In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
Top ignition dicyclo road overheavy firing ceramic burner, comprise air intake, gas entry, air circuit, coal gas circuit, gas passage, premixer, premixed combustion nozzle and combustion chamber, described air intake is connected with air circuit, described gas entry is connected with coal gas circuit, described air circuit is through air rising passway access premixer, coal gas circuit accesses premixer through gas passage, and premixer is connected with combustion chamber through premixed combustion nozzle; Described air circuit and coal gas circuit are provided with water conservancy diversion brick (ensureing the uniformity of spout); Air circuit, coal gas circuit are that inner and outer ring is arranged, coal gas circuit outside, air circuit interior, or air circuit outside, coal gas circuit is interior.
By such scheme, described gas passage is boss structure.
By such scheme, described chamber cavity is also equipped with overfire air jet.
By such scheme, described premixed combustion nozzle is along just arranging a row of horizontal of axis, combustion chamber.
Contrast other top combustion burners, beneficial effect of the present utility model is:
(1) unique air circuit, coal gas circuit and water conservancy diversion brick
The utility model is provided with inside and outside two gas circuit, and be respectively air circuit, coal gas circuit, air circuit is positioned at coal gas circuit, and two gas circuit are equipped with water conservancy diversion brick, to make outlet channel gas more even.Air circuit, coal gas circuit are inside and outside arranges that compact and reasonable reduces height;
(2) self-preheating, cooling
Special construction of the present utility model makes it have self-preheating and refrigerating function: cryogen (air, coal gas) reduces the temperature of refractory masonry on the one hand, effectively can improve the service life of burner; On the other hand, high temperature masonry carries out preheating to cryogen, effectively can improve the theoretical temperature combustion of coal gas under the same conditions;
(3) thermal property more excellent, have more safety guarantee
The utility model coal gas and air are through gas passage in its respective circuit, and enter premixer's mixing, gas passage is designed to boss structure, to prevent coal gas tempering; Under the pressure effect of coal gas ejection air-flow and the air-flow of air own, both carry out mandatory abundant premixed in premixer, then spray into chamber cavity by premixed combustion nozzle and burn, and form flue gas stream from top to bottom.At chamber cavity, continue to be furnished with Secondary Air and enter chamber cavity by overfire air jet, thus improve ignition temperature, realize flameless combustion, eliminate combustion pulsation; Resistance is damaged little, and burning load adjustable range is large, furnace pressure fluctuation is little, and working stability is reliable, thus improves lifetime of hot-air stove, makes hot-blast stove have more safety guarantee;
(4) overheavy firing, improves burning capacity, efficiency, saves the energy, reduces combustion product gases pollutant index
The utility model strengthening premixed combustion, first premix is carried out before air, coal gas mixed combustion, and be furnished with secondary air combustion aid, even if make when coefficient of excess air less (1.05), also coal gas can be made to burn completely, thus not only improve burning capacity and efficiency, more save fuel, reduce pollutant index in gas-fired flue gas, for the reasonable dedusting of burnt gas and discharge provide prerequisite guarantee; This function is just to the horizontal premixed combustion nozzle of axis, combustion chamber by a row, the air-flow of ejection collides mutually at nozzle cross-section center, forms downward stream stock, at middle part in decline process, formed with secondary combustion-supporting air and mix, strengthen burning, and air-flow forms recirculating zone around Inner Wall of Combustion Chamber, center stream plume speed is higher, after entering the vault expansion segment outside burner, center stream stock speed sharply reduces, and spreads towards periphery, to such an extent as to reaches unanimity when flue gas arrives checker brick top.

Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and detailed description of the invention of the present utility model is described.
Top ignition dicyclo road overheavy firing ceramic burner described in the utility model, based under national energy environmental protection policy background, industrial resources utilizes on basis, in conjunction with hot-blast stove technology theory and burner combustion theory, by more than ten years hot blast stove design, premised on application and summary of experience under to complete, be applied particularly to top combustion stove, as shown in Figure 1, its structure as shown in Figure 2.This burner is provided with air intake 001, gas entry 002, air circuit 003, coal gas circuit 004, water conservancy diversion brick 005, air rising passway 006, gas passage 007, premixer 008, premixed combustion nozzle 009, overfire air jet 010 and combustion chamber 011.Air intake 001 is connected with air circuit 003, described gas entry 002 is connected with coal gas circuit 004, air circuit 003 accesses premixer 008 through air rising passway 006, coal gas circuit 004 accesses premixer 008 through gas passage 007, and premixer 008 is connected with combustion chamber 011 through premixed combustion nozzle 009; Described air circuit 003 and coal gas circuit 004 are provided with water conservancy diversion brick 005 (ensureing the uniformity of spout); Air circuit 003, coal gas circuit 004 be inner and outer ring arrange, coal gas circuit 004 outside, air circuit 003 interior, or air circuit 003 outside, coal gas circuit 004 interior, compact and reasonable, reduce height.
Gas passage 007, in boss structure, prevents coal gas tempering; Under the pressure effect of coal gas ejection air-flow and the air-flow of air own, both carry out mandatory abundant premixed in premixer, then spray into combustion chamber 011 cavity by premixed combustion nozzle 009 and burn, and form flue gas stream from top to bottom.
Combustion chamber 011 cavity is also equipped with overfire air jet 010 (also can cancel the setting of overfire air jet 010), Secondary Air enters combustion chamber 011 cavity by overfire air jet 010, thus raising ignition temperature, realize flameless combustion, eliminate combustion pulsation; Resistance is damaged little, and burning load adjustable range is large.
By a row just to the horizontal premixed combustion nozzle 009 of axis, combustion chamber 022, the air-flow of ejection collides mutually at nozzle cross-section center, downward stream stock is formed at middle part, in decline process, formed with secondary combustion-supporting air and mix, strengthen burning, and air-flow forms recirculating zone in combustion chamber 011 periphery of inner wall, center stream plume speed is higher, after entering the vault expansion segment outside combustion chamber 011, center stream stock speed sharply reduces, and spread towards periphery, to such an extent as to reach unanimity during flue gas arrival checker brick top, even if make when coefficient of excess air less (1.05), also coal gas can be made to burn completely.
Above-describedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalence change that the utility model claim is done, still belong to protection domain of the present utility model.
