Description
The present invention is relevant with Thermal Power Engineering, and is or rather, relevant with the combustion method and the equipment thereof of viscous liquid fuels.
The present invention is best suited for the heavy viscosity defective material of combustion and pyrolysis oil and oil shale generation.
In addition, also can be used to metabolic water coal slurry, heavy oil coal slurry, coal slime slurry according to liquid fuel combustion method of the present invention and combustion apparatus and contain the suspension of the industrial wastewater of following composition: organic solid, organic liquid, organic generation poisonous substance, the public life career waste liquid in city, agricultural production waste liquid etc.
The method of known burning viscous liquid fuels (for example No. 1233082 patents in Germany of announcing in 1967, international invention classification F2SD) is that the gas that fuel and pressure are higher than fuel pressure is mixed, thus atomized fuel.
Mix with oxidant, atomized fuel becomes flammable mixture then, again flammable mixture is heated to burning-point.
The gas and the oxidant that all act as a fuel and atomize in the known method with air.
Known method can be used for combusting heavy oil type heavy crude fuel effectively.
Yet at present, particularly lack heavy oil and other petroleum fuels, produce the necessity that defective material is made fuel, as the heavy defective material of pyrolysis oil, oil shale, coal and other organic energy etc. just utilization and extention occurred owing to lack fuel source.Such heavy defective material uses the method for known burning viscous liquid fuels not burn effectively, because their viscosity height, above the viscosity of heavy oil, their combustion heat is low, organic component content instability in the fuel stream, and contain the solid composition in the liquid fuel.The solid composition hampers viscous liquid fuels and effectively atomizes.
Empirical evidence, when burning with known method, aforesaid heavy viscous liquid fuels can not stably be lighted and burning effectively, because their viscosity height, the temperature of flame is very low, organic solid composition in the fuel can not completing combustion, and wherein some is not burnt, but is pulled away with combustion product.
This situation can be done such explanation: liquid fuel has been burnt, solid fuel particle incomplete combustion.Because when burning viscous liquid fuels oil droplet, in fact consumed the most of oxygen in the oxidant, the flammable performance of liquid fuel is more active than the solid composition in the fuel.
With known combustion method combustion of high viscosity liquid fuel, owing to there is not swirling oxidant stream.Ignition effectiveness is not high enough.
Flame just can not fully scatter like this.So need effectively igniting, the various heavy fuels (comprising the two-phase fuel mixture) that especially need to burn reliably, and under fuel stream different parameters situation, flame is fully scattered.
The used equipment of method of realizing known burning viscous liquid fuels is (for example No. 1233082, the DRP of announcing in 1967, international invention classification F23D) known.It has a housing, coaxial installation one fuel feed pipe in the housing.
Air supply pipe is arranged on the combustion apparatus and be the assembly of fuel atomization air feed, also have the oxidant supply pipe, so that oxidant and fuel form flammable mixture.
Gas supply assembly is that a jet pipe and fuel feed pipe fit together, and is thicker than fuel feed pipe, is contained in the back of the supply pipe port of export and coaxial with it.Many passages are arranged on the jet pipe sidewall.Gas comes from air supply pipe, enters the jet pipe chamber.The cross-sectional diameter in jet pipe chamber is bigger than fuel feed pipe.Jet pipe is a mixing chamber.Its effect is that the fuel stream from the expansion of fuel feed pipe is mixed with gas, so that atomized fuel.
Through the fuel feed pipe outer surface with it at a distance of the circular passage of the jet pipe annular wall inner surface of certain distance, through aforesaid each passage, air supply pipe communicates with gas supply assembly jet pipe chamber.Passage is distributed on that part jet pipe wall that is connected with fuel feed pipe.
One circular passage is arranged between jet pipe outer surface and the shell inner surface, and it also communicates with air supply pipe, and carries out the transition to axial passage-contraction road along the mixture flow path direction of atomized fuel and gas.The contraction road is actually the continuity part in fuel feed pipe road, and there is first divergent contour nozzle in the exit, then shrinks along fuel flow directions to communicate with the combustion chamber.
The vertical geometrical axis radial arrangement of the relative fuel feed pipe of oxidant supply pipe.
Second shrinks the road makes the oxidant supply pipe communicate with the second divergent contour nozzle.The second divergent contour nozzle is positioned at the exit of housing, and facing to the combustion chamber, the first divergent contour nozzle communicates with it from fuel feed pipe one side.
Burning heavy high viscosity fuel liquid is suspended with the two-phase fuel of a large amount of solids in the combustion of liquid, and the combustion heat is lower than the fuel of heavy oil combustion heat, or the combustion heat is significantly to reducing the fuel that direction changes, and the effect of known device is relatively poor.
Because air vent is distributed on the jet pipe of fuel feed pipe outlet, mixing enlarges partly at jet pipe and carries out, and the fuel flow point is cleaved into thin dripping, so fuel just can not mix fully subtly with oxidant.
