Description
One, technical field
The utility model relates to burner, a kind of all mixed energy-saving ceramic burner that double jet for gas is arranged of particularly using on the blast funnace hot blast stove.
Two, background technology
Burner is the equipment that hot-blast stove must be used, its quality quality directly affects service life, production efficiency and the product quality of hot-blast stove, along with development of science and technology, the burner that uses mostly is ceramic burner at present, but because structural problem, all there is following situation in present various ceramic burners:
(1) mixing of coal gas and combustion air is relatively poor, and excess air is bigger, and the not CO of combustion is arranged in the waste gas, the raising of excess air and uncombusted CO content has reduced the theoretical temperature combustion of fuel, influences the raising of hot-blast stove dome temperature and hot blast temperature, waste energy contaminated environment;
(2) the medium composition distribution is serious uneven, has reduced efficiency of combustion and ignition temperature, and liner is damaged because of the inequality of being heated, and reduces the result of use and the life-span of burner;
(3) combustion flame produces " vibration ", and when especially using the bigger excess air coefficient of high heating value gas and employing, " vibration " easier generation has a strong impact on service life of hot-blast stove.
Though existing have a kind of burner (application number 200520032014.8) that the problems referred to above are overcome to some extent, in use gas mixes and still has inequality, gas-fired not cmpletely, energy waste is big, vault is hit greatly, lack service life.
Three, utility model content
At above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of all mixed energy-saving ceramic burner that double jet for gas is arranged, the gas that effectively solves in the burner use mixes uneven, combustion efficiency is poor, waste energy and short problem in service life, the technical scheme of its solution is, existing ceramic burner (application number is 200520032014.8) is structurally improved, make it include burner body, air inlet pipe and coal gas inlet pipe, free compression ring road and coal gas circuit are arranged in the body of wall of burner body, the coal gas circuit places above the air circuit, air inlet pipe on the burner body outside joins with the air circuit, the coal gas inlet pipe is connected with the coal gas circuit, being equipped with on the air circuit and turning back upwards that the air of axioversion distributes pipe, air distributes pipe and is contained on the burner body inwall, spout is connected towards the air nozzle of combustion chamber, the coal gas of axioversion of turning back upwards being housed respectively on the coal gas circuit to be distributed pipe and distributes pipe with vertical coal gas, the coal gas that tilts distributes pipe and is contained on the burner body inwall, spout is connected towards second jet for gas of combustion chamber, vertical coal gas distributes pipe and is contained on the burner body inwall, spout is connected towards first jet for gas of combustion chamber, first jet for gas and air nozzle are staggered to be arranged in parallel at grade, first jet for gas places on the same plane of the second jet for gas bottom, constitute double jet for gas structure, the utility model novel structure, unique, rational in infrastructure, gas mixes, sufficient combustion, energy-conservation, long service life, non-environmental-pollution, economic and social benefit is remarkable.
Four, description of drawings
Fig. 1 is a structural profile front view of the present utility model.
Fig. 2 is structural section figure of the present utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
By Fig. 1, shown in Figure 2, the utility model includes burner body, air inlet pipe and coal gas inlet pipe, free compression ring road 8 and coal gas circuit 7 are arranged in the body of wall of burner body, coal gas circuit 7 places above the air circuit 8, air inlet pipe 4 on the burner body outside joins with air circuit 8, coal gas inlet pipe 1 is connected with coal gas circuit 7, being equipped with on the air circuit 8 and turning back upwards that the air of axioversion distributes pipe 3, air distributes pipe 3 and is contained on the burner body inwall, spout is connected towards the air nozzle 6 of combustion chamber, the coal gas of axioversion of turning back upwards being housed respectively on the coal gas circuit 7 to be distributed pipe 2 and distributes pipe with vertical coal gas, the coal gas that tilts distributes pipe 2 and is contained on the burner body inwall, spout is connected towards the second jet for gas 5-2 of combustion chamber, vertical coal gas distributes pipe and is contained on the burner body inwall, spout is connected towards the first jet for gas 5-1 of combustion chamber, the first jet for gas 5-1 and air nozzle 6 staggered being arranged in parallel at grade, the first jet for gas 5-1 places on the same plane of the second jet for gas 5-2 bottom, constitutes double jet for gas structure.
In order to guarantee result of use, said air circuit and coal gas circuit are in this walling of ceramic burner up and down on the same plane; The air of said air circuit 8 tops through turning back into zigzag distributes pipe 3 and is connected with air nozzle 6; Said coal gas circuit 7 bottoms are connected with the first jet for gas 5-1 through distributing pipe 2 with the vertical coal gas of coal gas circuit, and the second jet for gas 5-2 above the same plane of the first jet for gas 5-1 is connected with coal gas circuit 7 middle and upper parts; The first jet for gas 5-1, the second jet for gas 5-2 and air nozzle 6 all are the radiation of rotary-cut shape and place on the burner body inwall; Said coal gas circuit 7 and air circuit 8 are circular or square cavity ring-type.
