Know-why of the present invention:
1. guarantee that energy discharges maximum value, to improve efficiency of combustion
The material that burning relates generally to is fuel and oxygen.Generalized case, fuel are gaseous state (as Sweet natural gas), liquid (as various fuel oils) and solid-state (as coal), and oxygen is then directly taken airborne oxygen.The content of nitrogen is about 4 times of oxygen in the air, though these nitrogen are not participated in burning, is heated in combustion processes, and therefore in order to make in the air 20.9% oxygen participate in burning, the energy of loss is huge.As everyone knows, fuel all is hydrocarbon polymer, and after fuel entered the pyritous burner hearth, hydrocarbon key ruptured, and generates CO with oxygen reaction
2And H
2O, and sub-fraction is because incomplete combustion generates CO and H
2O runs away from flue.Burn in order to allow an amount of fuel and an amount of air form optimum proportion, ignition dope among the present invention is that fuel in time replenishes required oxygen in cracking process, in the input that guarantees farthest to reduce under the prerequisite of full combustion of fuel air, the loss of this form is minimized.
2. " microexplosion " phenomenon and water-gas reaction
The burning of coal of having added additive is the process of a complexity, we replenish the moisture of 5～60Kg according to the requirement of the different type of furnaces, under specific temperature and pressure, the water that replenishes fully disperses under additive effect of the present invention, refinement, form ten hundreds of water molecules groups, and the carbon particles thorough mixing that produces when the Pintsch process with coal, " microexplosion " phenomenon takes place in the vaporization of expanding rapidly under the high temperature action in the combustion chamber, it is atomizating phenomenon, moment forms a relative anoxybiotic microenvironment, under the catalytic pyrolysis of additive agent, generation has not the atom or the atomic group of valence electron, for example H in pairs
2, CO ,-OH ,-CH
3Deng, carbon particles can fully be burnt, improved rate of combustion, reduced the smoke content in the smoke evacuation, increased the heat that produces.
3. high-frequency vibration, catalytic pyrolysis and reorganization notion
Under the effect of additive of the present invention and the high-heating radiation of burner hearth high temperature, the high frequency microexplosion takes place in the non-ferrous metal salt in fire coal and the additive under katalysis, generate free electron, form charge cloud, polarizing effect under the similar highfield appears in charge cloud under strong thermal radiation effect, high frequency knock against each other bombardment carbochain causes the chain reaction in the combustion processes.Produce some highly active particulates in the chain reaction process, as the hydrogen particle ,-OH ,-CH
3Deng the participation burning.In a single day this reaction process causes, and just can induce down at additive automatically go on.Carbon-chain structure in the fire coal is being implemented to attack in the reforming process the former H that should discharge of a part simultaneously
2O is reassembled as the flammable energy and combustion-supporting gas by fission again, participates in oxidation once more, has improved efficiency of combustion.
In sum, various organic and inorganic compounds decompose under different starting temperatures, activate the energy of nascent state free radical under the high frequency microexplosion, impel the bulk and coal seam layering in coal seam thoroughly to burn, and violent burning.Under the effect of additive, coal-fired High energy water coal gas, the hydrogen particle clusters etc. of forming in stove have impelled the flame temperature rising, and have driven the rising of flame flame envelope temperature, increased flame length, flame density, flame area is accelerated the rate of combustion in the boiler, radiation and convective heat transfer increase, improve the energy density of unit volume fuel, thereby improved the thermal value of unit of fuel, reached the effect of economizing on coal.