Change in fuel composition, viscosity and the quantity supplied with, and under different fuel stream supply conditions, the above-mentioned distribution situation of jet pipe wall upper vent hole can not guarantee that promptly fuel atomizes subtly.
The radial arrangement of oxidant supply pipe from the coaxial arrangement that this pipe leads to the annular space of the second divergent contour nozzle, can not guarantee that fuel lights a fire reliably.
Main task of the present invention provides the method and the equipment thereof of burning viscous liquid fuels, and this method and apparatus will guarantee that high viscosity fuel liquid and oxidant mix fully subtly and igniting reliably, and burning with being effective.
The solution of this task is as follows: the method for burning viscous liquid fuels is that fuel is mixed with the gas higher than fuel pressure, and with atomized fuel, fuel mixes with oxidant stream then, becomes flammable mixture, again flammable mixture is heated to burning-point.The used gas of the present invention is steam and air mixture.Gaseous mixture is mixed by superheated vapour and air, directly sends in the fuel stream, forms bubble in fuel stream.Oxidant stream then is pre-formed eddy flow.And flow the periphery along alveolate fuel and send into.
Can bring into play superheated steam with steam and air mixture as gas can be with the characteristic that is evaporated than light fraction in the heavy heavy fuel.Lighter fraction and the air in the steam and air mixture form uniform homogeneous blend.In addition, superheated steam has improved the temperature and the flowability of heavy fuel, has reduced the surface tension of heavy fuel.
When steam and air mixture is directly sent into fuel stream, when fuel before the fuel supply pipe comes out and spreads, form bubble, contain the uniform homogeneous blend of air and heavy fuel evaporation fractional composition in the bubble, concentrating the heavy fraction of fuel in the bubble shell, as tar.When burning heavy viscosity fuel and solid fuel formation biphase mixture, also assembling the solid fuel particle in the bubble shell.The inflammable uniform homogeneous blend of being made up of the fuel fraction and the oxidant of vaporization in the bubble has improved the igniting and the burning of heavy fraction and solid matter greatly.
Oxidant is pre-formed eddy flow can guarantee that bubble mixes mutually with high-temperature combustion product.Oxidant stream sucks these high-temperature combustion products from the flame combustion district, and is full of the flame expansion area.This has just guaranteed the reliable ignition of uniform homogeneous blend in the bubble, and the burning of the solids of bubble shell and existence.Send into the oxidant eddy flow along fuel stream periphery, guaranteed that the fuel stream that contains bubble mixes and the maximum area that contacts with oxidant stream.
The weight flow of steam and air mixture preferably remains on 0.9～5 times of weight of fuel consumption.
The part by weight that keeps above-mentioned steam and air mixture and viscous liquid fuels can make fuel light a fire reliably and burning fully.
If this ratio is lower than 0.9, just the air capacity deficiency in the steam and air mixture so as fuel light a fire reliably.
If this ratio is higher than 5, because fuel is diluted by too much air, the flame temperature of fuel combustion is lower than optimum temperature.
When the oxidant eddy flow was sent into, it and the angle of spread that geometrical axis became that fuel flows preferably remained in 10 °～20 ° scopes.
The angle of spread is meant the angle between oxidant and viscous liquid fuels eddy flow maximal rate vector and the non-eddy flow axis of fuel.
Empirical evidence, the value of the oxidant stream angle of spread and flame development angle equates.
The oxidant eddy flow angle of spread in above-mentioned scope can make heavy fuel reliable ignition and completing combustion.
If the fuel flame angle of spread is less than 10 °, high-temperature combustion product can reduce or complete obiteration, and high-temperature combustion product is given me a little the combustion gas bubble by oxidant stream from the suction of flame combustion district, so igniting and efficiency of combustion will reduce.
Flame development angle is greater than 20 °, can make to suck flame and launch in the district combustion product arranged not only, also has oxidant.Oxidant can make the temperature of combustion product sharply descend, and just reduces the ignition ability of combustion product.
Task of the present invention also solves by combustion apparatus.Have in this equipment housing and oxidant supply pipe, one with the coaxial mounted fuel feed pipe of housing, also have one gas sent into the assembly that makes its atomizing in the fuel.According to the present invention, gas supply assembly is made fan-shaped tubular, surrounds the part of fuel feed pipe from below.The aperture that the assembly inner chamber distributes on its wall communicates with fuel feed pipe.The oxidant supply pipe can make the oxidant stream rotation.Oxidant is sent in fuel feed pipe outlet back.
Gas supply assembly is made fan-shaped tubular, and surround the some of fuel feed pipe from below, and can be reliably, the gas flow that not will all need by fuel quantity changes in the fuel feed pipe influence is sent into fuel and is flowed, and can strengthen the effect of gas and fuel room, promote their mixing.Even when fuel flow rate reduces, the effect of this effect can not reduce yet.
The aperture that distributes on the fuel feed pipe tube wall is communicated with gas supply assembly and fuel feed pipe.These holes can make gas contact more fully with viscous liquid fuels, and gas is sent in the mode of a lot of strands of jets, increase the gross area that gas contacts with viscous liquid fuels, promote the generation of bubble.
