Description
Affiliated technical field:
The utility model relates to a kind of moisture industrial alcohol (or other low-carbon (LC) liquid fuel), be aided with the complementary collocation of diesel oil, become the low-carbon (LC) fuel combination, double fuel is alternately sent into the pin hole pipe, pressure injection to the helix tube of high temperature red heat state, instantaneous gasification, blowing air mixture, the swift and violent burning in igniting back, energy-efficient middle-size and small-size burner.
Background technology:
Countries in the world (refer generally to kerosene to liquid fuel at present, diesel oil is the high carbon chain hydrocarbon) all adopt the spray burning mode to burn, promptly use compressed air, use blower fan, with high-pressure water vapor the fuel oil pencil is directly injected in the combustion chamber, forming as far as possible little mist of oil at last drips, ignition immediately, the oil droplet particle is thin more, combustion position is just good more, in fact different burners, oil mist particles differs in size, combustion position is widely different, people need only from MISSILE LAUNCHING, motor vehicle exhaust emission, and the combustion position of various fuel oil facilities is observed, the capital finds that the burning of oil always produces black smoke, carbon powder dust, even coking, such as: 300,000 tons of ethylene project data are pointed out: the diesel oil equipment for gasification of ethylene producing device, just must regularly clear up the coking residue.Yet the combustion position of all gas fuel is all very good, because it very easily disperses, easily mixes with air, makes burning very abundant.If with the fuel Heating gasification, the liquid volume of its volume ratio increases more than 200 times, also can be easy to disperse, if it the burning bad phenomenon occurs, has just solved as long as increase the air quantity problem.
Since it is so, why is various countries burning expert to jet combustion negated? this is because kerosene and diesel oil all are the high carbon chain molecules, in closing pipe line during the high temperature heating and gasifying, its stability raises with temperature and descends, thermal cracking can take place in molecular structure, big molecular breakdown becomes little molecule, the reaction temperature difference, the degree that reaction is carried out is also different with product, if under high-temperature very, the oil molecule is decomposed into carbon and hydrogen with fast speed very, and a large amount of carbon particles are separated out and can be made pipeline produce carbon deposit, even coking becomes lump, thereby stops up oil pipe and nozzle.Pure diesel oil flame temperature helps N in the air up to more than 1,000 degree simultaneously
2Oxidation generates the NOx pernicious gas, and this two hang-up all is difficult to solve.
For industrial alcohol (being alcohol fuel), it is low-carbon (LC) molecule C
2H
4OH, calorific value is low volatile during burning, and its burning velocity and flame propagation velocity are exceedingly fast, inflammable and explosive abnormally dangerous, various heating furnaces are not used it, only when the fuel oil short supply, miscible with certain proportion and gasoline, make engine replacing fuel, it is mainly used in industrial chemicals.The raw material of manufacture alcohol is not a grain, but refine sugar waste material bagasse, megasse, maize straw, Ipomoea batatas, non-edible potato ... or the like.China's alcohol output surplus is classified as one of compression project by National Development and Reform Committee at present.
