Input cost is lower, service life is long, the position smaller that takes up space and requires heat-exchange device Operation and Maintenance simpler, maintenance cost
Lower device.
Traditional heat-storage type burner is mostly to use dual chamber regenerative chamber, and air and combustion gas are mixed by force in burner mouth,
It is sprayed again from burner.So the temperature at burner oral area is high, the length of flame is short, and Temperature Distribution is not uniform enough.Due to burning
High-temperature region of the outlet in flame of mouth, therefore have very strict requirements to the performance of burner material, it is not so easy for causing to burn
Mouth falls off, to influence the performance and used life of stove equipment.And combustion gas and air all lead in the same heat-accumulating burner
Burning in stove, due to the needs of air inlet, exhaust and accumulation of heat, under the switching of reversal valve, two heat-accumulating burners want rotation as air blast
Or the channel of air inducing, original work are the heat-accumulating burner of air blast side, to stop combustion gas and the output of air rapidly in commutation, change
The flow direction of gas becomes air inducing and accumulation of heat channel, if if at this moment the combustion gas in burner does not empty or reversal valve slightly leaks, so that it may
Tempering or explosion can be generated, more very has the generation of de- fiery phenomenon, security performance is to be unable to get guarantee at all.It is burning simultaneously
The design of heat storage should consider the arrangement of combustion gas spout and air port in mouth, consider air inducing accumulation of heat and anti-backfire effect again
Fruit makes complicated, the manufacture difficulty increase of burner and heat storage.And the requirement to commutation valve performance and quality is also higher.
In use, it is generally recognized that reversal valve is a stealthy hacker, and there is the potential danger that generation is blown out at the moment.In whole system
Interdependency between each component is very big, and unstability factor increases, and often a widget performance is bad or damages,
It can cause larger failure or accident.So the stability and reliability of above-mentioned technical proposal work are relatively low, also it is unfavorable for very much
Maintenance and Repair usually.
Later someone is short for the above flame, is easily tempered, and job stability and safety are poor, complicated, safeguards inspection
It repaiies inconvenient defect to be improved, a kind of disperse formula Regenerative Combustion System occurs, accumulation of heat babinet is set on burner both sides,
Combustion gas and wind are separated, combustion type is changed, combustion gas enters from respective burner in stove respectively with air to be mixed
It closes, forms the burning of disperse formula in stove, flame is long, and the requirement to burner material is relatively low, is improved relatively using the longevity to stove.
Because air is separated with combustion gas, the requirement to the quality and performance of commutating device is improved, will not be because of commutating device
Not in place, mass defect is acted, the equal minor issues that do not work influence production, safeguard and simplify.But use process actual
In, outlet air with to go out combustion gas crosswind pressure big with air pressure, cold-zone can be gone into stove, non-uniform temperature occurs, stove, which expands, to differ, and makes
It is beaten and is torn open with the service life, fusing cold-zone can not normal synchronized fusing.Because of air channel and the fixed angle in combustion gas road, until making after filling it up with material
Effect is not achieved with disperse with mixing velocity when heat preservation, or even has little time mixing and is drawn into air, cannot fully burn,
Also waste material.

On kiln, burner is pushed to be swung between two heat storage tanks；The burning torch and flame monitoring are fixed on the burner, and burning torch is certainly
With small fire detection device, acquiescence burning torch is ever-burning flame.
The angle that the heat storage tank is obliquely installed is 15 ~ 35 degree, and angle is determined by the design of stove size.
The angle of the execution cylinder burner swing is 15-80 degree.
The execution cylinder push the swaying direction of burner be root heat storage tank at air blast when switch, burner outlet with
Heat storage tank outlet is at 10 ~ 85 degree of intersections in stove.
Heat storage tank of the present invention is obliquely installed in pairs, and angle determines that burner is arranged in two accumulation of heats by the design of stove size
Among babinet, combustion gas is mixed with the burner mouth that the air of circulation leads in heat storage tank in stove and makes into mix in stove, it can be safe
Ground carries out switch operating between air blast and air inducing operation, completely eliminates the tempering phenomenon that burner mouth mixes at heat storage tank, also from
Various aspects have prevented the generation blown out.
The fully mated switching with heat storage tank of action of the execution cylinder of the present invention, when accumulation of heat babinet is at Overblow state,
Execution cylinder pushes and pulls burner, by burner outlet and heat storage tank air blast row at intersection, realizes what heat storage tank gushed out
The combustion gas that high temperature air is sprayed with burner carries out controllable mixing, and intersection length shortens, and blending space lengthens, disperse campaign
It carries out in advance, under the auxiliary of air pressure, flame is long and dissipates, and obtains reliable disperse formula burning so that entire furnace body is heated
Uniformly, the cold-zone for reducing heating, reduces differences in expansion, and the requirement to burner material is relatively low, itself makes to stove equipment
It is improved with performance is opposite with service life.
The burning torch and flame monitoring of the present invention is fixed on the burner, and burning torch carries small fire detection device, gives tacit consent to point
Firelock is ever-burning flame, mainly realizes igniting automation, even more ensure that when stove is in cold operation, prevent heat storage tank from switching
The rough burning that burner flame is generated by impact in the process, and with small fire detection device, to ensure running normal shape
State.
Two heat storage tanks of the present invention share a burner, and compared to original, there are two heat storage tank, respectively one burner of setting comes
It says, since heat storage tank need to only improve the performance for the switching equipment that commutates with quality requirements, and not by air and flue gas
It can be because switch failure leads to the work that cannot continue, that is to say, that even if switching stopped, the progress of burning will not be influenced,
Reduce influence of the switching to production；Again because accumulation of heat babinet no longer guards the work of ignition, being even more from structure type can
It is compact with succinct, flexibly.
The present invention is transported to combustion apparatus by the combustion air after preheating and participates in burning, than combustion air without pre-
The combustion thermal efficiency of heat improves 58%, energy saving consumption 45-55%；Than traditional heat accumulating type and disperse formula heat-accumulation combustor thermal effect
3% should be improved, energy saving consumption 5% is truly realized using effect that is efficient, energy saving, economic, maintaining easily.