Contain solids in viscous liquid fuels, when promptly the calorific value of fuel reduced, the generation speed of bubble can not reduce yet.
The above-mentioned position of oxidant supply pipe makes it can produce the oxidant eddy flow with maximum centrifugal acceleration around the viscous liquid fuels stream that contains bubble.In this case, centrifugal acceleration be evenly distributed on viscous liquid fuels stream around.
The reasonable mount scheme of oxidant supply pipe is to make its geometric longitudinal axis depart from the housing geometric longitudinal axis, and becomes an inclination angle with it, and oxidant is rotated.
Mutual alignment and inclination angle behind the above-mentioned oxidant supply pipe longitudinal axis and the housing axis runout are wanted and can be made the oxidant stream rotation with the simplest method.
Export distance between the nearest hole apart from this on fuel feed pipe outlet and the tube wall, preferably equal 3 to 6 times of fuel feed pipe channel diameter.
Export as above distance between the nearest hole apart from this on fuel feed pipe outlet and the tube wall, make the speed of fuel feed pipe exit viscous liquid fuels stream even, bubble can evenly be distributed in viscous liquid fuels stream, make viscous liquid fuels obtain the same ignition intensity on every side.
The shape of gas supply assembly cross section is preferably fan-shaped, and central angle is 90 °～120 °.
This cross sectional shape of gas supply assembly, the gas flow that can will all need is sent into the fuel feed pipe bottom that is full of viscous liquid fuels.In addition, when sending the viscous liquid fuels that contains solids, the gas supply assembly of this shape can prevent that solids are deposited in the fuel feed pipe tube wall, thereby has improved mixing condition, has strengthened the igniting of viscous liquid fuels stream.
For the fuel full level in different viscous liquid fuels flows and the fuel feed pipe, above-mentioned central angle scope can both make gas stream be evenly distributed in the viscous liquid fuels stream.
Central angle is during less than 90 °, and the fluid resistance of gas supply assembly will sharply increase, and the distribution of gas in the viscous liquid fuels is just inhomogeneous, and promptly the mixing and burning of fuel and gas all will worsen.
Central angle is greater than 120 °, and fuel is when sending into fuel feed pipe unevenly, can be near fuel feed pipe outer surface viscous liquid fuels flow liquid face edge to last several rounds that viscous liquid fuels stream is supplied gas.At this moment partly gas can not enter in the viscous liquid fuels, has reduced the generation intensity of bubble and the uniformity coefficient that bubble distributes in viscous liquid fuels stream, causes fuel combustion to worsen.
The radial height of gas supply assembly sector drum is preferably 0.3～0.5 times fuel feed pipe channel diameter.
Test shows, gas stream is evenly distributed in viscous liquid fuels stream, strengthens the formation of bubble and it is evenly distributed in the viscous liquid fuels, thereby improve the burning of fuel.
When aforementioned proportion less than 0.3 the time, the fluid resistance of gas supply assembly sharply increases, the degree that is evenly distributed of gas reduces, burn deterioration.
When aforementioned proportion greater than 0.5 the time, the fluid resistance in hole can make the uniformity coefficient of distribution of gas in the viscous liquid fuels reduce burn deterioration less than the fluid resistance of gas supply assembly equally.
The diameter in each hole preferably also is the radial height of 0.2～0.3 times of gas supply assembly sector drum.
Like this, gas can enough be evenly distributed in the viscous liquid fuels stream, and the size of bubble is approaching consistent, thereby has improved igniting and burning condition.
If aforementioned proportion is less than 0.2,, can reduce to the uniformity coefficient of viscous liquid fuels air feed because the fluid resistance in hole is greater than the fluid resistance of gas supply assembly.
If aforementioned proportion is greater than 0.5, because the fluid resistance of hole and gas supply assembly is incompatible, the air feed uniformity coefficient also reduces.All above-mentioned situations all can make burning condition be damaged.
The combustion method of the viscous liquid fuels of recommending above and equipment thereof not only simply but also reliable, can also guarantee abundant meticulous mixing of high viscosity fuel liquid and oxidant, guaranteed that fuel is lighted a fire reliably and burning effectively.
The combustion method of the viscous liquid fuels of recommending above is used for viscous liquid fuels and solid-fuelled mixture is effective especially.Therefore, this method can be used for changing liquid fuel into this mixture.

The foam shape fuel mixture that contains bubble mixes with oxidant stream, until forming flammable mixture.Oxidant stream rotates in advance, sends into along the periphery of the fuel stream that contains bubble then.The centrifugal action of oxidant eddy flow is containing on the viscous liquid fuels stream of gas, makes the rotation of fuel stream, thereby oxidant stream and the viscous liquid fuels stream that contains bubble are scattered with the shape of divergent cone.
The weight flow of steam-air mixture is 0.9～5 times of viscous liquid fuels weight flow.The tar heavy oil defective material that generates of pyrolysis solid fuel for example, the weight flow of its steam-air mixture is 3 times.
