Description
Technical field
The invention belongs to combustion technology, and in particular to a kind of method of the cracking burning of methanol.
Background technology
Existing methanol combustion method is changed to methanol fuel from Light Oil Burning Machine and just directly used, and the theory of combustion is not
Change.But methanol burning and light oil burning are very different, one is that methanol gasifying latent heat is very big, and second is that methanol has in itself
Oxygen, existing combustion method by methanol after atomizer sprays by arc ignition, directly burnt by blower fan air feed, work as methanol
After atomizing particle is ignited, methanol particle first has to gasification, and methanol gasifying heat absorption causes combustion zone temperature to reduce so that methanol fire
Flame temperature is low, and flame is elongated, incomplete combustion.Other original bumer of light fuel wishes the fuel particle size after fuel atomization
As far as possible small, to obtain as far as possible big surface so as to the gasification fully burning rapidly of light oil particle, this situation is in bumer of light fuel
Effect is positive, but methanol atomizing particle tiny in methanol combustion process has bigger surface, these molecules
Gasification rate faster so that combustion zone temperature is lower, so fired state is bad.
It is to copy benzine blow lamp principle to have some solutions at present, and methanol is first passed through a coil pipe heated or one
Closed cavity gasification cracking sprays burning by nozzle again, and coil pipe or airtight cavity are jetted out flames heating by methanol burning,
Although the problem of solving ignition temperature and burn complete, the internal high temperature that this mode belongs to this kind of closed cavity of coil pipe lacks
Oxygen environment is cracked, because cracking temperature is not easily controlled, so must have carbon distribution generation, use time not length will coil pipe block up
Plug.Coil pipe is blocked and can also caused the accident, so the method for this closing space internal gasifier cracking can not solve burning at all and ask
Topic, this combustion system is using preceding also needing to preheat coil pipe, using very inconvenient.
The method that also having other at present improves methanol burning mainly adds various additives in methanol, and modifying agent increases
Cost can also increase while heat value, not solve problem from basic.
The content of the invention
The combustion system that the present invention is cracked after being atomized using a kind of methanol in unlimited environment in burning, is thoroughly solved
The problem of producing carbon distribution in cracking, the present invention can be burnt complete, flame temperature is high, using being not required to pre- with long-term stable operation
Heat, the combustion heat value of fuel is also add by cracking, and the invention cost is very low, is that one kind can be promoted the use of using reliable
Effective ways.
The principle of thermal cracking is produced when methanol atomizing particle burns in ceramic heat storage body in this unlimited environment：
Methanol passes through the particle that methanol atomizer sprays, due to methanol surface tension.So it is ball in the air to suspend
Shape particle, when atomization methanol particle first passes through the electric arc of ignition electrode generation, some methanol atomizing particles are ignited first, after lighting
Methanol flame begin to warm up heat storage inwall and conduit wall into ceramic heat storage body, heat storage passage is rapidly heated to methanol
Cracking temperature.Substantial amounts of methanol atomizing particle is continuously entered in ceramic heat storage body passage simultaneously, in high temperature environments, these methanol
Particle surface gasifies first, forms a gasification concentric sphere volume, liquid fuel combustion process is stratified combustion, so aerobic
Particle gasification top layer is first burnt under hot environment, and surface combustion can seize the oxygen around surface, though such situation is caused
Right integrated air amount is superfluous, but is anaerobic condition inside particle, therefore the heat radiation heat under the hot environment of heat storage passage
Conduction penetrates particle top layer so that inside reaches cracking temperature, and inside produces thermal cracking, and hydrogen and carbon monoxide are generated after cracking
Etc. other components.Heat required for the latent heat of methanol particle gasification and cracking is then provided by ceramic heat storage body.Due to atomization
Grain size and the temperature difference that position is caused in ceramic heat storage body passage can generate different cracking components.After cracking
Product and air are blended in ceramic heat storage body passage because the effect of blower fan blows to exit, the change gas set in exit
Flow in the presence of the passage of direction, produce eddy airstream.This changes the flow velocity that airflow direction passage slow down gaseous mixture so that store
The flow velocity of hot each passage of body is consistent, and the change airflow direction passage generates strong disturbance so that component and sky after various cracking
Gas is sufficiently mixed burning, forms extremely short swirl flame, and produce the high temperature more than 1300 degree.
The feature of the present invention is as follows：Primary particle size is distributed（100-800 microns）Methanol atomizing particle and certain pressure
（100-2000pa）Air mixing after light and blow over a profile to have the ceramic heat-storing of vertical passage inside tubular structure
Body.
Described ceramic heat storage body, the temperature of heat storage inwall and vertical passage will be maintained at methanol thermal cracking temperature when using
It is more than degree.
Described ceramic heat storage body heating, can be produced after being lighted by the methanol atomizing particle of ceramic heat storage body passage
Heat ceramic heat storage body is maintained more than methanol decomposition temperature, or as external heat source provide ceramic heat storage body needed for temperature
Degree.
Described ceramic heat storage body, exit or internal settable one or more snippets change airflow direction passage.
The methanol atomizing particle of described certain particle diameter, is realized after being pressurizeed by methanol by atomizer, its
Grain size can be obtained by changing methanol pressure or selection atomizer jet size.
Described methanol combustion method also includes：The blower fan of ceramic heat storage body longitudinal size and adjustable air volume is selected to coordinate,
To obtain the residence time that methanol atomizing particle is required in ceramic heat-storing body.
The ignition location of described methanol atomizing particle is at the import of ceramic heat storage body vertical passage.
Described ceramic heat storage body can be assembling structure, and material may be selected IR Radiation Ceramic Materials and be made.
