Owing to using technical scheme as above, there is advantages that
Verticle gas hot Media Oven energy saver of the present invention: 1, film oxygen enriching equipment prepares oxygen-enriched air, and raising helps
Combustion air oxygen content；The oxygen content air more than 20.93% is called oxygen-enriched air.Oxygen-enriched air participates in burning and has significantly joint
Energy and environmental protection effect.At the same temperature, oxygen-rich concentration is the highest, burns the most complete, and blackness of the exhaust is the lowest, energy-conservation and environment protecting
The best；Membrance separation oxygen generating plant is to utilize to have the high molecular polymerization fibrous material of special selection separation property as resolution element,
Under certain driving force effect, oxygen or the many components of oxygen is made to be enriched with through film；Oxygen-enriched air can improve flame temperature.Make
Nitrogen amount can be made to reduce with oxygen-enriched combustion technology, air capacity and exhaust gas volumn all substantially reduce, therefore flame temperature is along with combustion air
The increase of middle oxygen proportion and significantly improve.The oxygen concentration of combustion air often promotes one percentage point flame temperature and improves 35 DEG C.
Oxygen-enriched air can be accelerated burning velocity and promote burning completely.With oxygen-enriched combustion technology, burning velocity can not only be improved, it is thus achieved that
Preferably conduction of heat, after temperature improves simultaneously, beneficially combustion reaction, promote that burning completely, is inherently eliminated smoke contamination；
Oxygen-enriched air can reduce the ignition temperature of fuel.The ignition temperature of fuel is not constant, and burning-point as aerial in CO is 609
DEG C, and burning-point in pure oxygen is only 388 DEG C, so using oxygen-enriched, pure oxygen burning can improve flame intensity and increase release heat
Amount etc.；Oxygen-enriched air can reduce the flue gas discharge capacity after burning.With air-breathing, the N2 accounting for volume 4/5 does not participate in combustion-supporting, and with
Burning and take away a large amount of heat energy, as combustion-supporting with oxygen rich gas, the capacity after burning reduces, thus improves efficiency of combustion；Rich
Oxygen air can increase heat utilization ratio.The utilization rate of heat is increased by oxygen-enriched, Pure Oxygen Combustion Technology, as by normal air
Combustion-supporting, when heating-up temperature is 1300 DEG C, its available heat is 42%, and with 26% dense oxygen air-breathing time, available
Amount is 56%, and it is the fastest, therefore at this oxygen that oxygen concentration its heat utilization ratio between 21%～30% improves with oxygen concentration and raises
To improving heat utilization ratio most preferably in concentration range, therefore energy-saving effect is the best；Oxygen-enriched air can reduce air excess system
Number.Oxygen-enriched, pure oxygen burning increases in atmosphere along with oxygen content, and nitrogen amount declines, and can suitably reduce the coefficient of excess of air, this
Sample, fuel consumption is the most corresponding to be reduced, thus saves the energy；Owing to burning-point oxygen-enriched, that Pure Oxygen Combustion Technology can make carbon reduces, burning
Complete and strong, flame degree of filling is good, improves the bulk temperature of burner hearth, and object is exhausted to the heat of ambient radiation and this object
The biquadratic of temperature is directly proportional, here it is " fourth-power law " radiation law.
2, double to combustion air and fuel temperature preheatings can be advantageously reduced by air prewarming device and fuel preheating equipment
Coefficient of excess air, improves ignition temperature, reaches energy-conservation fuel-saving effect；It is the combustion gas of 3000kJ/m3 for calorific capacity,
Its temperature often raises 1 ° of C, and will absorb heat 1.4512kJ/m3, and the air capacity required for the lm3 combustion gas of this calorific value that burns only is absorbed heat
0.8306kJ/m3.In this case, fuel gas temperature is increased to 100 ° of C, and theoretical temperature combustion can be made to raise 52 ° of C, and combustion-supporting
Air themperature raises 100 ° of C, and theoretical temperature combustion raises 29 ° of C.When combustion air and the double preheating of combustion gas, improve Theoretical combustion temperature
The effect of degree is both effect sums respectively.When the combustion gas that calorific capacity is 3000kJ/m3, can by coefficient of excess air from
1.10 reduce to 1.05, and theoretical flame ignition temperature is by about 20 ° of C of raising.
3, flue gas heat recovery equipment can recycle flue gas heat and substantial amounts of steam latent heat, reduces outer row
The sulfur content of flue gas.
