Abstract
The invention provides a low-carbon gas fuel which is prepared from hydrogen and natural gas according to a certain proportion. Theoretically, the hydrogen and the natural gas can be mixed according to any proportion. In practical application, the volume fraction of the hydrogen is preferable to be 1-50 percent. For comprehensively utilizing respective fuel characteristics of the hydrogen and the natural gas, the fuel has the advantages of high combustion efficiency and low emission.
Description
The present invention relates to the geseous fuel technical field, refer in particular to a kind of low-carbon (LC) geseous fuel and manufacture method thereof.
Geseous fuel commonly used at present is divided into four classes substantially:
The first kind is a Sweet natural gas, also claims coal-seam gas.China widelys popularize, but china natural resources is few and skewness.The pipelines such as transfering natural gas from the west to the east that built up are at present transported to the each province, east with Sweet natural gas.
Second class is an acetylene, and promptly acetylene gas be to add the water reaction by carbide of calcium to generate, and the manufacturing of carbide of calcium (also claiming calcium carbide) must expend a large amount of electric energy, and production cost is higher, pollutes big.
The 3rd class is a coal gas, is to add water by coal when the high temperature to make, owing to will consume a large amount of coal and emit pollutent such as carbonic acid gas, cost is higher and seriously polluted.
The 4th class is a hydrogen.Hydrogen is the novel energy carrier.Hydrogen can make with gasifications such as coal, Sweet natural gas, oil, reformation, and also available brine electrolysis makes.Hydrogen has been used for the rocket launching of space flight and aviation, and hydrogen energy automobile is used it in research now.Because the special property of hydrogen does not see that as yet it is used for the report of industrial fuel.
The purpose of low-carbon (LC) geseous fuel of the present invention is to provide a kind of new low-carbon (LC) geseous fuel and manufacture method thereof.
Hydrogen and Sweet natural gas can mix with arbitrary proportion in theory.In fact, in order to use conveniently, the volume fraction of hydrogen is 1%-50% in the propellant combination of the present invention, and all the other are Sweet natural gas.Because the minimum ignition energy of hydrogen only is 0.02 little Jiao, is 1/14th of Sweet natural gas.Its spread coefficient is 0.63cm
2/ s is three times of Sweet natural gas, and the flame propagation velocity of hydrogen is 3.1m/s, approximately is ten times (seeing Mao Zongqiang work " green energy resource of Hydrogen Energy-21 century ", China's chemical industry press, version in 2005, the 280th page) of Sweet natural gas.Therefore, hydrogen-natural gas mixed has new fuel characteristic, is fit to uses such as Industrial Boiler, kiln, domestic gas appliance.
The major advantage of low-carbon (LC) geseous fuel of the present invention is to utilize the industrial foundation of present stage to advance the application of hydrogen aspect the energy (previous, hydrogen is mainly used in industrial chemicals), make the whole nation and even the whole world turn to low-carbon (LC), the carbon-free energy, realistic plan is provided by existing fossil energy.
The enforcement of low-carbon (LC) geseous fuel of the present invention:
Fig. 1 is a process flow diagram of the present invention.Consult Fig. 1.The enforcement of low-carbon (LC) geseous fuel of the present invention is to be finished by following steps:
1. the Sweet natural gas of this gas mixture storage is irritated gas source in 1 in chemical by-product, or coal-seam gas, Sweet natural gas, coke-oven gas etc., but concentration of natural gas should meet national Sweet natural gas combustion gas standard.
2. the heat exchange gas compress cell 2, are used for regulating according to the processing requirement of mixing tank the temperature and pressure of Sweet natural gas.
3. hydrogen gas fire arrester 3, prevent the hydrogen tempering, play the safety control effect.
4. the hydrogen of the hydrogen in the hydrogen of this gas mixture storage filling 4 derives from various approach: chemical industry by-product hydrogen (coke-oven gas, blast furnace gas, chlor-alkali manufacture gas etc.), fossil oil hydrogen manufacturing, mineral hydrogen manufacturing, water electrolysis hydrogen production, biomass hydrogen preparation, density of hydrogen should be greater than 99%.
5. hydrogen heat exchange compress cell 5 is used for the temperature and pressure according to the processing requirement adjusting hydrogen of mixing tank.
6. the gas mixture basin 6, require accurate measurement, guarantee that mixture strength meets the needs of downstream user.When the volume fraction of the hydrogen in the gas mixture is equal to or less than 1%, allow its hydrogen to be derived from the knallgas of particular electrical Xie Shui equipment, allow the oxygen volume fraction less than 1/2 hydrogen volume mark this moment.
7. when keeping in repair hydrogen or natural gas system, can utilize by-pass valve 9 or 10.

Claims (2)
1. low-carbon (LC) geseous fuel, it is characterized by: this fuel mainly is made up of hydrogen and Sweet natural gas.Wherein the volume fraction of hydrogen is by 1%-50%, and all the other components are Sweet natural gas.
2. the preparation method of a low-carbon (LC) geseous fuel is characterized in that:
(1) hydrogen in the hydrogen basin derives from various approach: chemical industry by-product hydrogen (coke-oven gas, blast furnace gas, chlor-alkali manufacture gas etc.), and fossil oil hydrogen manufacturing, mineral hydrogen manufacturing, water electrolysis hydrogen production, biomass hydrogen preparation, density of hydrogen should be greater than 99%.
(2) gas source in the Sweet natural gas basin is in chemical by-product, or coal-seam gas, Sweet natural gas, coke-oven gas etc., but concentration of natural gas should meet national Sweet natural gas combustion gas standard.
(3) even for guaranteeing gas mixture, be before entering gas mixer, each temperature self-regulating of hydrogen and Sweet natural gas and pressure.
(4) in mixing tank, require accurate measurement, guarantee that mixture strength and precision meet the needs of downstream user.
(5) when the volume fraction of the hydrogen in the gas mixture is equal to or less than 1%, allow its hydrogen to be derived from the knallgas (being commonly called as Blang's gas) of particular electrical Xie Shui equipment, allow the oxygen volume fraction less than 1/2 hydrogen volume mark this moment.
