Referring to the above-mentioned, the technical personnel of this specialty can know, and traditional adoption air is as the oxidant source and adopt the oxygen boosting as the combustion organization difference of oxidant source, the utility model discloses a method has not only adopted the oxygen boosting as the oxidant source, has adopted the catalytic catalyst in addition in order to increase the combustion organization method of arousing the quantity of singlet oxygen, and process the utility model discloses a technology and device, the oxygen boosting can form higher singlet oxygen cardinal number after the catalysis, and the singlet oxygen can directly participate in the oxidation reaction with fuel because of having higher activity, has reduced the reaction activation energy from a certain sense, perhaps has consumed the reaction less exothermic, has indirectly promoted fuel heat energy output, therefore energy-conservation.
In fact, the combustion process of coal, natural gas, oil, petroleum coke and other fuels is essentially an oxidation reaction system. Most boilers and kilns adopt air as an oxygen source for the oxidation reactions, and when the oxidation reactions are carried out, oxygen molecules cannot directly carry out chemical reactions with fuels, but need to absorb enough energy to break chemical bonds of the oxygen molecules into singlet oxygen (oxygen atoms) before the oxygen molecules directly participate in combustion chemical reactions: taking carbon as an example, 1mol of carbon reacts with oxygen to generate 1mol of carbon dioxide, which releases over 390 kilojoules of heat energy, but the energy required for breaking the chemical bonds of oxygen, i.e. the energy required for forming "singlet oxygen (first excited state, second excited state)" is about 250 kilojoules, which is derived from the heat energy generated by burning the exothermic reaction (for an endothermic reaction system, the energy can only be derived from external temperature and external pressure), i.e. the excitation process needs to "internally consume" nearly 63% of the heat energy, and obviously, the energy is energy-saving by consuming less energy.
The oxygen-enriched catalytic combustion technology is a technological progress of 'nature of law, human body' and a person, and is a very magical animal, and the human body is a 'high-efficiency low-temperature furnace', and because the blood in the body contains porphyrin catalysts which can directly break chemical bonds of 'oxygen molecules' to excite singlet oxygen, the porphyrin catalysts can excite the oxygen breathed by the person into singlet oxygen at normal temperature (37 ℃), and can be converted into hydrocarbon such as amino acid and the like with food eaten by the person, so that the oxygen-enriched catalytic combustion technology can directly complete combustion chemical reaction at normal temperature (37 ℃), convert the energy (heat energy and the like, maintain the body temperature of the human body and generate carbon dioxide and water to be breathed out of the body.
The utility model discloses an oxygen boosting catalytic combustion technique is based on can arousing the catalyst that oxygen molecule is "singlet oxygen (oxygen atom)" to realize energy-conserving purpose, and its core technological principle is the required chemical bond energy of oxygen molecule fracture chemical bond formation "singlet oxygen (oxygen atom)" that participates in the chemical reaction of burning through the catalyst reduction promptly, directly arouses the oxygen molecule for singlet oxygen to reduced the reaction activation energy, consumed the reaction less and released heat, indirectly promoted fuel heat energy output.
Therefore, the utility model discloses an oxygen boosting catalytic combustion process scheme, different from traditional oxygen boosting combustion, its process objective is absolutely not simple with the cleaner of fuel burning, more thoroughly (actual test shows, 93% of thermal efficiency burn the boiler of natural gas, carbon monoxide discharges and is almost 0, incomplete combustion loss has been very low, adopt oxygen boosting catalytic combustion still can practice thrift 15% natural gas), also not because the heat loss that has reduced the flue gas volume and taken away is so simple, those all are the "by-product" of burning the tissue aspect, not essence, oxygen boosting catalytic combustion technology's essence is to "oxygen" energy, rather than to fuels such as "carbon, methane, oil" energy. More importantly, the oxygen-enriched catalytic combustion-supporting process method combining oxygen enrichment and catalysis is adopted, so that the flow and purity requirements of an oxygen source are greatly reduced, the investment of oxygen equipment and the operation, maintenance and maintenance costs of the oxygen equipment are greatly reduced, and especially the energy consumption of the oxygen generation equipment is reduced.
Therefore, in fact, oxygen enrichment, ozone and catalyst can be applied to energy conservation of combustion chemical reaction, wherein the oxygen enrichment can improve the probability of exciting singlet oxygen, the ozone carries singlet oxygen, the catalyst is more serious, and the singlet oxygen can be directly excited even at low temperature, so that the activation energy is reduced, the reaction heat release is less consumed, and the fuel heat energy output is indirectly improved, for example
Tests show that the catalyst can reach activity at present, the catalyst can be taken back by about 20 percent, and can be applied to various combustion chemical reaction systems to improve the heat energy output of fuel, or reduce the activation energy required by the 'oxygen molecule' for breaking chemical bonds into 'singlet oxygen (oxygen atoms)' and indirectly improve the heat energy output.
To sum up, the utility model, when using oxygen-enriched air, even pure oxygen, especially combining with catalyst as oxidant, oxidant excitation technique source to implement combustion organization, because oxygen-enriched, pure oxygen especially catalytic environment greatly changes the combustion characteristic of fuel, except that fuel is easier to burn out, can reduce excess air coefficient and reduce exhaust heat loss, more importantly can reduce the activation energy needed by combustion chemical reaction, and improve the conversion and transmission efficiency of fuel heat energy, therefore, the method of the utility model is different from the combustion organization which is mostly based on air as oxidant source in the tradition, oxygen-enriched catalytic combustion is a brand new combustion organization which is based on oxygen-enriched or high-energy oxygen-enriched after catalytic activation as oxidant source, can realize the process purposes of energy saving or yield increase and the like under the condition of not changing client process temperature and operation habit (temperature is high, namely reducing fuel or combustion-supporting wind), it is also because the nature of the oxygen-rich catalytic combustion technology requires energy for "oxygen" rather than for "carbon, methane, oil" and other fuels. Therefore, there are significant technical advantages:

the oxygen enrichment and the catalyst can be directly added along with fuel flow (coal, natural gas, oil and the like) by pipelines without replacing a burner of a user or modifying a kiln or a boiler;
(5) the energy-saving effect can be adjusted by changing the dosage of the catalyst
The energy-saving effect can be simply adjusted by changing the consumption of the oxygen enrichment and the catalyst;
(6) simple and reliable process equipment
Preferably such as
The modularized and standardized membrane separation equipment developed by science and technology has extremely high reliability, particularly, oxygen is prepared by directly utilizing user compression equipment, and maintenance-free can be realized because the rest parts do not have power equipment;
