Abstract
The utility model relates to a ceramic burner with a vertical upward mixture gas nozzle, which effectively solves the problems that the mixture of the air and the coal gas is not uniform and the coal does not burn completely and the heat accumulation effect is bad. The ceramic burner comprises a wall body, a coal gas pre-heating endless track and a combustion-supporting air pre-heating endless track and an inlet, wherein the combustion-supporting air pre-heating endless track is communicated with the air inlet on the wall and the coal gas pre-heating endless track is communicated with the coal gas inlet on the wall; the combustion-supporting air pre-heating endless track and the coal gas pre-heating endless track are vertical arranged on a same annular surface in the wall body and a coal gas jet tube is vertically arranged on the upper part of the coal gas pre-heating endless track and an air jet tube communicated with the coal gas jet tube is inclinedly arranged on the upper part of the combustion-supporting endless track; the coal gas jet tube and the air jet tube are communicated with the mixture gas tube of the mixture gas nozzle to form a mixture gas vertical upwards spraying structure. The ceramic burner has features of simple, novel and special structure, uniform mixture of the coal gas and the air, complete burning, high heat energy utilization rate, no environmental pollution, saved energy source and obvious economic and social benefit.
Description
One, technical field
The utility model relates to burner, particularly a kind of gaseous mixture nozzle ceramic burner vertically upward.

Fig. 2 be among Fig. 1 A-A to the cross-section structure vertical view.
Five, the specific embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is elaborated.
By Fig. 1, shown in 2, the utility model includes body of wall, gas preheating circuit and combustion air preheating circuit and import thereof, combustion air preheating circuit 4 is connected with air intlet 8 on the body of wall 1, gas preheating circuit 2 is connected with gas inlet 7 on the body of wall 1, combustion air preheating circuit 4 and gas preheating circuit 2 are presented down and are placed on the interior same ring surface of body of wall, gas preheating circuit 2 upper vertical are equipped with gas-jet tube 3, combustion air preheating circuit 4 tops are the oblique air lance 6 that is connected with gas-jet tube 3 that is equipped with, gas-jet tube 3 is connected with the mixture pipe 5 of air lance 6 with gaseous mixture nozzle 10, constitutes gaseous mixture and vertically goes up the spray structure.
In order to guarantee result of use, said body of wall 1 inwall has refractory masses 9; Said gaseous mixture nozzle 10 is rectangle or a circle vertically upward; The inlet of said gas preheating circuit 2 and combustion air preheating circuit 4 is the tangent-type import; Said gas-jet tube 3 and air lance 6 be connected with mixture pipe 5 place angle be 30 °-60 °; Said gas preheating circuit 2 and combustion air preheating circuit 4 are circular or square circuit.
Can be found out by said structure, the utility model is owing to adopted vertical coal gas and the mixed upper spray structure of air, combustion air and coal gas mix, jet power is strong, has effectively guaranteed to have improved degree of combustion by burning condition, improved the utilization rate of ceramic burner heat storage, sufficient combustion has prevented environmental pollution, and the utility model is compared with existing ceramic burner has following significant advantage:
1, coal gas, combustion air vertically upward spray after mixing, and by means of high temperature gases recirculating it are carried out high temperature preheating in hot-blast stove, reach sufficient combustion, ignition temperature height, the purpose that the heat load adjustment scope is big;
2, coal gas, combustion air vertically upward spray after-combustion, turn back under the effect of hot-blast stove vault, the downward thermal current that formation temperature and speed all are evenly distributed then enters the top of hot-blast stove heat storage, thereby heat storage is heated evenly, can reaches the high and stable requirement of hot blast of hot blast temperature;
3, the air inlet pipe of gas preheating circuit and combustion air preheating circuit is tangential the access, make and evenly can obtain mean error less than ± 5% VELOCITY DISTRIBUTION in staggered tens outlets of layout separately, mix thereby improve circumferential air-flow, improve the integral combustion effect;
4, because the utility model has been realized overall uniform burning and diabatic process, and the heat storage of the used hot-blast stove of the comparable co-content blast furnace of the height of its heat storage can reduce by 20%, has effectively saved the energy and investment, economic and social benefit is remarkable.
