oven is made of regenerative chamber, chute, combustion chamber, carbonization chamber and furnace roof etc..Coal gas and air mix in the combustion chamber
Combination burning is transferred heat to the coal in carbonization chamber by way of heat transfer and heat radiation, coal is made to be converted into coke.Coke oven
Thermal regulation includes long to heating temperature and the high adjusting to heating temperature, and uniform coking chamber wall Temperature Distribution not only may be used
To save fuel, coking furnace shaft can also be prevented to be damaged because of hot-spot.Currently, capacity coke oven mostly uses waste gas circulation, more
Duan Jiare, the setting first-class mode of high-low lamp adjust the high to heating uniformity of coke oven.
The coke-stove gas outlet brick of flue bottom is known as lamp cap brick (or burner block).The effect of lamp cap brick is burnt when using
When producer gas heats, guarantees coal gas Reasonable Combustion, make charge of coke height to homogeneous heating.Under normal conditions, the top surface of lamp cap brick and vertical
The bottom surface of quirk is concordant or a little higher than flue bottom surface is known as low lamp cap, and the top surface of lamp cap brick exceeds being known as exhaust gas circulation hole
High burner.And height lamp cap is located at the outlet of heating gas in flue two neighboring in combustion chamber away from carbonization chamber bottom difference
Height at, the top of combustion chamber, lower part heating state can so slightly improved.
Summary of the invention
The present invention provides a kind of lamp cap bricks with multistage outlet, for supplying coke-stove gas to segmentation along flue height
Enter, be conducive to elongate the flame in flue, improves coke oven height to heating uniformity, reduce heating gas consumption and nitrogen oxidation
Object production quantity realizes that the purpose of source energy-saving and emission-reduction, with good economic efficiency and environmental benefit are worthy to be popularized.
In order to achieve the above object, the present invention is implemented with the following technical solutions:
A kind of lamp cap brick with multistage outlet, the lamp cap brick are set to flue bottom, and the bottom of lamp cap brick is equipped with one
A gas entry is connected with the gas pipe on chute area gas pipe brick, and the top of lamp cap brick is equipped at least two gas exit, and each
The height of gas exit is different.
The sectional area of each gas exit is identical or different.
The cross sectional shape of each gas exit is round, ellipse or polygon.
Each gas exit is arranged vertically upwards, the height of bottom gas exit be higher than exhaust gas circulation hole on along height
Degree.
Adjusting brick or plug brick are equipped at each gas exit.
Compared with prior art, the beneficial effects of the present invention are:
1) lamp cap brick structure is simple, is easy to build；
2) it can use, can also be applied in the coke oven of transformation renovation in newly-built coke oven；
3) lamp cap brick is equipped with the different gas exit of multiple height, is conducive to elongate the flame in flue, improves burnt
Furnace height reduces heating gas consumption and formation of nitrogen oxides to heating uniformity, realizes the purpose of source energy-saving and emission-reduction, tool
There are good economic benefit and environmental benefit.

Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing:
As shown in Figure 1 and Figure 2, a kind of lamp cap brick with multistage outlet of the present invention, the lamp cap brick 4 are set to vertical fire
5 bottom of road, the bottom of lamp cap brick 4 are equipped with a gas entry 41 and are connected with the gas pipe on 1 gas pipe brick 7 of chute area, lamp cap
The top of brick 4 is equipped at least two gas exit 42, and the height of each gas exit 42 is different.
The sectional area of each gas exit 42 is identical or different.
The cross sectional shape of each gas exit 42 is round, ellipse or polygon.
Each gas exit 42 is arranged vertically upwards, and the height of bottom gas exit 42 is higher than exhaust gas circulation hole 3
Upper edge height.
Adjusting brick or plug brick are equipped at each gas exit 42.
As shown in figure 3,5 two sides of flue are separated by heating wall 6 with the carbonization chamber being disposed adjacent, the bottom of flue 5
Face is concordant with the bottom surface 2 of carbonization chamber.5 bottom of flue is connected by chute area 1 with regenerative chamber, and the bottom of flue 5 sets exhaust gas
Circulation port 3 and lamp cap brick 4.Of the present invention is a kind of lamp cap brick with multistage outlet, and multiple coal gas on lamp cap brick 4 go out
Mouth 42 is located at different level heights, and the never level gas exit 42 of coal gas mixes with air burning into flue 5.Coal
The multistage of gas, which is fed, to be conducive to elongate the flame in flue 5, is improved coke oven height to heating uniformity, is reduced heating gas consumption
Amount and formation of nitrogen oxides.
The opening size of each gas exit 42 of the lamp cap brick 4 can be adjusted by adjusting brick or be opened with plug brick
It closes.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
